Settings on the computer:
There are two options for the development of events:
The first is SIMply to connect the TV via LAN to a computer without Internet access. In this case, you need to register a static IP address on the network computer. let it be 192.168.1.2 with a mask 255.255.255.0:
On the TV, you will also need to register IP from the same subnet. for example, 192.168.1.3.
The second is to connect the TV to the Internet via a computer. To do this, your computer or laptop must be connected to the Internet via Wi-Fi or USB modem. Then we will SIMply use the ICS mechanism built into Windows. Internet Connection Sharing. It allows you to allow access to the global network for local clients. To do this, in the network connection, select the one through which you are connected to the Internet and right-click on it. The connection properties window will open in which we are interested in the “Access” tab:
On it you need to check the box “Allow other network users to use the Internet connection of this computer.” Below you need to select “Local Area Connection” or “Ethernet” and click OK. In this case, you do not need to register IP addresses. neither on the network card, nor on the TV. everything will be assigned automatically.
How to connect a TV via LAN to a computer using LG as an example
Most modern Smart-TV TVs are equipped with at least a LAN port for connecting it to the Internet via a router. At the same time, on TV you can not only surf the Internet, but also watch movies from computers connected to the same network. But not every apartment still has a router, but I want to watch movies and get out on the Internet from a TV set. What to do? You can connect the TV to a computer via the LAN connector directly. For this we need a network cable.
Note: A slight complication may arise here. a regular “straight” ethernet cable may not work, although modern network cards are able to “flip” the cable logically. Then you will need to try a reverse LAN cable (the so-called “Cross-over”).
We turn on one end of the network patch cord to the computer’s network card:
The second is to the LAN port of the TV:
We check whether the devices are linked by indicators. After that, we proceed to connect the TV to the local network. Let’s start with the computer’s network card.
Settings on the TV:
Everything is very SIMple on the TV. I’ll take an LG TV as an example. On other brands, despite the external difference in the menu, the meaning of the actions is the same. just proceed in the same way.
Go to Settings and go to the Network section:
We select the item Network settings. A special configuration wizard will open:
Then it all depends on which of the options you have chosen and configured on your computer. If we just connect the computer to the TV via the LAN port, then click on the “Configure connection” button and register the IP address 192.168.1.3 with the mask 255.255.255.0.
If you followed the second path using the ICS mechanism, then SIMply click on “Next”. The automatic configuration of the network connection will start:
Click on “Close”. That’s all. you have successfully connected the TV to the computer via the LAN connector.
Connecting and setting up a computer with a TV in Windows
To connect, just choose the interface that is best for you and connect the computer to the TV through it, after turning off both devices. Do not forget to indicate in the TV menu the selected interface as the main one. After switching on, the connection with optimal settings should occur automatically. If this does not happen, you need to go to manual configuration of the connection in the Windows environment.
Setting up a connected TV and computer via a digital interface is very SIMple. For the best image quality, you just need to adjust the maximum possible screen resolution (usually Full HD. 1980x1080px) and specify the maximum horizontal screen frequency (Hz). Each version of the Windows operating system will have a slightly different step-by-step setup, but very SIMilar.
In Windows Vista 7 or 8, you need to right-click on the desktop and select the screen resolution. Then in the window adjust the screen. on the right, click the find button and the connected TV should be found. After that, you need to set the maximum resolution. And in the item additional parameters, you need to select the maximum scan rate by selecting the monitor and the screen refresh rate in the tab (see photo).
In Windows XP, you need to right-click on the desktop and select display properties. Then select options. click on the image of the second monitor and tick the box to expand the desktop. In the tab additionally select monitors and select the maximum resolution and scan rate.
Interfaces for connecting a TV to a computer
Analog technologies have imperceptibly gone down in history, giving way to digital technologies. Of course, digital has successfully mastered in modern LCD TVs, which made it possible to connect, using digital interfaces, the source and the TV more flexibly, and with better image quality in contrast to analog signals.
Therefore, to display the image on the TV screen from a computer or laptop, it is better to use digital connection interfaces, such as: hdmi, dvi, displayport or wireless hdmi via Bluetooth.
These interfaces not only allow you to transmit a signal but also audio, which SIMplifies audio switching and allows you to use the built-in acoustics of the TV without additional wires. And the latest version of hdmi 1.4b or displayport 2.1, allows you to transmit 3D signal with a screen refresh rate of 120Hz.
dvi and displayport interfaces are rarely found in TVs, but very often they are found in computer cards and sometimes they are even the only ones, or hdmi and displayport can be in option. mini. Therefore, in cases of incompatibility of interfaces, an adapter or an adapter cable from one interface to another may be required for connection (see photo).
But when using adapters, there may be problems with the transmission of high-resolution images (for example, 1920x1080px or more), sound or full-fledged 3D images. Or, poor quality adapters can degrade the image, like wireless signal transmission via Bluetooth. Note that you can face SIMilar problems when using low-quality cables.
For the rest, it does not matter whether a stationary computer or laptop, nvidia or ati card, or which TV company is used: Sony, Philips, Samsung, Panasonic, etc. since all these devices are very SIMilar.
How to connect a computer to a TV via Wi-Fi
In this article we will tell you how to properly connect a computer via Wi-Fi to a TV, consider several of the most popular options today. The meaning of such a connection is the ability to conveniently watch files and photos stored in a computer or broadcast over the Internet on a large screen.
What you need to establish a wireless connection?
Since Wi-Fi involves the exchange of data via a radio channel, first of all, you need to make sure that your Smart TV, like your computer, is equipped with a built-in Wi-Fi module or optionally supports this technology.
As for laptops, almost all of their modern models have a hardware built-in Wi-Fi module. If you want to connect a stationary desktop to the TV, then you will have to additionally purchase a special Wi-Fi adapter for it.
The adapter can be made in the form of a PCI-card built into the system unit with an antenna or an external USB-module that looks like a regular USB flash drive. The same external Wi-Fi adapter may need to be connected to the USB connector of the TV, if it is not initially equipped with a built-in module. To avoid connection and setup problems, it is best to purchase adapters from the same brand as your TV.
It will not be superfluous to pay attention to the version of the Wi-Fi standard that the modules support. Better to dwell on the most current and fastest version of IEEE 802.11n. It has a wide bandwidth and will not cause delays and freezes on the TV screen. Also, don’t forget to update the driver versions for all network devices.
The easiest way to organize the wireless transfer of images or music from a computer (laptop, tablet) to a TV is as follows:
- On a local area network LAN via Wi-Fi router (computer. router. TV).
- Intel Wireless Display (WiDi) or Wi-Fi Miracast (wireless monitor).
Connecting the TV to a Computer Using a Wi-Fi Router (DLNA Technology)
To organize wireless data transfer between several devices, it is required that they have built-in or external Wi-Fi modules and be combined into a single local network via a Wi-Fi router. At the same time, the TV must support DLNA technology. a set of universal standards for multimedia exchange. This feature can be checked in the accompanying technical documentation, although today all Smart TVs support DLNA.
We turn on the Wi-Fi router, configure it to work in DHCP mode (automatic distribution of network settings) and assign a password to enter the local network.
We connect the TV to the local network
From the remote control we enter the TV menu, go to the “Network” item and open the “Network Settings” tab. In the opened wizard for configuring network connections, activate the item “Wireless connection”. From the list that opens, select your Wi-Fi network, wait for the connection check to pass, and enter the access password.
If the router supports WPS technology, then connecting the TV to a Wi-Fi network can be even easier. It is necessary to select the appropriate item (WPS / PBC) in the TV setup wizard and hold down the WPS button on the router for a while until the connection is established.
Installing a media server on your computer
SIMply put, in order to transfer files to a TV over a local network, you will need to create several folders on your computer for storing various types of multimedia files (, music, photos). After that, these folders should be opened with extended access from all devices connected to a common network, including from the TV.
The easiest way to do this is using any media server program that is convenient for you, which is designed to organize access to network resources from various connected devices. There are a lot of programs that solve this problem: AllShare (Samsung Link), Samsung PC ShareManager, SmartShare, Serviio media server, Plex Media Server, Home media server and others.
The program should be downloaded to a computer, installed, conveniently configured and launched. After starting the media server, you need to go to the TV settings, where you will see the folders you have assigned with the multimedia content available for demonstration. Now you can view computer files by launching them directly from the TV screen.
Connecting the TV to a Computer Using WiDi / Miracast Technology
Unlike DLNA technology, this option for wirelessly displaying multimedia information from a computer to a TV allows you to view not only files recorded and stored on the computer’s hard drive, but also those that are played online on its built-in web browser.
True, the WiDi / Miracast technology (screen mirroring) is very demanding on computer resources, therefore it is supported only by individual computers (laptops, tablets) with powerful hardware filling. And, of course, these advanced technologies must be implemented in the TVs themselves. If the TV only optionally supports WiDi / Miracast, then you will have to additionally purchase a special adapter, which can then be connected to one of its HDMI ports.
The principle of wireless monitor technology is that the picture that is currently displayed on the screen of your computer is compressed according to a special aLGorithm, after which it is mirrored over the Wi-Fi radio channel to the large TV screen. At the same time, it is not at all required to connect the TV to a local wi fi network together with a computer using a router: the TV receiver organizes a separate mini-network for communication only with a PC.
To start transferring an image, you need to install a special Intel Wireless Display application on your computer (if it was not preinstalled) and start broadcasting in it. In the TV Menu, the WiDi / Miracast function must be activated. This can be done in its settings by going to the “Network” tab, and then go to the item “Miracast / Intel WiDi”.
The shape of the remote control body is ergonomic, and the batteries located along the body improve the balance. The numeric buttons and the two most important rocker buttons are large, there is a convenient four-way navigation button with an OK button in the center, the button labels are contrasting and large enough. It is somewhat inconvenient that the menu button is lost among the small buttons in the front of the remote control.
The slide switch determines the mode of operation of the group of buttons designed to control the equipment connected to the TV. In the TV position, signals from the remote control are transmitted to the TV and from it via SCART or HDMI (Q-Link and Viera Link functions) to the connected equipment, and in this mode the TV’s own multimedia player is also controlled by these buttons. By switching the slider to DVD / VCR. This remote control can directly control Panasonic equipment (tape recorder, DVD player, etc.). The remote is equipped with two IR emitters: one is directed forward, the other is forward and downward, which allows you to keep the remote pointing slightly upward. this is more convenient and the button labels are better visible.
How to connect a TV to a computer or laptop
In the modern world, TV and computer are increasingly becoming a single whole. It is no longer uncommon for a computer in the house to be connected to the TV as the main multimedisource or just for entertainment on the big screen. A large screen diagonal may also be needed for laptop owners or for professional work.
To change the computer monitor to a large diagonal screen, manufacturers are also pushing the constant price reductions for TVs with improved image quality, and filling among their predecessors. over, today are significantly reduced not only for TVs on TN matrices, but also on IPS matrices, and plasma panels. What further encourages the purchase of lovers of computer entertainment on a large screen with the highest quality image.
Testing in stereoscopic mode
To create a stereoscopic image, Panasonic plasma TVs use a full-frame interleaving method. Frames for the right and left eyes are sequentially displayed on the TV, and active glasses synchronously with the frames overlap the eyes, leaving open the one for which the currently displayed frame is intended. See here.
There are no glasses in the delivery set of this TV, they will have to be purchased separately. At the time of this writing, Panasonic was offering 4 glasses models in the Russian market: the universal TY-EW3D10E, which we reviewed in the article about the Panasonic Viera TX-PR50VT20. and three new models TY-EW3D2LE, TY-EW3D2ME and TY-EW3D2SE, differing in body sizes and colors. The model with the index L is intended for large heads (if averaged over sizes, it is more likely for men), M. for medium (relatively speaking, women) and S. for small ones, i.e., thinsp is more likely for children. For testing we got glasses TY-EW3D2LE. as you can see in the photos, with a brown panel.
These glasses differ for the better from the first universal model in a number of characteristics. First, the design: now the person wearing Panasonic 3D glasses does not resemble a fly person. Secondly, the new glasses are much lighter. 39-40 g against the pressure on the bridge of the nose 63 g. Thirdly, the glasses of the TY-EW3D2 series are equipped with a built-in battery, rechargeable via a standard mini-USB connector.
Fourth, the new glasses are more comfortable to wear, since they cover the head with flexible arms (there is no need to use a fixing cord), and the soft non-replaceable nose pad (two removable nose pads are attached to the old glasses, which are not very securely fixed and therefore easily lost) sits comfortably on the bridge of the nose and, as it were, sticks to it.
Fifth, the glasses of the new glasses are located closer to the eyes, which greatly reduces the likelihood of glare from extraneous light sources. Only one new glasses lose to the old ones. the size of the glasses. As a result, the viewing angle decreases slightly, but this is noticeable only when new glasses are used in conjunction with corrective glasses, when the glasses of stereo glasses are located at a greater than usual distance from the eyes. By the way, the included cable for recharging glasses is relatively short and tough, so it will not work at the same time to watch stereo and recharge glasses.
Glasses are synchronized by IR signal from the TV. The receiver is located centrally between the glasses. The glasses are switched on and off with a slide switch, which is more convenient than the button on the old model. In this case, a red mark is visible in the on position. In addition, in the active state, the red indicator blinks dimly with a period of several seconds. The glasses are turned off either by the same switch, or after about a few minutes of lack of sync signal reception. The range of operation is large. in fact, glasses receive a signal if they are in front of the plane of the TV at a distance of up to several meters and are directed towards the screen. During temporary interruptions in receiving the sync signal, the glasses retain synchronization for several seconds, and when the interference is removed, they restore synchronization almost instantly.
The photographs show that the lenses of the glasses have a slightly greenish tint, but when working in 3D mode, they become closer to a neutral gray tint. Also, in 3D mode, additional color correction is introduced so that the tint of the glasses and partial cutoff of the glow of the phosphor does not lead to a significant change in the color balance. So, without glasses when choosing a Cinema profile in 3D mode, the white point has a color temperature of 5920 K and Delta E 15.1, while through glasses. 5440 K, and Delta E decreases to an acceptable value of 1.71 (for glasses of the TY-EW3D10E model we got 6140 K and 0.9, respectively). In terms of spectral characteristics, the old and new glasses practically do not differ, which is shown by the spectra obtained through these glasses when the white field is displayed:
Glasses transmit light about the same. the brightness in stereoscopic mode decreases by about 6 times (due to overlapping eyes and absorption on the glasses). To be precise, the new glasses are about 5% lighter, but this difference is not significant.
The graphs below were obtained with synchronous recording of transmission through the right and left glasses of glasses:
It can be seen that the opening of the LCD gates is relatively slow, while the closing is almost instantaneous. The time interval when both the right and left glass are closed is very short. Note that in this test, an incandescent lamp powered from an alternating current 50 Hz was used as a light source, i.e., the brightness changed slightly with this frequency, so the shape of the peaks has characteristic distortion.
The TV supports three methods of receiving a stereo pair via HDMI-interface. packed frames (Frame Packing), when two full frames (up to 1920 x 1080 pixels each) are transmitted for both eyes, and two combined formats: horizontal (Side by Side, on the right half of the frame is halved horizontally for one eye, in the left half for the other), and vertically (Top and Bottom, SIMilar to the previous one, only frames for the eyes are placed in the lower and upper half of the frame). Of course, regardless of how the TV receives a stereo pair, the image in 3D mode is always displayed in sequential mode. a frame for one eye, then a frame for the other eye. The combined versions have the disadvantage that the frames for the eyes have a halved horizontal or vertical resolution relative to the transmitted frame. There is a 3D Picture Format option in the TV menu. which defines the frame extraction mode for the eyes.
If it is equal to Auto. then the transmission method is determined automatically (apparently, according to the signs in the signal transmitted via HDMI. accordingly, the source must support 3D Over HDMI mode), and only in this case the Frame Packing mode is supported. If the 3D Image Format is Horizontal Composite or Vertical Composite. then the TV extracts the frames for the eyes in an appropriate way. In these two modes, the picture for the eyes can be swapped. If you set 3D Signal Format to Normal. then the original frame will be displayed on the screen to help determine the transmission method. Compared to Panasonic Viera TX-PR50VT20 TV. in this, one more mode of outputting a stereoscopic image appeared. the mode of automatic conversion of a regular flat image into a stereoscopic one. This mode is enabled when you switch 3D Image Format to 2D 3D. In this mode, both the displayed image and the graphic menu of the TV are displayed in stereoscopic form, while the 2D 3D Depth parameter affects the magnitude of the stereo effect. You can quickly get to the stereoscopic mode settings from the VIERA TOOLS menu. called by the button of the same name. It is noteworthy that the combined modes and 2D 3D conversion mode are available when receiving television programs, with any method of connecting to an external signal source, as well as when playing multimedia files using a TV player from an SD card or from a USB drive, and even when working with a server UPnP over the network. For example, from an SD card, the TV reproduced in stereoscopic form a test recorded by a Panasonic HDC-SDT750 camera (thanks to Sergey Merkov). The TV determined that the is stereoscopic without assistance. Likewise, MPO (Multi-Picture Object) stereo photographs are rendered in stereoscopic mode by default. In the case of ordinary files with a composite image, the type of registration must be specified manually.
We tested the stereoscopic Frame Packing mode using a Panasonic DMP-BDT100 Blu-ray player and a demo Blu-ray disc with 1080p and 720p stereoscopic clips. The demos looked great: the stereoscopic effect was present, there was no flicker on stationary parts, there was no strobe on slow-moving objects (but of course it appeared on fast-moving objects), separation for the eyes was effective, brightness was sufficient, contrast was high, and the picture 1080ps. very clear.
Also, Frame Packing mode can be used when connected to a card with HDMI or DVI interfaces capable of operating in HDMI 1.4 mode. At the same time, in Full HD resolution (1080p, 1920 by 1080 pixels), you can get 24 fps for each eye, which is enough for watching movies, and in a resolution of 1280 by 720 pixels. up to 60 fps for each eye, which is acceptable frame rate for dynamic games. One of the advantages of this way of connecting to a card is the ability to play Blu-ray 3D discs from a computer on a TV (or projector) in stereoscopic mode.
Shortly before these tests, NVIDIA announced support for 3DTV Play in NVIDIA Release 260 Beta drivers. and in fact, at the time of the tests, AMD announced support for AMD HD3D technology. Both of these technologies are directly related to stereoscopic image output when connected to a display device with HDMI 1.4 (along with output to devices that support 120 fps output). According to manufacturers’ data at the time of our tests, 3D output over HDMI 1.4 was supported by cards based on NVIDIA GeForce 400, 300 and 200 series processors (see the list in the Blu-ray 3D playback section) and AMD Radeon HD 6870 and HD 6850 (see the list. in the Blu-ray 3D column).
We tested the AMD variant first. Testbed configuration: Microsoft Windows Vista Business 32 bit, AMD Radeon HD 6850 engineering sample, Catalyst driver v10.10. Catalyst drivers alone are not enough for stereo output, they need support: for 120Hz output, this is the iZ3D software. and for stereo output over HDMI 1.4 you need to install TriDef software. We used the 14 day trial version of TriDef. This software allows you to run games in stereoscopic mode, and also allows you to view stereophiles and images that are launched for playback using a special player. The results are mixed. On the one hand, the interface of the program itself was demonstrated in stereo mode, it was also possible to watch photos and films in stereo (though, for some reason, for some reason, two movie frames were displayed on the screen, but both in stereo), but none of the tested games in stereo mode was launched. For example, when launching the demo version of the game Dirt 2, TriDef received a message to use DirectX version 9, although the system was using version 11, which is in the list of compatible ones on the TriDef page. It is not necessary to use TriDef middleware to watch movies in stereo and Blu-ray 3D discs, in theory a software player like CyberLink PowerDVD 10 Ultra 3D (which we used) should be sufficient. However, it was not possible to watch Blu-ray 3D on the TV from the computer, since the corresponding output mode could not be selected on the settings page of this player. As a result, the ability to output stereoscopic images when connected via HDMI 1.4 using an AMD Radeon HD 6850 card has been proven, but the corresponding software still needs to be improved.
In the same computer, after removing the AMD Radeon HD 6850 card and removing the Catalyst drivers, we installed the card on an NVIDIA GeForce GTX 275 processor. This card did not have an HDMI output, therefore, to connect to the TV, we used an appropriate adapter cable from DVI to HDMI. For stereo output, you need to install the card drivers and the 3D Vision software kit (we used version 260.89 and build version 1.36, respectively). In addition, to activate the stereoscopic mode, it is necessary to connect the 3D Vision IR emitter, which is not used for its intended purpose, but works as a key confirming the presence of the 3D Vision kit. The fact is that 3DTV Play technology is available for free to owners of the 3D Vision kit, and those who do not have it will need to pay a certain amount.
Unlike AMD’s solution, the NVIDIA software suite is self-sufficient, since it allows you to launch games in stereoscopic mode without any intermediaries and additional programs, as well as view movies and photos in stereo (the players required for this are included in the kit), except for Blu-ray 3D playback on a computer requires a software player such as CyberLink PowerDVD. Unfortunately, the situation repeated itself: in CyberLink PowerDVD options, stereo output over HDMI 1.4 was not available. However, in stereo, I managed to watch photos, films and run at least one game (H.A.W.X.) from the available ones.
After the article was published, we received an invitation from the Russian office of NVIDIA to come to them and make sure that Blu-ray 3D playback using 3DTV Play is still possible. We did not refuse such an offer. Indeed, we were shown playback in stereoscopic mode of a test Blu-ray 3D disc (or rather, its image) on a second-generation ION-based minicomputer,
at the same time, a Panasonic VIERA TX-PR50VT20 TV was connected to the computer via HDMI.
Our failure described above should probably be attributed to the fact that we did not install an up-to-date CyberLink PowerDVD update. By the way, along the way, one more pleasant point was revealed. in fact, when outputting via HDMI 1.4 for Blu-ray 3D playback, there is no need to purchase 3DTV Play software or connect a 3D Vision emitter.
We express our gratitude to NVIDIA Russia and personally Irina Shekhovtsova for organizing this mini-test.
We also tested the function of automatic conversion of a normal image to a stereoscopic one. This function works both in the case of a still image (for example, when viewing photographs) and in the case of a dynamic picture. For the separation of objects in depth, apparently, the boundaries of objects are determined, the brightness of the objects and, possibly, the speed of their movement are analyzed. The overall result was not very impressive. Yes, there is some effect, but real stereo looks much better than one generated from a flat image.
In general, this model is SIMilar to the previously tested Panasonic Viera TX-PR50VT20 TV in terms of stereoscopic image output quality. In particular, there is no crosstalk for dark objects against a light background, but for light objects against a dark background, parasitic outlines can be seen. The brightness of the image is sufficient even in stereoscopic mode, but it is still better to look in a darkened room, and it is advisable to prevent the appearance of glare on the screen from external light sources, since glare badly affects the perception of a stereoscopic image. However, there is still one difference. In the TV Panasonic Viera TX-PR42GT20 in stereoscopic mode, the image output is interlaced. This can be noticed, for example, when connected to a computer (especially in a resolution of 1920 x 1080 pixels), when graphic elements with contrasting horizontal lines with a thickness of one pixel are displayed on the screen in stereoscopic mode. Real images are always sufficiently smoothed so that interlaced output has little to no impact on image quality when watching movies (even in Full HD resolution) and photos.
Problems connecting the computer to the router via a network cable
After connecting, the status on the notification panel may not change, you will see the computer crossed out with a red cross.
In this case, first of all, you need to check the cable with which you connected the computer to the router. How to do it? You can, for example, take another cable, or the cable that runs the Internet directly to the computer. If this connection status changes (even if a yellow triangle appears). then the problem is in the cable. Perhaps there is something gone. Just change it.
It is possible that the network card is SIMply disabled. Let’s check. Go to Control Panel \ Network and Internet \ Network Connections and find Local Area Connection there. If the status is Disabled next to it, then right-click on this connection and select Enable.
If there is no such connection as Local Area Connection at all, then most likely the driver is SIMply not installed on your network card. Download and install the driver. If there was a disc included with the computer (laptop), then most likely it contains this driver.
How to connect a computer to a router via a network cable (LAN)?
As a rule, most of the problems arise when connecting to a router over a wireless network. And connecting via a network cable should not cause any difficulties. But, I have already met SIMilar questions several times, and decided to write a small instruction with a photo, in which I will tell you about how to connect a computer (or laptop) to the router using a LAN cable.
And what to write about here, they took a cable, connected it to a router, then to a computer, and everything is ready. But still, it may come in handy for someone. As a rule, modern routers have 4 LAN connectors. This means that you can connect 4 devices via a network cable. And they will all receive Internet from a router, or work in a local network. By the way, read this article on setting up a local network.
We will need:
We take our network cable, it looks like this (you may have a slightly different one, I have a different length):
We connect one end of the cable to the yellow connector (LAN) of our router.
It doesn’t matter which of the four connectors you plug the cable into.
Now we connect the other end of the cable to our computer, or laptop.
This is what the network connector looks like on a computer:
After connecting the network cable, one of the four indicators on the router should light up, which indicate the connection to the LAN connector.
Now we look at the computer screen. If on the notification panel (bottom, right) you see this connection status (as in the screenshot below). then all is well. Internet is already working.
But, in such a seemingly SIMple way, problems can also arise. Now some of the most popular, we will consider.
Plugged in the cable but the connection without internet access
And this can be. This problem looks like this:
First, you need to determine what the problem is. This could be due to a problem on the router side. For more on this, see this article.
But I’ll tell you in a SIMple way. If other devices work normally from this router, and the Internet is on them, then most likely the problem is on the computer itself. This is clear :).
And as a rule, this problem is one.
Go to Control Panel \ Network and Internet \ Network Connections again and right-click on Local Area Connection. Select properties. Then select “Internet Protocol Version 4 (TCP / IPv4)” and click the Properties button again.
Set to get IP and DNS automatically and click OK.
This should help.
But, do not forget that, for example, there may be technical problems with the network card (perhaps it just burned out) and other very different reasons why a variety of problems may arise.
Here is such an instruction, everything seems to be SIMple, but it turned out not very small. Hope it is useful to someone.
TV Ethernet connection
We take the router in hand and look at the back panel.
Find LAN ports. They are usually signed.
It may happen that there is only one LAN port, and it is already occupied. In this case, we use a hub and a switch to “propagate” the port.
Next, we take the patch cord, connect one end to a free LAN port of the router, the other end to the Ethernet port of the TV.
We turn on both devices. On the TV remote control, press the “Setup” button. We select the menu item “Network”, then the submenu “Network settings: wired”.
On the remote we press “Ok”, and go to the second step. setting the network address of the TV.
The IP address can also be configured manually, but this is only necessary in rare cases when the computer network requires it (static address, non-standard subnet mask, etc.). If such requirements are not put forward, then we can safely set the “IP Autoconfiguration” mode, and the TV itself will coordinate its address with the router without your participation.
The same applies to the DNS server. we leave it on auto-tuning. Click “OK”.
Everything, a wired connection is established, you can access the Internet directly from the TV by launching the built-in web browser.
Connecting Smart TVs to a computer network
For a long time there have been so-called SMART TVs on the market. smart TVs. Their feature is that in addition to broadcasting the usual television, they have Internet access. By connecting to special network resources, such a TV is enriched with additional functionality. weather forecast, you tube, fitness, zoomby, skype, and a huge number of additional programs. And, of course, a SIMple Internet browser for regular Internet surfing. But after purchase, the TV must be configured to access the network, and since in most cases the home computer is also connected to the Internet, this article will teach you how to connect a TV through a router.
Depending on the manufacturer, smart TVs have different connection interfaces, which can be divided into the following categories:
Of course, you can’t do without the usual RF in antenna input for cable TV. Recently, they began to abandon outdated SCART ports, CI slots and composite connectors (bells).
Connecting to a router
So, we have the following scheme. an ADLS channel enters the apartment, the connector of which is connected to some multi-port router to which a computer is connected to access the Internet. The router is equipped with a Wi-Fi adapter. Our goal is to connect the TV to this router so that both the TV and the computer (or several computers, it does not matter) have access to the network.
There are at least two connection options. via the Ethernet port (wired), or via Wi-Fi (wireless). Let’s look at the wired connection first.
Wi-Fi TV connection
But it is much more convenient to install a Wi-Fi wireless network. It is more convenient in many respects. there are no wires spoiling the interior, setting is done without getting up from the couch, in some cases the transmission speed is higher (standard “n”). Let’s consider how to connect a TV to a router via Wi-Fi.
First of all, read the instructions for the TV, whether it is equipped with a wireless Wi-Fi module. If yes. lucky, if not. you need to purchase a separate Wi-Fi adapter.
We connect it to any USB smart TV adapter.
Next, go to the TV menu. In the “Network” menu item “Network settings: wireless” will appear. We choose it.
The TV will offer several options for further customization.
There are three options:
When you select the second item, a list of available networks will appear, select the required.
If the wireless network is protected by a password, a window will appear asking you to enter it.
Click “OK”. Everything, wireless connection established.
In this section, we will consider the possible difficulties of connecting via Wi-Fi.
The first possible nuisance is that you can’t set up Wi-Fi. For troubleshooting, we take any wireless device (laptop, smartphone, tablet), and install software on it to directly connect a TV to it. This software is on the installation disc of the TV, or can be downloaded from the manufacturer’s website. For example, for a Samsung TV, this program is called AllShare. After installing the software, we try to connect to the TV directly (the third item in the menu). If it works. Wi-Fi is fine, if not. the conclusion suggests itself.
The second reason is that the automatic network search function is disabled on some TV models. Read the instructions carefully and check this parameter.
The third reason is that the network is installed but there is no Internet access. Check the DHCP server on the router, try to disable it and configure the TV to a manual IP address. IP address 192.168.1.2, subnet mask 255.255.255.0, gateway # router address #.
Reason three. make sure that the purchased Wi-Fi adapter is really compatible with your TV model.
And the last, universal, advice. try to turn off and on again both the TV and the router, at times it helps to adequately detect each other.
Connecting the TV to a Computer Using a LAN Cable
Sometimes you want to watch a movie or play games on a large TV screen, since the monitor is relatively small and your eyes get tired of it quickly. In addition, I don’t want to wait until the film of interest is shown on one of the leading channels. In this case, they resort to such a procedure as connecting the TV to a computer using a LAN cable. It even allows you to watch IPTV on your TV and not pay for cable or satellite TV. To do this, first of all, you need a TV that supports DLNA or Ethernet technologies. This material will discuss which cable to connect the router and the TV and how to connect the TV to the computer through the router via a LAN cable.
To work on the second screen, in some cases it is worth making settings on a computer or laptop. To do this, you should:
- Right-click on a free area of the desktop and select the item “Screen resolution”;
- Select the parameter “Multiple screens”. “Expand screens”;
- As a result, two independent screens will appear, on one of which you can start watching a movie.
The configurations described above are more suitable when connecting TV and PC using HDMI and VGA cables. With the advent of new ways to connect and Smart TV, more and more people are starting to use Ethernet slots and stream movies and other content to the TV screen using Wi-Fi routers.
With a LAN connection, the only setting can be the registration of a static IP address and subnet mask. This requires:
- Go to “Network and Sharing Center”. “Change adapter settings”;
- Select the current network and click on it with RMB, selecting “Properties”;
- In the components select the TCP / IPv4 protocol and set the address and mask. For example, 192.168.1.2 and 255.255.255.0;
- Save changes;
- Go to the “Access” tab in the same window;
- Check the box next to the inscription “Allow other network users to use the Internet connection.”;
- Save changes.
Choosing a router
After that, some people will have a question: how to connect a TV to a router via a LAN cable, and which router to choose for this. Fortunately, there are very few problems that can arise when choosing a router. All modern routers cope with this with a bang. Therefore, if there is already a router at home, then it will be fine for connection. The main rule: the router must contain more than one LAN port for connecting external consuming devices to connect a TV and a personal computer or laptop.
The scheme of connecting TV to a computer via a LAN cable through a router does not carry any complexity. Everything is standard here:
- Turn on the router by connecting it to the outlet using the power cable;
- Connect the provider’s WAN cable through which the Internet is supplied to the router through a special WAN socket;
- Take one LAN cable and connect it to the computer and the router through the RJ-45 connectors on the network card and on the back of the device, respectively;
- Take a second LAN cable and connect it to the TV and the router through the RJ-45 connectors on the back of the TV and a free port on the back of the router;
Important! If you need to connect the TV through a router and branch the network, remember that you will need another LAN cable of suitable length.
Watching IPTV on TV from a computer
Viewing IPTV is a little more difficult to implement, but it is also quite realistic even for a beginner. First you need to download and install the VLC Media Player program from the developer’s official website (taking into account that HMS is installed and configured previously).
It is worth noting that another player will do as well, but VLC will be the best solution and it is really necessary, since Server will take a stream from it. After installing the player, you need to link it to the Home Media Server. For this:
- HMS starts up;
- Go to Settings. Media resources. Internet resources;
- The path to the folder into which the player was previously installed is written in a special column;
- In the folder where the IPTV from the provider is installed there is a file with the.m3u extension;
- The file is transferred to the program window, namely to the “Internet TV” folder located to the left of the main interface;
- The transition is made along the path “Settings”. “Transcoder”. “Transcoding profile”;
- It selects the incoming stream “Internet TV”;
- HMS reboots, and a list of available channels appears in the “Internet TV” folder on the TV.
Important! If there was no.m3u file in the folder with the installed IPTV, then you can find and download it from the Internet on the website of your own or someone else’s Internet provider
Realizing a PC-TV connection via LAN
If all the parts are assembled, then you can proceed to the connection. To do this, plug one end of the cable into the RJ45 slot of the computer, and the other into the same LAN port of the TV. Most often, it is located on the back of the TV, where power, speakers and other paraphernalia are connected.
After connecting, it is configured. To do this, you can use specialized programs for broadcasting and audio from a computer to a TV. They are often specific and suitable for setting up TV from only one manufacturer. One piece of software that works well on many devices is Home Media Server. It contains many flexible settings, as well as a function that allows you to broadcast IPTV directly to your TV.
Working with the software is very easy: to load a movie into it, you just need to drag it from your desktop or any other folder into the program window. After that, everything is ready for broadcasting and it remains to press the “Start” button. A window with source selection will appear on the TV, in which you should select “AllShare HMS”. This completes the setup. An interface for selecting the desired clip appears on the TV.
Important! The software allows you not only to view the recordings and broadcast them to the TV screen. You can also view photos from a hard drive or flash drive, as well as listen to music.
What is needed to connect a TV to a computer
To make a TV connection to a router via a cable, you need the following things:
- TV set with a connector for inserting an RJ-54 (LAN) cable;
- A personal computer or laptop with a network card;
- LAN cable.
Important! Integrated network cards are not suitable for the second point, but if the Internet connection does not need to be maintained throughout the entire time, then they will do too. The computer cable must also be of sufficient length, as in the case of a short wire, one of the devices will have to be moved and carried.
Settings on the TV
There shouldn’t be any special problems on the TV side either. The only caveat is that DHCP (Dynamic Host Configuration Protocol) must be configured on the network device to which the TV is connected. If it is not configured, then you will have to independently register all the configurations on the TV.
For basic setup, follow:
- Go to the TV configuration and select “Network”. “Network settings”;
- Configure the connection by giving the TV an IP address from the same subnet. For example, 192.168.1.3 and subnet 255.255.255.0;
- View and configure additional parameters or just click “Next”;
- Save settings.
Thus, the questions were considered: how to branch the Internet cable to a computer and a TV and how to distribute a Wi-Fi network to TV via LAN. Connecting two devices together on a router to view content is easy and SIMple. over, it is also interesting, because watching movies on a big screen and not waiting for them to be shown on any television channel is very comfortable.
