• How to enable hdmi output on a computer. Connecting a TV to a computer and laptop via HDMI

    The topic of the conversation should rather have been called “How to connect a TV to a computer via HDMI.” Most beginners do the procedure incorrectly, asking questions that are difficult for a professional to answer. Recall: HDMI is recognized as high-performance digital interface transmission of media content. Images, music, other entertainment content. It will be possible to listen to music from a TV or home theater. The HDMI port was invented as a high-performance means of transmitting information. Let's find out why the TV doesn't see HDMI and how to fix it.

    Connecting a TV to a Computer HDMI

    Correctly connecting the TV using HDMI

    Home theater owners should know the truth - a digital media device has a playback source menu. The easiest way to illustrate the fact is with old music centers. Traditionally, devices had three blocks:

    1. Cassette decks: recording, playback.
    2. Radio broadcast reception.
    3. Laser discs.

    Moreover, the blocks refused to play melodies simultaneously. It was necessary to switch sections using a special lever. Even modern phone often equipped with an FM button... Can't figure out why the TV doesn't see HDMI? Let's move on. Rear panel A TV usually contains half a dozen output jacks. Among the troops we will find a “tulip” formed by three petals, sometimes VGA puffs up, and certainly HDMI. Traditionally, the list is not limited to a meager list; see the instructions for more details. From the remote control, with the elusive press of a button (with only one HDMI port), you can select a source from the menu. The selection tool can be the Source key. You need to find a menu listing sources, select the cable connection port. HDMI connectors There may be more than two, it is important to track the number correctly.

    The computer usually avoids such tricks. There is no direct option to select the direction of signal transmission. However:

    • On laptops, the function keys Fn+F3 (F4) will open the pop-up system menu, listing interesting options:
    1. Computer only. Image to external monitor(TV) will not work. Most people choose the named option. Don't be surprised that the TV can't see the laptop.
    2. Duplicate. The laptop screen will be duplicated by the TV. This is what most people need.
    3. Expand. Some people like to drag player and browser windows onto the TV, making it more convenient to watch movies. Let's be afraid to judge (tastes are individual), select the Expand option, lengthening the desktop.
    4. Projector only. The laptop screen turns off. The image will be displayed individually on the TV.
    • Desktop personal computers detect TV independently. Otherwise, take the trouble to visit the driver menu and select the required broadcast port.

    It is easier to control a connected TV using the desktop context menu. First right click free space, select the Screen Resolution option. Successful TV detection makes the “Multiple Monitors” button available. You will see four options that are exactly the same as the laptop options. Read the values ​​above. It happens that the computer does not see the TV via HDMI: it makes sense to look here and take a look context menu. The monitors will be numbered; you can swap ports by simply clicking and selecting the object for changing system parameters.

    There is no “Multiple Monitors” button in case of inconsistency: the system does not see the TV. Both devices must be turned on (230 volt power supply).

    We connect the TV and computer with a cable

    Pros say: it is possible to hot-connect a TV and computer via HDMI. Avoid risking expensive equipment; perform procedures in the absence of power. The first thing you need to do is turn on the TV. In normal mode, devices see each other. Problems mean there is a breakdown. Is hot plugging possible or not?

    Here is the Wikipedia page http://en.wikipedia.org/wiki/HDMI, in the characteristics of the standard there is the phrase Hot Pluggable: Yes. Translating into Russian, we see the docking of the connectors with the power on. Want to play it safe? Russia is a place where dealers and manufacturers comply with regulations selectively. It's a pity for the equipment - play it safe.

    Which end should you start connecting the cable to? No difference.

    Sound. Connecting a TV to a Computer HDMI

    Since its creation by the committee (2002), the HDMI interface has been conceived as a combined solution for transmitting image and sound. See the available audio formats individually (Wikipedia page), we only note that in Windows you need to select the sound source. Now the TV is being viewed system device, therefore these responsibilities can be assigned to him. To do this, it’s easier to right-click the lower right corner of the desktop (speaker icon) and select Playback devices in the context menu. If there is no icon in the lower right corner, you need to click the arrow to the right of the language selection symbol RU (EN), to the left of the clock. There will be a symbol there.

    After clicking, a window will open: playback devices will be listed. You will need to turn off everything except the TV, and, on the contrary, turn on the TV. In 90% of cases, after a couple of seconds the native speakers of the plasma panel will sound. Do we want Sound Around? Similar speaker system comes with home theater. Look through the device description. There are a number of ways to transfer sound from a TV to a home theater; any will do, taking into account the need to purchase the required cable. Similarly, using the Source button on the home theater control panel, select the desired sound source.

    On the TV side, the procedure is often transparent, and the device’s own speakers are turned off. Then don't worry if the movie soundtrack is recorded in mono. Every self-respecting home theater has a splitter inside that easily splits the sound into channels of the Sound Around format.

    FAQ: Connecting a TV to a Computer HDMI

    • The TV does not see the HDMI cable. What to do?

    We would venture a guess: the TV playback source is incorrectly specified. Check that the computer's Target signal is correct. For TV, use the remote control. Using the menu or the Source or Hdmi keys, ensure that the source exactly matches the socket where the wire is inserted. For example, if this is HDMI 3, then you need to put HDMI 3 in the menu. From the laptop side function key Fn+F3 or F4 (on different models differently) select the Duplicate mode.

    PC connection

    Get comfortable first, then change as you see fit. A similar action is performed on a desktop computer, through the desktop context menu (the “Change resolution” column), both devices must be turned on.

    • There is no sound on the TV through the HDMI cable, but there is an image, what should I do?

    The audio stream output device is set incorrectly personal computer. Click the speaker icon (bottom right of the screen). Fix the problem by clicking Playback Devices. In the window that opens, turn off playback devices, excluding TV speakers. If necessary, also make the instance active (the line will turn green).

    • The TV stopped seeing HDMI.

    We would venture to guess that the breakdown was preceded by a change of equipment. Installed new video map. Seeing this outcome, the TV could reset its settings. Start over. The guidelines are provided above. Check the signal source and destination. Any parameters related to sound, image.

    • The laptop does not see the TV via HDMI.

    You need to choose the right TV signal output source. Switched on devices must see each other. There is information that the cables different versions standards are incompatible with the equipment. If v1.3 was present, the equipment worked; replacing v1.4 caused the picture to disappear. Sometimes setting up a video card requires adding a second monitor manually. Relevant for desktop computers.

    You see: there are few reasons (the TV does not see HDMI). Mainly setting up equipment. Experts recommend installing new TV firmware, then turning off the device, pause for 5 minutes. It is permissible to reboot the product manually (the menu will help), for each model the exact sequence of actions is different: LG, Sony, Samsung - the device demonstrates its features. Proceed according to the instructions. Farewell advice. Be sure to try the TV ports one by one, changing the image source through the menu. There were cases where out of four HDMI sockets, the only one that worked, for example, the fourth one. If we watch films, it makes no difference, number 1, 2, 3...

    Readers should understand that the Windows operating system is not perfect. To make the equipment work, you have to reboot the devices several times. It happens that pros ask why digital technology failed? The master shrugs his shoulders, says Windows - Must Die, Linux - well done. It’s difficult to say what the phrase means, but for some reason the difficulties on the forums relate specifically to the paid operating system, and not to the freely distributed one. We see no point in discussing further.

    But in that article we looked at everything possible ways connections from the most ancient interfaces (VGA, tulips) to the most modern HDMI. But times are changing and today HDMI is the most advanced interface that is present in all modern TVs and which is used most often. Therefore, today we will dwell on this in more detail. Let's figure out the connection, as well as possible problems.

    So, how to connect your TV to your computer via HDMI?

    The first thing we need is to make sure there is this interface on both devices - TV and computer (or laptop), it looks like this:

    Prices for them vary greatly, both from the length of the cable itself and from the quality of workmanship (the material from which it is made, etc.). I took the cheapest 3.3 meter cable (price about $4) and it shows everything perfectly, even high-resolution files - it shows 1080p without any jambs. Now decide for yourself which cable to take. And of course, don’t forget about the length so that it’s not too short.

    We connect this cable to the computer (laptop) and to the TV. Typically in LCD TVs some HDMI inputs— connect to anyone, there’s not much difference. And on the TV we select the HDMI source. Samsung has something for this separate button HDMI or click SOURCE (other manufacturers should have something similar):

    and select the desired source depending on which socket number you inserted into, and select that one:

    Next, we'll look at setting up the computer.

    If you connect your TV to your computer as the main monitor, then it should be automatically detected. If you connect your TV as an additional monitor, then most likely you will have to configure something. As a rule, there are no problems, everything is quite simple and quick to set up, the system is still more modern, but it doesn’t always work out so smoothly. But now let's try to figure it out for different versions of operating systems.

    So, setup for Windows 7

    Right-click on the desktop and select “Screen Resolution”:

    The following window will appear:

    And here, in the “Multiple Screens” field, select the mode you need. You can either duplicate the image on both the main and additional monitors (TV) or Expand, that is, in other words, enlarge the screen on the right side, or leave only one of the screens active. Here, select all the modes one by one and see what’s what. And after you select desired mode, click “Apply” for the changes to take effect, and then confirm your action again by clicking “Save Changes” in the pop-up window:

    For laptops Windows control 7 is still easier. To select the appropriate display mode, you just need to press the key combination Fn+F4 (perhaps in some models it will not be F4, but another button, the main thing is to make sure that something like a monitor is shown, as in the screenshot below, there may also be other symbols or slightly different picture):

    After pressing these key combinations you will see the following window:

    And alternately pressing F4, while holding Fn, select the desired mode.

    This seems to have been sorted out. Here, in principle, no problems should arise, but with Windows XP, as I already said, everything is not so simple. Firstly, in the case of a laptop, XP simply does not understand the Fn+F4 key combination, I don’t know why, but I couldn’t make friends with these “hot” keys in Windows. Secondly, in the case of a computer, it is also not always possible to configure an additional screen (in our case, a TV) through the screen settings, so you have to get into even greater depths. But, hopeless situations doesn’t happen, so now we’ll look at how to solve the problem of connecting a TV to a computer running Windows XP.

    Setting up a connection for Windows XP

    First, we try to configure the connection through the screen settings. Right-click on the desktop and select “Properties”, and then go to the “Options” tab:

    And in this window, you can select your TV as the main screen by selecting screen 2 and checking the box next to “Use this device as the main” or you can Extend the desktop by selecting the appropriate option below. Then click “Apply”. And close this window. But, unfortunately, it is not always possible to configure the connection between the TV and the computer this way. And if nothing works out for you, move on.

    If all of the above methods do not suit you, then the only option left is to configure the connection through the utility of your video card. And here, unfortunately, I won’t tell you a single recipe, since everyone has their own hardware, some have Intel, some have Nvidia, some have Radeon, some have a newer video card, some have an older one, Accordingly, these utilities will be different, but the principle is very similar, only the exact name will differ, and general meaning naturally it will be the same. I'll show you Nvidia example, but I will repeat for others - all actions are similar.

    So, right-click on the desktop and select “NVIDIA Control Panel”:

    And in the window that opens, click on the plus next to the “Display” item to expand the entire contents of the section and go to the “Installing multiple displays” item:

    and in the right part of the window, select the desired mode and click “Apply”. If one of them does not work, choose another. As a rule, the "Clone" mode works without problems.

    Well, that's all. I told everything I could. If you still can’t connect your TV to your computer via HDMI, then ask in the comments, I’ll try to give you some practical advice.

    In case Wi-Fi Direct is not configured, Miracast is not supported, there is no flash drive with a large capacity, and the movie is in good quality I really want to see it, 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.

    What do 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 only leave negative emotions.

    Connection instructions

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


    Chances are you won't see your laptop screen projected onto your TV.

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


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

    To enable it you need:

    The best way is the “Second Screen Only” option, in which the image from your machine will be accurately copied onto the TV screen, while the computer display itself will remain turned off. Selecting a different connection will result in two monitors running at the same time, which has a distracting effect.

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

    To fully utilize the resources of your TV screen, you need:


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

    A pressing problem for many users today is expanding the image from a personal computer to a home plasma display. “We connect the TV to the computer via HDMI, but there is no image,” - this is exactly how negative sounds come from the mouths of computer equipment owners.

    In this article, the reader will become acquainted not only with the method of connecting an additional display to a PC or laptop, but will also learn about correct settings equipment. He will also be interested in recommendations from experts in the field of IT technologies.

    About the goals pursued

    The larger the diagonal of the LCD screen, the more comfortable viewing multimedia and better image detail in games and software. A film on a TV from a computer will allow you to see the smallest details, and a fan of a dynamic toy will feel the reality of the events taking place on the plasma screen. In fact, there are many advantages of using such a symbiosis, and all of them relate to the comfortable work or leisure of the user.

    In recent years, many users have become interested in Internet television. Why pay money to the provider if you can watch your favorite channels for free from the official website of the television company? Therefore, the question is: “How to connect a computer to a TV?” sounds more and more often in the media. But so far things are going badly with ready-made solutions.

    Computer hardware capabilities

    It's better to start with technical capabilities personal computer or laptop. The fact is that it is not enough to buy an HDMI cable for your computer. It will be possible to connect to the TV only if there is an appropriate digital video output on the PC. Therefore, the user needs to familiarize himself with all the outputs of the system unit and find the desired port. It can be located on the video card or on motherboard at the computer and at one of the ends of the mobile laptop.

    There are devices that do not have an HDMI connector. It is quite possible to find a VGA (D-Sub) or video output on old digital ports DVI with DisplayPort. Here everything depends on to a greater extent from the TV, which should have similar inputs. Having picked up required cable for TV, you will always find the opportunity to display the image from the computer.

    TV availability

    But modern liquid crystal devices with HDMI ports have no problems - all manufacturers provide their equipment with a popular interface. Often they are not limited to one port at the factory and provide the user with the opportunity to connect several sources to output images via HDMI.

    Liquid crystal displays large sizes have a slightly different problem. We are talking about the resolution of the reproduced image and the frame rate. Before connecting a computer and TV via HDMI, the user needs to familiarize himself with technical characteristics both devices, compare their video signal transmission capabilities and find a parameter that will be supported by both plasma and PC. Often, all equipment manufacturers strive to ensure that equipment supports FullHD resolution (1920x1080) at a frequency of 60 Hz. True, there are exceptions that create problems for users.

    Operation of devices of different generations

    In situations involving connecting two devices with different interfaces (HDMI, VGA), users are often surprised why the computer does not see the TV via HDMI. The explanation is simple - it is impossible to connect the equipment different generations, combining analog and digital signals with one cable. In such situations, no adapter will solve the problem - you need a converter that can decode the signal at the hardware level.

    Fortunately, they are present at foreign auctions ready-made solutions, which are able to solve all the problems of users with video signal transmission between devices of different generations. The cost of one converter is in the range of 20-30 USD. That is, which attracts a potential buyer. All the necessary cables for video transmission are always included with the converter, so the algorithm for solving the problem is simple: buy a converter and connect the TV to the computer via HDMI.

    When the required interface is not available

    Not all computers and TVs have an HDMI port - that's a fact. But you shouldn’t get upset ahead of time, because morally outdated devices the problem can always be solved. The fact is that old equipment is geared towards transmitting analog signal. Let by image quality this technology and lags behind, however with compatibility different standards She has an order of magnitude fewer problems. Combining S-Vidio, VGA or RCA interfaces is much easier than converting to digital.

    The user just needs to buy a cable for the TV and connect both devices. There are also many inconveniences that users will have to face. Firstly, audio cannot be transmitted over an interface cable. Accordingly, you need to buy another cable. Secondly, during operation, the sound card of a computer or laptop will not be able to create an individual audio stream for the TV. Accordingly, about the amenities sharing You can forget about the computer and TV.

    The right approach to buying a cable

    Problems may arise for the user when choosing wrong cable HDMI. The fact is that a digital video signal is not capable of being transmitted over long distances via cable without loss of quality. Therefore, the future owner needs to decide on the length before buying an HDMI cable for a computer to a TV.

    The main thing is to always remember that the longer the quality cable, the higher its cost. It is necessary to measure the distance between the PC and the liquid crystal display (of course, not in line of sight, but taking into account the installation) and find a cable of the appropriate length on the market. Yes, it is customary for buyers to purchase wires with a reserve, but it should be small, since often the excess is rarely in demand - more often they just collect dust behind the TV or behind the computer. The main thing here is to find golden mean according to the ratio “cost - cable length”.

    Real offers from manufacturers

    It is not easy to choose a cable for a TV of the HDMI-HDMI form factor on the market. Any buyer can verify this for himself; just look at the prices and assortment. It is logical to assume that expensive accessories have a high price only because they are made by serious brands. There is truth to this, but as a rule of thumb, the more expensive the HDMI cable, the less likely it is that the video signal will deteriorate over a long distance. In fact, you have to pay for quality. Chinese consumer goods have no place in the domestic market.

    IT experts recommend paying attention to the brand name (for example, Prolink, Cablexpert, Viewcon, Belkin), as well as focusing on the quality of the winding and the presence of ferrite filters near the connectors (barrels near the contacts). If an HDMI cable is required, the length of which exceeds 30 meters, then the user cannot do without a signal amplifier. The device is expensive, but copes with the assigned tasks 100%.

    Physical connection of two devices

    This article is not about potential difference from a school physics course, but the user still needs to know that there is a small amount of voltage on the video ports when the equipment is plugged into the mains. electric charge. Naturally, when connecting two devices, equipment with a large charge will transfer energy through the cable to the port of the connected device. Often the TV turns out to be more powerful, which, when connected, burns the output on the computer’s video card. Therefore, before connecting your computer to the TV via HDMI, you need to turn off the power to one of the devices (unplug the plug from the socket). Naturally, this problem bypasses all users who have grounding in their house.

    Another problem that the buyer may encounter is the lack of a video signal when connecting the cable or the image transmission with noise. There is no need to touch the settings of your TV or computer - 99% of the time the problem is a low-quality cable. It needs to be replaced. In general, experts recommend checking the HDMI cable directly in the store to avoid connection problems.

    TV settings

    It will not be difficult for the owner of a liquid crystal display to remote control device, press the “Source” button and select the desired signal source. All ports on the TV panel are registered and numbered, so all that remains is to combine software part from the hardware room. Don't expect the PC image to appear on the screen right away. The main thing here is to get the display ready to receive a video signal. This will complete the setup of connecting the TV to the computer via HDMI. All that remains is to configure the video output of your PC or laptop.

    Many users are owners of home theaters and other video and audio equipment that is connected to an LCD TV. Naturally, a situation may arise when everything HDMI ports busy. Many users are unlikely to want to physically rearrange the HDMI cable when working with a computer, so another solution is proposed. The video signal from the laptop can be transmitted to a tuner or receiver. In fact, there is no difference, since manufacturers use a single standard for transmitting images via HDMI.

    Modern platforms

    When it comes to the Windows 10 or MacOS operating systems, there are practically no configuration issues. The user only needs to restart the computer for the device to detect and connect new display. How more modern technology, the more efficiently it happens automatic setting- often via HDMI the signal is transmitted from the computer to the TV in FullHD format with a frequency of 60-65 Hz.

    But there are exceptions, and they are primarily related to the video device driver. Therefore, there is no need to try to get the TV to work correctly from the remote control. remote control, only this will help fine tuning video cards. The main thing is to always remember that you need to change the parameters not global, but just one port, otherwise, through negligence, you can destroy the signal to the PC monitor, which will be very difficult to restore.

    Working with drivers

    Making a TV work like a computer monitor via HDMI, although difficult, is quite possible. There are many ways to do this, which the reader will get to know. Owners of the Windows operating system versions 7,8 and 10 need to go to the control panel and select “Screen”.

    By going to the “Setting screen parameters” tab, the user will find that the operating system has already detected the connected TV, but is not yet transmitting the image to it. The Multiple Displays option allows you to connect your TV as an additional monitor to your computer. The list contains several options from which the user is asked to make a choice:

    1. Duplicate these screens. The contents of the computer desktop will be displayed on the TV screen, and all actions performed by the user will be visible on both displays.
    2. Expand these screens. The most interesting setting, which allows you to virtually increase the desktop area (both vertically and horizontally).
    3. Show on screen no. Manually assigning a port for video output is not popular among users.

    Driver configuration features

    It's easy to send a signal to a TV, but adjusting the picture quality and transferring sound from a computer to a TV is not so easy. First, you need to decide on the extension of the desktop - diagonally or vertically. Experts recommend focusing on the physical location of the TV in the room relative to the PC monitor. On the control panel, in the “Screen Resolution” menu, you need to use the mouse to place icon No. 2 relative to icon No. 1 so that it is convenient to move desktop objects between displays.

    The second step is to adjust the TV screen resolution. The main thing here is to select a parameter that is supported by the connected display, otherwise a failure will occur and the video output port will be disabled. By clicking the "Advanced Settings" button, the user can select the display refresh rate, however, IT experts do not recommend changing the frequency unless the video card and TV support the 4K (144 Hz) standard. After making all the settings, you need to save the changes and exit the control panel.

    Tricks with sound transmission

    All users know that an HDMI cable transmits not only high-quality images, but also sound, but there is no corresponding setting in the display resolution settings. With audio transmission, everything is simple - at the hardware level, the sound is sent to an additional screen along with the video. That is, the user just needs to move the video player window onto the TV display with the mouse. The sound will be muted in the computer speakers, but the sound will be activated in the TV speakers.

    It is worth noting that mobile device or a computer is capable at the hardware level of supporting several video devices connected via HDMI and transmitting to them different image and provide them with sound accompaniment. True, there are exceptions, and they depend on the video adapter and sound card. Low-performance devices sometimes malfunction; they simply do not have enough power to process digital video signals and high-quality audio.

    Alternative driver setup

    Not only using Windows You can configure the video to be transmitted to the TV screen. Owners are given the opportunity to ensure high-quality transmission using a video adapter driver (Nvidia or Radeon). The setup algorithm is still the same: we connect the TV to the computer via HDMI and set the HDMI signal source from the remote control.

    But then the proprietary software video card manufacturer. Going to the application control panel Nvidia GeForce Experience or AMD Catalyst Control Center, you need to find the “Display” tab. One of the sub-items of this menu is responsible for setting up multiple displays.

    Feedback from users

    Often, when connecting a TV to a computer or laptop, device owners encounter problems that they try to solve together in the media. Most of the negativity that is found in reviews is associated with low-quality HDMI cables that were purchased at foreign auctions or in stores at a low price. A greedy person pays twice - all users who decide to save on buying an HDMI cable need to know about this.

    After adjusting display settings and saving, did the image on the main monitor disappear? This is the second problem that users often have to face. The reason is quite simple - the parameters of the main monitor have undergone changes. There is only one recommendation here - when connecting a TV to a computer, you need to control your actions. Number 1 in the system is always the main monitor - its settings cannot be changed. You can do whatever you want with the remaining numbers (2,3,4).

    In conclusion

    Yes, in order to create convenience for yourself, the user needs a little time and investment. You simply cannot do without this. There are instructions that spell out all the steps, they need to be followed clearly:

    • buy an HDMI cable;
    • configure the video adapter driver;
    • enjoy watching.

    The algorithm is simple, but there is a lot of work to be done. In fact, there is nothing complicated, the main thing is to follow the recommendations of experts and carry out strictly specified actions. Only after receiving an image from a computer or laptop on the TV screen and making sure that there is sound transmission, can you enter additional options and make fine tuning.
