How to enable HDMI on a laptop

The HDMI connection transfers multimedia data in good quality and high speed. The transmission of information is carried out through special cables connected to two or more necessary devices. HDMI is the most popular digital interface and has replaced the old analog one. In this article, we will explain in detail everything about this type of connection and analyze how to enable it on a laptop.

The main role of HDMI inputs

The emergence of new digital interfaces such as HDMI contributed to the obsolescence of the previously used popular VGA. He not only transmitted the image with lower quality, but also distorted it, which often caused difficulties in work. The connection in question has a large bandwidth and supports audio transmission.

In addition to HDMI, several other types of digital data transmission interfaces are popular. DVI and DisplayPort. They all have different connectors and some characteristics, which allows you to use the required connection for different situations. Read more about comparing THESE interfaces in our articles on the links below.

Enabling HDMI

It is automatically enabled on all devices that support HDMI connection. Users only need to make a few SIMple settings so that the connection of the two devices is successful, and a clear picture and sound appears on the screen.

Usually, it is enough to change just a few parameters of the operating system and you can immediately start working on the hardware. For detailed instructions on connecting computers and laptops to a monitor via HDMI, see our articles on the links below.

Did this article help you? articles on this topic:

Good afternoon. Tell me, is it possible to use a laptop only as a monitor? THOSE. Connect the laptop to the receiver (Telecard) via HDMI cable, and receive the signal from the receiver to the laptop (as a TV set). Or laptops only work on HDMI “Output” ?

Hello, Alexander. It all depends on the laptop model used. Tell me yours, I will give you the exact answer to the question posed.

My Aser laptop

Alexander, to determine the characteristics you need an exact model of your laptop. The article on the link below tells how to learn it using the example of laptops from ASUS. You can do exactly the same actions.

Hello laptop model Aspire 3
How to connect PS4 to it ?

I have an urgent question Not only to you personally, but to information sites in general.
I am a user who wants to know the answer to 1 single question, how can I connect a ps4 via hdmi to my laptop, I go to your website and start reading stories about what hdmi is, and why is it needed, and when it was Invented, and I throw 5 more articles to enjoy reading very interesting and copied from Wikipedia, and here I am sitting, the chair is already on fire and I turn over 2 pages to get to the cherished words (to find out, read our one more article), and I think, wow, so cool guys came up with, to a SIMple question of what to do, you answer with such useless articles that it’s annoying, you would have 10 times more clients, article views, etc. If you just wrote 3 points in the center in black and bold type (or more, less, does not play a role, this is according to the situation), how to do it.

Dear Anonymous, instead of writing canvases with unreasonable criticism and accusations of copy-paste, you would normally use the search (like Google or Yandex, and the search specifically on our website, which was the direct case here of the comment input field), correctly formulating your request. Here is an article for you on a topic of interest, not thanks. the link below. And it was written by the author himself, and not stolen from. Wikipedia, which, if anything, in theory, not work. So, hopefully, your chair will cool down as soon as you successfully follow the link (it is a couple of terms below) and just read the article. Well, and less negative, please, because users who come to the site actually read articles on topics of interest to them, ask questions, if any, and do not resent the articles, and not related to their problem.

I have such a question. I reviewed a bunch of information ands anywhere I can not understand. I have a laptop. It already has an HDMI input. I connect via HDMI, PS4. The question is how to enable this HDMI. In the sense of which button to press or what to do? For example, on a TV. I turned it on. I selected the HDMI 3 port in the menu and you play. And how to do this in a laptop? Tell me please

Hello Dmitry. If you connect a laptop to PS4, the screen should automatically switch, or a separate function key on the laptop, for example, Fn F4, is responsible for this. In addition, to connect to PS4, you must have HDMI-In installed. Read more about this in our other material on this topic.

Hey. I have a Samsung laptop and there is just some kind of rubber plug instead of the hdmi connector. I can’t take it off, how to do it?

Hello Anatoly. If your laptop model has a plug instead of the HDMI connector, then it does not support connection through this interface and you do not need to try to pull it out. The fact is that such plugs were previously installed in the younger models of laptops of the same series, which were NOT designed to work via HDMI. If you want to display the image on the monitor, then you should use a special VGA to HDMI adapter, since the laptop used must definitely have VGA on board. It is desirable that it be an active converter with additional power, it is connected via USB. In addition, pay attention when buying that it was VGA to HDMI, and not vice versa.

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.

Problem 2: sound is NOT transmitted

HDMI integrates ARC technology, which allows audio to be transmitted along with content to a TV or monitor. Unfortunately, the sound does not always start to be transmitted immediately, since to connect it, you need to make some settings in the operating system, update the sound card drivers.

In the first versions of HDMI, there was no built-in support for ARC technology, so if you have an outdated cable and / or connector, then to connect the sound you will either have to replace the ports / cables, or together a special headset. Audio support was first added in HDMI version 1.2. And cables manufactured before 2010 have problems with sound reproduction, that is, it may be broadcast, but its quality is poor.

Lesson: How to connect audio on TV via HDMI

Problems connecting a laptop to another device via HDMI are common, but many are easy to fix. If they cannot be solved, then most likely it will be necessary to change or repair ports and / or cables, as there is a high risk that they are damaged.

We are glad that We were able to help you in solving the problem.

Image is transmitted but there is no sound

In this case, you just need to correctly send the sound signal. This can be done in the following way:

  • Open “Control Panel” and select the “Hardware and Sound” category;
  • Go to the “Sound” section;
  • In the “Playback” tab, depending on the configuration, select your card or TV, and then click “Apply”.

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 not play 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 the playback device.

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

Now the sound will be heard from your TV speakers.

Connect your TV to your laptop (Windows 10) via Wi-Fi. DLNA setup

We will NOT consider setting up Wi-Fi Direct technology (when you can connect a TV to a laptop without a router, wirelessly) and Miracast (not all devices support this technology). These are topics for SEPARATE articles.

If you want to connect your TV to your computer wirelessly, you can do this as follows:

The main thing is that the laptop and the TV are connected to the same router. By the way, not necessarily via Wi-Fi. One of the devices (or even both) can be connected to the router via cable.

After you connect everything, you can proceed to setting up the DLNA server on your computer. I started the server on my computer, I can watch movies on the TV Please note that the TV will not display the desktop when using this method. You will only be able to View specific files. On setting up a DLNA server, we have three articles:

Despite the fact that they are written on the example of Windows 7, on Windows 10 the DLNA server setup will be the same. I checked, Launched on a laptop with Windows 10 installed, the DLNA server is displayed without problems on the TV.

I have instructions on the links above for LG and Philips TVs. But, the server launched in the above described ways will work without problems on second TVs: Samsung, Sony, Toshiba, etc. Set up DLNA using the “Home Media Server (UPnP, DLNA, HTTP)” program (As I did in (See article for Philips TV). It can be called universal.

With the wireless connection, I think sorted out. Moving on to the wires.

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 from 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.

To be honest, there is a big difference whether you have Windows 7 or Windows 10. Connecting to a TV via HDMI or Wi-Fi is practically the same. But, let’s take a look at the example of a laptop with Windows 10. I think this article will be relevant and useful for a long time.

Blank desktop is displayed after connecting to TV

In this case, the problem is not in the cable or the HDMI connector, but in the fact that the TV acts as an extension of the laptop screen, i.e. 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 the duplication 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 term “Display settings” or “Screen resolution”;
  • If the TV display is not found, click the “detect” button;
  • Find the dropdown menu “Multiple displays”, select “Duplicate these screens” and then click “Apply”.

The laptop sees the connection, but there is a corresponding picture on the TV display

First, check the reliability of the connection, the HDMI cable should NOT hang out in the socket of the TV or laptop. Then carefully inspect the HDMI wire, if you find kinks or damage, think about replacing the wire, perhaps this way you will solve the problem.

If everything is okay with the manual, then make sure you select the correct jack when connecting to your TV. The fact is that some TV models have multiple HDMI ports, and by default, the settings set to receive a signal from only one of them.

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) using 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 K. 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 connector, cracks, exposed areas on the cable, flimsy fastening of the port to the device. Some defects can be easily eliminated; to eliminate the second, 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 enable correctly?

The best way to fix the problem and the concept of what is wrong is to do it all over again.

  • Gently insert one end of the cable into a laptop or computer and the other into an HDMI port on a TV or other device.
  • In any free field of the desktop, right-click and select the desired section.
  • Under the screen with the number. select the second item.
  • Next, we are offered several options. For displaying the monitor screen, it is better to choose the first or fourth option. After that, click “Apply”.

For faster activation of the display mode and screen mirroring, you can SIMultaneously press two keys “Win” (located between the keys “Ctrl” and “Alt”) and the English button “P”. After that, just select the mode. Just don’t mix it up. you need to click on the English letter.

Sun sound

  • First, let’s check if audio is being output to the second device. Let me remind you that a cable of this format should calmly output both sound and image on the screen. Click “Start” and then enter the word “Sound” in the search term. Next, select this section.
  • Go to the “Playback” tab. Now you should see the name of your TV there with the words “TV”. Right-click and select “Use this device as default.” Don’t forget to click “Apply”. If there is still sound, go to the next chapter.

HDMI stopped working on laptop: how to check and enable

I bought myself a TV quite recently and somehow before there was no need to use an HDMI cable at all. But then the relatives came home. And I decided to show the photo as well. We plug in the cable, but there is no picture and no sound either. In general, Beals I have with this problem, but still managed to solve it. Today I will tell you why HDMI does not work on a laptop and how to solve this problem.

And so, first of all, look at the integrity of the cable. A friend of mine had a cat, so he bit through the wire from the XBox and he could not understand for a long time why there was no picture. They rarely burn, but nevertheless it is worth checking for this. Now we go to the settings. The configuration will be the same for all Windows versions: 10, 8, 7, etc.

Installing drivers and checking

And so, let me remind you that the HDMI output goes directly from the card. No difference built-in or stand-alone. Our task is to install newer drivers.

  • We press SIMultaneously on two keys “WinR”. Next, we write the command as above in the picture.
  • Go to the “adapters” section. Click on our card with the right button and then “Update drivers.”.
  • We immediately select the first item and wait while the system finds a new driver on Microsoft servers. If the driver is found, install it. But it is not always possible to update the software this way. Sometimes the system does NOT find anything and you see a message that the driver does not need to be updated. In fact, he just didn’t find the Ego.
  • To install the exact driver, you need to find out the name of your card. As you might have noticed, the name is displayed there in the “Device Manager”. Then just enter it into the search engine and download the driver from the official website.
  • Don’t forget to specify the operating system. We download only the latest driver and the full package. After downloading, Install and reboot the device.

If this does not help and there are still images on the TV, then try a different port on the TV and on the laptop (if available). Otherwise, you need to take some other wire, perhaps the one you are using broken or not compatible by standards. The cable can be tested by connecting another laptop or computer to it.

HDMI Troubleshooting Tips

  • Check if the cable is connected correctly: If HDMI does not work, then, first of all, see if the connectors on the ends of the cable have come off the pins in the jacks. In most systems, the cable is not very tight and can easily come off. If this turns into an ongoing problem, consider how to secure the HDMI cable.
  • Try to turn on the devices in a different sequence: In other words, if you always turn on the TV first, and then the Blu-ray disc player (or other signal source), then when faced with a problem, try changing your habit and turn on the player first. If your home theater has three or more components, try different sequencing options. After finding the sequence that led to a positive result, remember it.
  • If your devices have multiple HDMI inputs or outputs, test each one in a different power-up sequence.
  • Check the resolution settings of the signal on the source: It is best to set the automatic resolution in the settings of the source device. You can also try to change the resolution on your TV and find one that works.
  • Use the exclusion method: If the previous steps did not allow you to find out why HDMI does not work, then in complex systems (for example, the signal from the player is transmitted to the home theater, and then to the TV), exclude components that can be dispensed with (in the example. home theater). Connect your Blu-ray disc player directly to your TV. If everything worked, then the excluded component is the culprit. In the example, you can send the signal directly (via HDMI), and the sound can be fed to the home theater with a separate cable. This is not the most elegant solution, but it can be used as a temporary measure, until the problem with Home Theater is fixed.
  • If none of the above techniques gave the expected effect, and you still do not understand why HDMI does not work, then update the firmware of all devices (player, receiver, home theater and even TV).
  • You can also read thematic forums on the Internet. Someone may have already faced a SIMilar problem and found a solution.

Why HDMI does not work: aLGorithm for solving the problem

Most home systems today are for playback. Including high-definition plasma TVs, projectors, Blu-ray players, network media players, satellite receivers and the like, HDMI is used for signal transmission. This protocol was developed to facilitate the transmission of high-quality signal and sound.

It also features HDCP copy protection. Components connected via HDMI Must be able to recognize each other and exchange service information. The latter is often referred to as the “HDMI handshake”. If you are trying to understand why HDMI is not working, then it is quite possible that one of the devices may not be able to recognize the HDCP overhead information sent to it by the second component. As a result, we see nothing on the TV screen.

Faced with the problem of connecting devices via HDMI, I recommend checking a few SIMple things, which, with a high degree of probability, will help you.

Connecting laptop / computer to TV via HDMI does not work

and more users are starting to use a computer or laptop as a signal source. Problems can arise here as well. If you cannot connect your laptop / PC to the TV, then check in the system settings if HDMI is used as an output. and audio signal. If you still do not understand why HDMI does not work in a computer-TV connection, then try the following:

  • Connect the TV and computer with a cable, and then restart the last.
  • Try turning on or restarting your laptop or computer and then turning on the TV.
  • If this did not work, then turn on the computer, then turn on the TV, and after that. connect them with an HDMI cable.
  • If this does not help, then transmit the signal from the computer to the TV through the VGA output (if the TV has such an input).

Troubleshooting HDMI-DVI or DVI-HDMI connection problems

It is often difficult to connect two devices, one of which has an HDMI port and the other has a DVI port. This uses an HDMI-DVI adapter cable or a separate HDMI-DVI adapter located at one end of the DVI or HDMI cable. In addition, a device with a DVI port must be HDCP compliant. This is a prerequisite for pairing two devices.

Also remember that if HDMI can transmit sound and. Then DVI is for signal only. This means that you will have to use an additional cable to transmit sound.

  • In most cases, HDMI-DVI is transmitted without problems. If the transmission does not work, then the most likely prerequisite is the transfer
    porch. If you try several models, then the question may be resolved by itself.
  • However, if your TV is old enough, its DVI port may NOT support HDCP. In this situation, try downloading and installing the latest firmware. It is also worth trying to transmit the signal from this source to another receiver. Possibly the problem is with the player, laptop or receiver.
HDMI Does Not Work On Laptop

Remarks

In the vast majority of cases, the signal transmission problem is associated with an insufficiently reliable connection between the HDMI cable pins and the jack. But the reason may be more complex. If you are faced with a problem with the HDMI connection, then do not panic, but carefully read the above recommendations, and you should have everything working.

Well, if this does not help, then contact the technical support service of the purchased devices for help. If this did NOT solve the problem, then you are faced with a warranty case. contact the seller.

And yet, if you are used to “looking to the future”, then immediately get an HDMI cable with a bandwidth of 10.2 Gbps. It won’t be a big deal today, but when TVs and 4K sources fall in price, this cable will come in handy.

What to do first?

First, you need to determine what caused the problem, since the ways to solve it may differ depending on the situation.

A common phenomenon is that HDMI does not work on a Windows laptop, that is, after the connection has been made, you only see an empty desktop on the screen. The problem here is not the connector or the cable. The fact is that the TV here acts as an extension of the laptop screen, i.e. It becomes an additional area of ​​the desktop. To see the window in this situation, it will be enough just to move it to the left or right.

This is not enough for correct operation, so you need to switch the display in full duplicate desktop mode. To do this, proceed as follows:

  • Right-click on an empty area of ​​the desktop;
  • Next, select the item screen parameters (or screen resolution. depending on the OS);
  • If the device does not see the TV display, then select the “detect” item;
  • Next, you need to find a drop-down menu and there you will also find the item “duplicate screens”.

How to enable HDMI on a laptop

In recent years, the HDMI connector has gained more and more popularity because, unlike other ports, it has the ability to carry audio. Absolutely all laptops are equipped with such a connector, thanks to which you can easily connect to a TV and display the image on a large screen. Consider what you can do if HDMI does not work on a laptop, depending on the situation.

If the HDMI output on the laptop does not work, this method will help fix the problem.

The laptop sees the connection, but there is no picture on the TV display. First of all, you need to check the connection. The wire must sit firmly, carefully inspect it for damage and kinks. If they are present, the cable will have to be replaced.

If everything is in order with the cable, there is damage, then you need to check whether the correct socket was selected. Often TVs have several ports at the same time, but the signal reception in the settings is set to only one port.

Everything is fine with the picture, but there is no sound. In this situation, your task is to send the audio signal correctly. To do this, do the following:

  • In the “Control Panel” select the “Hardware and Sound” section;
  • Next, go to the category called “Sound”;
  • In the “Playback” tab, depending on the settings, I select a TV or card, click “Apply”.

If HDMI stopped working on a laptop, while all the above steps did not help in any way, then you should check if the port itself is in working order. Sometimes they burn out. of course, you have to carry the laptop to a service center. To avoid such a problem, it is imperative to disconnect the cable and satellite dish from the TV before connecting. If the outlet that supplies power is not grounded, disconnect power from all devices before connecting.

It is worth noting that troubles of this kind can appear both with the TV port and with the laptop connector. To find out exactly where the problem lies, connect another gadget using HDMI. If you find a problem with one of the devices, it is best to seek professional help.

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 in 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.

Problem 1: the image is NOT displayed on TV

When connecting a computer and a TV, the image may not always be output immediately, sometimes you need to do some settings. Also, the problem may be in the TV, virus infection of the computer, outdated card drivers.

Consider the instructions for carrying out standard screen settings for a laptop and computer, which will allow you to configure the display of images on TV:

    Right-click on any empty area of ​​the desktop. A special menu will appear, from which you need to go to “Display Settings” for Windows 10 or “Screen Resolution” for earlier OS versions.

Next, you will have to click “find” or “Find” (depending on the OS version), so that the control panel finds a TV or monitor, which is already connected via HDMI. The required button is either under the window, where the display with the number 1 is schematically shown, or the case from it.

  • In the “Display Manager” window that opens, you need to find and connect the TV (there should be an icon with the TV caption). Click on it. If it does not appear, then check again that the cables are connected correctly. Provided that everything is fine, a SIMilar image of the 2nd screen will appear next to the schematic image of the 1st screen.
  • Select the options for displaying the image on two screens. There are three of them: “Duplication”, that is, the same picture is displayed both on the computer display and on the TV; “Extend the desktop” implies the creation of a single workspace on two screens; “Display desktop 1: 2”, this option implies transferring the image to only one of the monitors.
  • Setting up the display does not always guarantee that everything will work 100%, because. The problem may lie in other components of the computer or in the TV itself.

    Problem 2: sound is NOT transmitted

    HDMI integrates ARC technology, which allows audio to be transmitted along with content to a TV or monitor. Unfortunately, the sound does not always start to be transmitted immediately, since to connect it, you need to make some settings in the operating system, update the sound card drivers.
