A data transmission standard developed back in 1987. Fifteen pins have this connector and provide analog video signal transmission to a monitor or TV with a resolution of 1280×1024 pixels.
Only the image can be transmitted with the VGA cable. Separate wires must be used to transmit audio signals.
It’s easy to connect. It is not a problem to find a cable 10 meters long. You can also connect from a computer via an HDMI. VGA adapter with RCA “tulip”, then sound will be played through the TV speakers.
- Sufficiently high resolution of the video signal;
- It’s easy to connect;
- There is a nest even on laptops.
- Sound is transmitted over a separate wire;
- Not all TVs have a VGA jack.
WiDi / Miracast technology
Allows devices to communicate directly with each other via a Wi-Fi connection without involving a router.
By connecting the TV to a computer using WiDi / Miracast, you can not only view the contents of the desktop memory, but also everything that you see on the network. These are films, TV channels, photographs, videos, etc.
- Install on the computer, if it is not there yet, the Intel Wireless Display program.
- Start broadcast.
- Activate the WiDi / Miracast item in the menu.
- You can watch.
Benefits of connecting via a wireless network:
- High switching speed.
- Excellent picture and sound quality.
- Lack of wires.
DVI has been in use since 1999. With its appearance, analog signal transmission was replaced by digital. DVI cable replaced SVGA. A characteristic feature of the connectors is the presence of side screws for fixing.
DVI with mono channel signal transmission provides a resolution of 1600 × 1200 pixels. With two-channel, the resolution increases to 2560 x 1600. This requires a special connecting cable with a large number of pins. Therefore, when choosing a cable, you should pay attention to the correspondence of the cable contacts and jacks. Three-channel data transmission provides up to 3.4 Gbps throughput on each channel.
On TVs, the connector is usually referred to as DVI IN, i.e. the device is working on receiving a signal. Video cards of computers and beeches are labeled. DVI OUT.
If the PDA does not have an outlet for such a cable, then you can use an HDMI. DVI adapter.
REFERENCE. Only the image can be transmitted with DVI. Separate cables must be used for audio signals.
DVI cables can be found up to 5 meters long.
- Laptops rarely come with these connectors;
- Extra wire;
- Sound is transmitted over a separate wire.
Setting up TVs is the easiest thing to do. You must carefully read the instructions and act without deviating. Even if there is no description of the device, there is no need to despair. TV menus are easy to understand and designed to be intuitive. You just need to remember which input the cable is connected to. Select the desired connection in the menu and the TV is ready to watch.
Setting up your TV and laptop
Configuring most modern gadgets is easy, the interfaces are specially designed for easy perception.
IMPORTANT: Driver updates may be required for all connected devices.
The SCART standard was developed by the French in 1978. All CRT TVs are equipped with it since the 90s of the last century. Initially, the main purpose was to connect the VCR to the TV. Currently, the standard is outdated, and such a connector is unlikely to be found in a modern TV.
But computer technology is still equipped with VGA connectors and TVs with Scart connectors, there are also many more. By connecting it with the VGA. SCART adapter, you can connect the TV to the computer.
IMPORTANT. If the TV is too old, and the video card is of the latest generation, they may not work.
- Universal cable for old TVs;
- Includes audio cord.
How to Setup Ethernet Wired Internet Connection For TV (Easy)
- Laptops and modern computers require an adapter.
RCA and S-Video
Good old tulip or RCA connectors are found in almost all TVs and many computers. The video signal plugs are colored yellow, and the audio plugs are white and red.
The clarity of video transmission is not high, but if there is nothing else, then this method can be used.
The tulip is connected to the TV, and to the computer through the S-Video connector. The sound will have to be played on a laptop or output on a separate wire.
- Has only for obsolete devices.
- Poor quality of the transmitted signal;
- A separate wire is required for audio transmission;
- Laptops are not equipped with such slots.
RCA and Scart
Some cable options, in particular RCA and Scart, can only be used in conjunction with special converters. This is due to the fact that there are simply no such outputs on the PC.
Most older TVs are often only capable of receiving RCA signals. This cable consists of three colored wires: two for audio, one for video. People also call them “tulips”. But in order to make such a connection, you must additionally purchase a special adapter. It can be HDMI → RCA or VGA → RCA.
The relatively modern Scart connector allows high-definition image transmission. What’s more, it can play both video and audio format at the same time. Unfortunately, there is no such connector on a computer. Therefore, again, you will have to resort to buying adapters.
Connection setup proceeds according to the same principle as similar methods.
Working with multiple displays
You can use multiple monitors at the same time as follows:
- The duplication mode is a complete coincidence of the image on both the PC and the TV. your actions are visible on all monitors connected to the system unit.
- “Expansion”. a mode for combining two screens so that each of them is independent.
To change the resolution on an individual device, select it through the “Screen” item and make the necessary settings.
Using a network cable
In addition to the above methods, a computer and a TV can be connected to view videos or photos on a large screen using a Wi-Fi router. This requires a LAN port on the equipment and a network cable, after which a special media server is installed.
- Connect the TV to the router using a network cable to the LAN jack and install the media server on it using the following steps.
- Download a program to broadcast data from a computer. most users choose the Home Media Server utility.
- After installing the program, select your TV in the menu of its settings, then mark the sections on the PC that you would like to view on it.
- Run the program.
- Turn on the TV, select the Source section in the parameters, after which a program will appear in the list through which you can view files from your computer.
In a similar way, two devices are connected directly through the LAN ports. on one side, the cable is inserted into the TV jack, the other end is connected to the same port on the back of the system unit, creating a network connection.
To combine the technique when using the above two methods, you need to set the DHCP network settings on the TV. If they are not automatically enabled, you should manually register the following data:
- In the operating system: go to the Control Panel, open your network and view its properties. select Internet Protocol 4 and write the IP address 192.168.0.1, the subnet mask. 255.255.255.0. DNS server combination matches IP value.
- We enter this data in the network settings of the TV.
If you followed the instructions, but the picture did not begin to duplicate, we recommend that you check the Ethernet cable (patch cord), which can be either “direct” or “reverse” (so-called crossover). Modern network cards can often work without problems with each of them. However, for old samples, the “direct” option is not always suitable.
To avoid mistakes during the setup phase, we advise you to use the “Configuration Wizard”, which is present in most TV models, and just follow the step-by-step guide.
There is also an alternative way for those who failed to start the broadcast using the above steps. After connecting both devices to the local network, select any file (or folder with media files) on your computer and right-click on it. In the list that opens, click “Transfer to device” (there may be other similar variants of names) and click on the one you need. A prerequisite is that at this moment the TV is turned on and is on the network. So, without any settings and additional utilities, you can quickly establish a video stream.
Video signal input via DVI cable
This connection method will allow you to enjoy digital rather than analog images, but still without sound.
Please note that there are different types of cables of this format, do not make a mistake when choosing and subsequent purchase. In general, the connection between the PC and the TV is established in the same way as in the previous method, only select the DVI format in the video signal reception settings.
As you can see, not every cable, together with the image, transmits an audio signal. For this purpose, one more is needed. with a Minijack connector at one end and with two audio-tulips (RCA) at the other.
The Minijack plugs into the PC headphone jack (green). Usually there is a designation on the case. And “tulips” (red and white) are connected to the corresponding ports on the TV.
It is also necessary to make a small adjustment in the computer parameters. This is done very simply. Right-click on the sound icon located in the notification area and select “Playback Devices”. Next, in the list provided, find the name of your TV, right-click on it, and then click on “Set as default”. Save the changes with the “Ok” button.
This method of supplying video and audio signals to TV is the most relevant and profitable today, because you will receive a high quality digital signal with sound. provided that your computer has a built-in HDMI card. Modern video cards and laptops are usually equipped with such a connector.
Using this connection, you can display a picture on a screen with a large diagonal without loss of quality, which will especially appeal to fans of cinema, various games.
When buying an HDMI cable, take into account the location of the equipment in the room. if the screen is located on the wall, you will not be able to simply insert a straight plug, since the cable is quite thick and stiff. There are various types of cables where the plug is turned 90 degrees or made in the form of a corner. it fits well between the back of the TV and the wall.
- Turn off the equipment from the network, connect it with a cable via HDMI connectors.
- Turn on the TV, in the connection parameters (Source or Input) select the required connection type.
It happens that one HDMI port on the TV is not enough, and to solve the problem there are switches. “hubs” that allow you to connect several devices to it at the same time.
There are several connectors through which the PC and TV are connected. DVI and HDMI cables carry a high quality signal, while using VGA format only allows you to get an analog image.
The subsequent choice of the cable depends on what sockets are on the equipment. it is important that they coincide or you could put an adapter on one of its ends.
If your computer does not have a built-in HDMI card, or you are going to connect it to your TV using a different cable format, you need to purchase an audio cable, otherwise you will only get an image. It is connected via an audio jack. a green round hole with a diameter of 3.5 mm. and connects the input on the PC soundbar to the connector on the TV or external speakers. Without such a cable, you will have to listen to sound through computer speakers.
This connection format will allow you to see an analog image without sound, which will not be too high resolution, respectively, of imperfect quality. However, if there are no other types of connectors, use this method to connect the equipment.
To do this, follow these steps:
- Turn off the computer, connect the equipment with each other using audio and video cables.
- Turn on the TV and select the connection item in the settings (the section may have the name Source or Input), stop at the VGA item.
- Turn on the computer. the desktop image should appear on the TV screen. Another monitor should appear on the computer in the desktop settings.
