The Laptop Does Not Connect To The TV Via HDMI

Cable versions

The Laptop Does Not Connect To The TV Via HDMI

Unlike many devices, the HDMI interface has a reverse connection between any of its versions. For example, you can use a first generation cable and use the data transfer from a second generation connector. However, in this case, the baud rate and picture / sound quality will be consistent with the cable standard, not the connector.

Also, many experts recommend paying attention to the cable length / thickness ratio. The fact is that the market is full of fakes, and if there is no way to learn more about the characteristics of the cable, then you should pay attention to its appearance.

First, if the cord is long, then as it grows, the thickness should also grow. That is, a cable with a length of one and a half meters will be much thinner than a cable with a length of ten meters.

Second, safety comes first. Cable manufacturers, in order to protect their products, put special filters that prevent electromagnetic interference. Outwardly, they look like a cylindrical buLGe at the base of the cable.

Connecting laptop to laptop

Now we can consider a method of how to connect a laptop to a laptop via HDMI. In fact, connecting two laptop computers this way will do nothing. The fact is that the HDMI connector on a laptop is designed only for data transmission, but not for receiving.

For such cases, there is an RJ-45 connector, as well as a Wi-Fi wireless connection. So you can’t connect a laptop to a laptop via HDMI. Some laptops have a built-in Bluetooth adapter that can also be used to connect laptops to each other.

Connecting to a TV without HDMI

It also happens that the laptop does not have the required port, so you have to resort to methods such as an HDMI to laptop adapter. To do this, you need an HDMI cable and a DVI-HDMI adapter.

All operations are carried out exclusively on de-energized equipment. Now you can start connecting. The adapter is inserted into the DVI port on the laptop, and the cable is inserted into the HDMI connector, which is at the output.

After that, you can turn on the TV and laptop. On a laptop, press the right mouse button and select the “Screen Resolution” option. A window with parameters and two screens opens. You need to choose an orientation. landscape, multiple screens. expand these screens, then the “Define” button. This button will help you understand which screen the TV belongs to and which laptop.

After that, you need to select the number to which the TV belongs. most often it is “2”. Then turn on the TV and select the HDMI connection. Now you can broadcast the image and sound from your laptop to your TV.

How to enable HDMI on a laptop: SIMple instructions and recommendations

Nowadays, it is becoming more and more popular to transfer data from one device to another, bypassing portable drives. One such method is an HDMI cable. Here’s how to enable HDMI on a laptop.

The versatility of this type of cable is so popular that it can be used to:

  • Connect TV to Computer.
  • Transfer data from laptop to monitor.
  • Connect smartphone to TV or monitor.
  • Make a connection between the card and the monitor (or TV).
  • Play movies and music using one high quality cable.

It’s getting easier and easier to connect one device to another, which is why HDMI is so popular. Nowadays there are practically no devices that do not have this port. In some cases, you can use adapters, for example, to connect your smartphone to a monitor or TV. Only the image that is broadcast from the source device will be displayed.

For example, if you connect the system unit to a laptop, you will need a card port and a laptop port. The main thing. it is not to mix up the input and output connectors, otherwise the image will not appear.

Diagnosing interface problems

If there are problems with displaying images through this connector, then it is logical to assume that the HDMI port on the laptop is not working. However, you should not rush to conclusions, as there are several “symptoms” of breakdown, which you need to pay attention to.

The first, and most obvious, sign of breakdown will be the disappearance of the image on the TV or monitor. First, it is worth checking the connection, and if the laptop detects it, then it is recommended to inspect the cable. First, it must fit snugly in both slots. Secondly, you need to pay attention to its entire length: are there any kinks, external damage. Thirdly. kind of port. it is often possible to confuse the input / output of the jacks, since several of them are installed, especially in TVs.

Role of the HDMI connector

Before you know how to enable HDMI on a laptop, you need to understand what this connector is for. With it, you can broadcast movies, clips and music. The principle of operation is SIMple. By replacing the analog connection method, HDMI facilitates the transfer of high quality audio from one device to another. This can be a connection from a computer to a TV, from a smartphone to a monitor, and so on. Even cards are connected to the monitor in this way.

Modern versions of the cable are capable of transmitting images in 2K and 4K quality. Unlike its predecessor VGA, this interface does not distort the image and has a higher data transfer rate when the screen is updated at 60 and 120 Hz. And the presence of an audio channel helps to avoid additional audio connection.

Port activation

In most modern devices, where the presence of an HDMI connector is implied, this interface is activated automatically, but in some cases a little adjustment is required. How to enable HDMI on a laptop?

This often happens when a laptop is used as a second monitor for a desktop computer.

To do this, you need an HDMI cable and connect it to the card, and from it you need to connect to the laptop. If one of the devices does not have such an interface, then there is the possibility of using adapters, but then you should prepare for a loss of quality.

Next, you can move on to how to enable HDMI input on a laptop. After the cable has been connected, you can turn on the laptop and wait for the system to boot completely. After that, you need to use the fnF4 key combination. However, on laptops of different models, these may be different keys. This combination activates switching monitors, so you need to look for a key with a screen image.

In the event that this method did not work, then you can use other options. To do this, click the “Start” button and go to the “Control Panel”. Next, you need to select the “Screen” parameter, and in the left column, select the “Configure screen settings” option. This is HDMI setup on laptop.

To find the first display, you need to click on the “Find” button, then set the parameters of the “Expand these screens” pop-up menu. Here’s how to enable HDMI on a laptop.

Interface version

In order to purchase a suitable cable, you need to understand how to find out which HDMI is on your laptop. To do this, you need to consider the characteristics of the card, since it is responsible for this output.

If the card is discrete, then you should visit the manufacturer’s website and view the detailed characteristics of the card, or rather. her outputs. For laptops, this will be seen in their technical specifications.

Solution

If the audio signal is lost, you must visit the “Control Panel” and the “Hardware and Sound” tab. Next, we only need “Sound”, a window will open where you can choose from connection options. If the problem is with a stationary computer, then you need to choose a card, and in the case of a TV, respectively, a TV. After that, click “Apply”.

Do not exclude a problem with the port itself, as it could SIMply burn out. To prevent such a disaster, it is necessary to disconnect extraneous connections before connecting HDMI: cable TV and a satellite dish. It will not be superfluous to check the outlet. its grounding plays an important role. If the connector burns out, contact the service center to replace the connector.

HDMI does not work on a laptop. what to do

First of all, determine what kind of problem arose, because depending on the situation, there are different ways of solving.

General summary

HDMI ports are of different types and versions, each of which requires a suitable cable. For example, you will not be able to connect a device that uses a C-type port (this is the smallest HDMI port) with a standard-sized cable. You will also have difficulties connecting ports with different versions, plus you need to choose a suitable cable for each version. Fortunately, with this point, everything is a little easier, because some versions provide good compatibility with each other. For example, versions 1.2, 1.3, 1.4, 1.4a, 1.4b are fully compatible with each other.

Lesson: How to Choose an HDMI Cable

Before connecting, you need to check the ports and cables for various defects. broken contacts, debris and dust in the connectors, cracks, exposed areas on the cable, flimsy fastening of the port to the device. It will be easy to get rid of some defects; to eliminate others, you will have to take the equipment to a service center or change the cable. Problems such as exposed wires can be hazardous to the health and safety of the owner.

If the versions and types of connectors match each other and the cable, you need to determine the type of problem and solve it in a suitable way.

How to connect a TV to a computer via hdmi in Windows 10: detailed instructions

In the case when Wi-Fi Direct is not configured, Miracast is not supported, there is no flash drive with a large volume, but I really want to watch a movie in good quality, we remember the HDMI connector. a great way to duplicate an image to another device without losing quality. Therefore, the question arises: how to connect a TV to a computer via HDMI in Windows 10 and what is required for this? The answer is below.

How to connect a TV to a laptop via Wi-Fi or HDMI cable in Windows 10?

If you decide to connect your TV to a computer or laptop on Windows 10, then now I will show you and tell you how to do it. We will connect in two ways: via a wireless Wi-Fi network, and using an HDMI cable. Under the Wi-Fi connection, I will enter the connection via a Wi-Fi router, and the DLNA technology setting. When using a computer, you can watch movies, photos, and listen to music on the TV. Well, connecting using an HDMI cable is a normal HDMI connection # 128578; With this connection, our TV will be like a monitor in Windows 10.

Honestly, there is not much difference whether you have Windows 7 or Windows 10. Both the connection to a TV via HDMI and Wi-Fi are practically the same. But, let’s take a look at the example of a laptop with Windows 10 installed. I think this article will be relevant and useful for a long time.

If the sound on the TV does not work when connected to Windows 10 via HDMI

Perhaps, after connecting the TV to the computer, the sound will play not from the TV speakers, but from the laptop speakers, or the connected speakers. This can be easily fixed.

Right-click on the volume control icon in the notification bar and select Playback Devices.

Your TV should be on the list. Right click on it and select Set as default.

Sound will now be heard from your TV speakers.

What to do if HDMI doesn’t work on laptop

HDMI ports are used in almost all modern technology. laptops, TVs, tablets, on-board computers of cars and even in some smartphones. These ports have advantages over many SIMilar connectors (DVI, VGA). HDMI is capable of transmitting sound and SIMultaneously, supports transmission in high quality, is more stable, etc. However, he is not immune from various problems.

Connection instructions

So, to transfer the image to TV, we need to connect two devices using a cable:

  • Turn off your TV and laptop. This must be done so as not to damage the contacts as a result of a possible spark.
  • Connect the ends of the HDMI cable to the input and output connectors (TV and laptop, respectively).
  • Turn on both devices.

Most likely, you will not see the laptop screen projection on the TV.

To do this, TV and PC need to be configured:

  • Enter the TV Menu and find the Input List item. It can also be called up by pressing the “Input” key on the remote control.
  • In the list that appears, click on the input source: HDMI.
  • After that, the image from the computer should appear on the TV.

But if this does not happen, the external signal transmission is disabled on the laptop or PC.

To enable it you need:

  • Press the WinP keys SIMultaneously.
  • In the window that appears, select the type of projection.

The best way is the option “Only the second screen”, in which the image from your car will be accurately copied to the TV screen, while the display of the computer itself will remain off. Choosing a different connection will cause two monitors to work at the same time, which is distracting.

In case your panel has a high resolution display, the transmitted image may be blurry or grainy.

To make full use of your TV screen resources, you need:

  • Right click on the desktop.
  • Select “Screen Options”.
  • In the window that appears, click “Advanced display options”.
  • Then click on “Detect” and after displaying the parameters of the external screen, select the maximum resolution from the drop-down list.

Advice! If you do not have cable TV, and IPTV hits your wallet hard, you can watch TV through a computer: turn on online broadcast or sopcast on a PC and broadcast the image on TV.

Blank desktop appears after connecting to TV

In this case, the problem is not in the HDMI cable or connector, but in the fact that the TV acts as an extension of the laptop screen, that is, it is an additional area of ​​your desktop. In this mode, if you, for example, move any window to the right or left (depending on the settings), you will see it on the TV screen.

In order to switch the display to duplicate mode, in which everything that happens on the laptop screen would be displayed on the TV display, do the following:

  • right-click on an empty area of ​​the desktop;
  • depending on the version of the operating system, select the line “Display settings” or “Screen resolution”;
  • if the TV’s display is not found, click the “Detect” button;
  • find the dropdown menu “Multiple displays”, select the value “Duplicate these screens” and then click “Apply”.

What you need to connect?

To connect, we need:

  • laptop or desktop PC with HDMI output;
  • TV with HDMI input;
  • reversible HDMI cable.

Attention! To get a high-quality picture with an audio track, do not use adapters from HDMI to DVI and VGA, otherwise watching movies and photos will leave only negative emotions.

We connect a laptop to a TV via HDMI cable: tips and tweaks

Updated May 26, 2020

The abbreviation HDMI stands for High Definition Multimedia Interface. That is, a high-definition multimedia interface. Physically represents two devices connected with a cable. In our case, a laptop and TV are connected. Naturally, both of them need HDMI ports. Before you display a laptop screen on a TV, it is worth knowing that there are several versions of the interface, and the technology is constantly evolving. Depending on the version, the interface capabilities change in terms of supported resolutions, bandwidth and other parameters. The last up-to-date version, released at the beginning of 2017, is 2.1.

    • Setting up your TV for HDMI connection

      To switch the TV to the HDMI signal reception mode, you need to explicitly indicate this in the menu. Usually the remote has buttons like Source or Input. In the TV menu, you need to look for items with the name “Signal Source” or “Datsource”. Naturally, the setup must be done after the HDMI cable is connected to the TV and laptop.

      Connecting laptop to TV via HDMI

      There is nothing unusual and complicated in the connection process itself. The only thing, before connecting the laptop to the TV via HDMI, it is advisable to make sure that both versions of the interfaces satisfy the parameters of the transmitted data.

      Laptop does not see HDMI cable from TV

      Such a situation can arise in only two cases: a physical malfunction of the cable or connector and a problem with the card drivers.

      The cable also has its own tensile strength, so it can be damaged. To calculate whether the wire from the laptop to the TV is really damaged, you can try to connect another one. You also need to make sure that the versions are correct and choose the correct cable. With the connector, everything is more difficult, it is rather difficult to establish whether it really is at home. If you just try to switch the cable to another available connector. With the card, everything is easier. it is worth updating the drivers or, conversely, rolling them back to an older version.

      Where is the HDMI input on laptop and TV

      On TVs, the connector can be located either on the back or on the side panel. It is not difficult to determine it, since it is unique, and you will not be able to connect another cable there.

      The connector is usually labeled, so it is easy to find it. HDMI input on a laptop is also not particularly standardized, so it can be anywhere. But most often found on the back of the device.

      How to set up and enable HDMI on a laptop

      If on TV it is enough to SIMply indicate the signal source, then on a PC you sometimes have to tweak the connection a little. Before connecting the laptop to the TV, you can select the display type. Usually by default it will SIMply duplicate the source screen. But other types can be specified as well. In versions of Windows 7 and higher, this can be done by pressing the Win P keys. A window will immediately open in which you can select connection options.

      Calls up the projector connection menu. There are only 4 of them:

      • just a computer. The signal will not be transmitted to TV, but only to the laptop screen;
      • duplicate. The TV screen will be exactly the same as the PC screen;
      • expand. This type adds another screen on which you can separately launch, for example, or open a website, while another application will be used on a laptop;
      • just a projector. The signal will not be repeated on the PC, but will only go to TV.

      TV resolution usually adjusts automatically. But you can also change it manually in the operating system screen settings.

      Setting up audio transmission from laptop to TV

      As we know, HDMI is also capable of transmitting sound. But this does not always happen in practice. In order to switch the sound, you need to refer to the sound settings in the operating system. To do this, you just need to right-click on the speaker icon in the notification bar and select “Playback Devices”.

      Sound menu in the notification bar. A window will open that will display all possible devices capable of outputting sound. Among them, there must be a connected TV. Right-clicking on it and choosing “Use as default”, we will switch the sound to TV.

      Sound settings window.

      What to do if laptop does not connect to TV via HDMI

      Yes, connection problems can arise, but they can and should be dealt with. Consider the two most common cases.

      TV does not see laptop via HDMI

      There may be few reasons why the TV does not see the laptop via HDMI either. The first thing that comes to mind is an incorrectly installed signal source. On some models with 2 or more connectors, you can get confused and choose the wrong one. It is worth checking the correctness of the choice. There is also a possibility that HDMI may not work properly due to Smart TV. The situation is rare, but it does happen. It is worth trying to update the software. In all other cases, suspicion can only fall on the cable or the connector itself.

      Updating the card driver

      If the TV does not see the computer via HDMI, or this connection method has stopped working, then the reason may lie in the card, or rather, in its driver. It may have crashed, the driver is out of date, or it was not installed correctly initially.

      In this case, make sure that the signal does not go due to the old driver on the card, you can do this.

      • On the icon “My computer” or in the explorer on the tab “This computer” RMB should select “Control”.
      • Next “Device Manager”, “Adapters” tab.
      • If there is a failure, then there will be a yellow or red sign opposite the card. They mean that the node is not working properly. If there are no symbols, then the card is working, but the driver may be out of date, and this is a common reason that a number of functions do not work.

      There are several ways to update software for PC components. The most reliable option is to go to the website of the laptop or card manufacturer and download the file for the required operating system, taking into account its bit depth. After installation, the device needs to be rebooted.

      If, after all the above steps, the laptop still does not connect via HDMI to the TV, then the reason is more complex, and you will have to fix it in the workshop. Which device requires a thorough diagnosis, you can find out by trying to connect the TV and PC to other equipment.

      Setting the image output to PC

      If during the check it was concluded that all the connectors and cable are working, but there is still no picture, then it’s time to configure the image output on Windows.

      • A context menu opens on the RMB desktop.
      • “Screen resolution”.
      • “Connecting to a Projector”.
      • Select “Duplicate” to display the picture on both displays or “Projector only”. the desktop will now be visible only on TV.
      • “Start”.
      • “Control Panel”.
      • “Design and personalization”.
      • “Screen”.
      • Multiple Displays. Duplicate or Extend Desktop Only 2.
      • We call “Screen Options”.
      • “DisPlay”.
      • Scroll through the menu to the item “Multiple displays”. If the HDMI cable from the computer to the TV is connected correctly, then a window with a connected second display will be displayed. It should be indicated, the image output method is SIMilar to those mentioned above.

      Checking the health of components

      The most obvious reason why the TV does not see the laptop via HDMI is faulty connectors or wires. It’s easy to check their performance.

      • Try other HDMI inputs on TV.
      • To test the output of the laptop, you can connect it to other equipment.
      • Do not neglect to replace the cable, even if it is new and just purchased.

      In this case, it should be inspected: as a rule, there is an arrow on the plug that must be inserted into the signal source. If there are no arrows, then you can try to connect both ends in turn.

      Adjusting the screen frequency and resolution

      If after that it was still not possible to connect the TV to the computer via HDMI, then the computer settings may not match the TV’s capabilities. It’s about resolution and frequency. If the TV is old, and its resolution is HD, and the system unit is set to FHD by default, then the TV is SIMply not able to display an image. In this case, enter the screen settings according to the instructions above (for each OS version).

      The resolution is set in the same menu where the display method is configured. You must first select the second screen (settings for TV) and in the corresponding menu item set the desired.

      After that, you need to select “Additional display settings”. “Adapter properties for display 2” and specify the frequency. The default is 60 Hz, it makes sense to try smaller parameters.

      Often users receive a message about the collection of the following nature: “HDMI mode is not supported.” On Samsung TVs, this was common a few years ago. It was suggested to “cure” this by switching the resolution and frequency, but later it turned out that this was a factory defect, which was eliminated only by firmware. The problem is typical for older models, modern TVs don’t have it. For those who are faced with this, the only way out is to go to the service center.

      Correct connection of devices

      The best solution to fix something is to do it all over again, but right. Connecting the TV to a computer via HDMI is as follows.

      • One end of the HDMI cable is connected to the corresponding TV socket. Any modern TV has several such outputs, they are numbered, so it is worth remembering which plug is inserted into.
      • The other end is inserted into the corresponding connector of a laptop or computer. In the case of the latter, there can also be several HDMI outputs, while not all of them are active. Choose the one that belongs to the card. it is located next to the VGA or DVI output.
      • On the TV, using the remote control, a menu with signal sources opens and the HDMI connector that was used for synchronization is selected, for example, HDMI.Connecting the system unit to an old TV, you can see that after selecting a signal source, a window appears asking you to specify the type of connected device, you need to select PC or laptop as appropriate.

      If everything is done correctly, then the TV will begin to display the PC desktop, if this did not happen, then it is worth considering other cases of failure.

      Solving problems when connecting a computer to TV via HDMI

      Sometimes it happens that when trying to connect a laptop to a TV via an HDMI cable, the latter says “no signal”, or the screen remains lifeless. This situation cannot be called unique: it happens quite often. The most common cause of a problem lies in the cable, but there are exceptions. For information on how to solve problems when connecting a computer to a TV via HDMI, read the text below.

      Sound setting

      If, when connected, the picture is displayed, but there is no sound, then the problem is either incorrect settings or the use of adapters without an audio interface.

      Configure the sound on the PC as follows.

      • Windows 7.8. Right click on the sound icon in the “playback device” tray, the “playback” tab, select the connected TV and confirm with the “apply” button.
      • Windows 10. RMB in the tray on the sound icon “open sound options”, “sound”, “select an output device”. specify the TV speakers.

      If the problem persists, then we check the volume on both devices, as well as in the player. It will not be superfluous to check and update the driver for the sound card by analogy with how it is done for the card.

      What to do if laptop won’t connect to TV via HDMI

      Connecting a laptop to a TV with HDMI interface, some users fail. Usually, the TV does not display an image or sound track, and there are several reasons for this. As a rule, they can be eliminated without much difficulty by following the recommendations below.

      Problem 1: No signal on the screen, no picture

      So, you have connected the devices with an HDMI cable, but no image appears. In this situation, the following actions are possible:

      • The first step is to check the cable connection both on the TV panel and on the laptop itself. The cable plug must fully fit into the HDMI connector of both devices.
      • Next, check the settings of the TV and the laptop itself. The number of the connected HDMI port is indicated in the TV settings, and the image output method is indicated in the Windows Control Panel. The process of connecting a PC to a TV is described in detail in our other article at the link below. We advise you to follow all the recommendations from there and if the problem reappears, refer to this article again.

      It is possible that the laptop adapter is working with an older driver. It needs to be updated for Full HDMI output to work. Updating software is performed both by built-in Windows functions and by means of third-party programs. For details on how to get the latest driver version, see the link below.

      Problem 2: No sound

      Owners of obsolete notebook models often experience problems with sound output. The image transmitted to the TV without sound may be due to software and hardware incompatibility.

        It is necessary to manually configure the audio device using Windows. This process is described step by step in our separate article.

      We also recommend that you update your sound card software for normal operation of the HDMI interface. This can be accomplished by following the standard driver update steps. Follow the links below to find all the guides you need to know about this topic.

      Owners of Realtek sound cards can use a separate instruction.

      HDMI Audio Channel (ARC) audio support may not be supported by your device. Despite the fact that now almost all devices are equipped with ARC technology, the problem has not remained in the past. The fact is that as soon as the HDMI interface appeared, it only transmitted images. If you are “lucky” to purchase a device where HDMI of the first versions is installed, you will not be able to implement sound transmission in any scenario. In this case, you will need to replace equipment or purchase a special headset.

      Don’t forget that a cable that doesn’t support audio output can also be the culprit. Check the specifications of your TV and laptop to see if the HDMI port works with sound. If there are no complaints about the connectors, you should try to replace the cable with a new one.

      Laptop does not connect to TV via HDMI

      Connection via HDMI is one of the most popular nowadays, because it allows you to transmit sound and image in good quality and as stable as possible. However, when trying to pair a laptop and a TV, the user may have various difficulties, with which we will further help you figure it out. In this article, we will look at the common problems of connecting a laptop to a TV via an HDMI cable.

      Problem 3: Broken connector or cable

      Like any other technique, HDMI controllers or connectors can fail. If the above methods did not bring the desired result:

        Connect another cable. Despite the seeming SIMplicity of buying it, there are several tips and nuances that will make the choice right. In a separate article, we talked in more detail about choosing a device that provides a TV and laptop / PC connection.

      We’ve covered all the different types of malfunctions that occur when transferring a laptop image to a TV. We hope this article was useful enough. In case you encounter technical problems (connector breakage), do not repair yourself!
