How To Connect A Computer To A TV Via HDMI

Instructions for connecting a laptop to a TV via HDMI

Not all modern TV models come with Smart functionality. Of course, you can “upgrade” the device by connecting a special console, but there is a cheaper and easier way. It is enough to know how to connect a laptop to a TV via HDMI.

Connecting a laptop and TV is the SIMplest task. SIMply plug one end of the wire into a jack on your laptop and the other into a port on the back or side of the TV. What will it give? Once connected, you can watch movies, TV shows and sports broadcasts on the big screen. In fact, TV will act as a second screen. Everything that you run on a laptop is automatically broadcast to the TV screen.

How To Connect A Computer To A TV Via HDMI

Setting up your TV

With the cord plugged into the TV, grab the remote control to open the main menu. You need to switch to HDMI, that is, change the signal source. Each TV set has a different setup menu.

Mostly the signal source is selected in the “External inputs” section or using the “Source” button on the remote control. Prioritize the HDMI connector on your TV with the same number to which the cable is connected. When you are done, the laptop desktop will appear on the screen.

What you need to connect a laptop to a TV via HDMI

Before proceeding to consider the question of how to connect a laptop to a TV via HDMI, we will make a list of the necessary devices. You only need three things:

  • HDMI cable;
  • TV set;
  • laptop.

Syncing your TV and laptop is a SIMple process. You only need to buy a cable that will allow you to duplicate the image on a large screen. It is very rarely included in the basic package. It is inexpensive. The program for connecting to a laptop TV is not required. Therefore, no special skills are required either. Just follow the instructions.


Connecting a laptop to a TV via HDMI is performed as follows:

  • Find the HDMI interface on your laptop. It is usually located on the left or right.
  • Find the connector on the TV through which we will connect the laptop. It is located on the back, sometimes on the side. Remember its number, it is usually written in small print next to the connector.
  • Connect laptop and TV with HDMI cable. It is the cord that acts as a connecting element.

When you have connected the cable, the connection is complete, proceed with the setup.

Laptop settings

When everything is connected, you can adjust the image quality. This is a mandatory measure if HDMI from a laptop to a TV displays a picture for the first time. Otherwise, the image may be fuzzy, blurry.

Follow the SIMple step-by-step instructions:

  • Right click on an empty space on the desktop.
  • From the drop-down context menu select the command “Screen resolution”.
  • By adjusting the screen resolution, you must select the optimal picture quality.

Change the resolution and see how the image quality has improved or deteriorated. There are also several options for connecting to a TV:

  • mirroring the laptop screen to TV;
  • expanding the working area;
  • TV as a second monitor. laptop screen and TV screen work independently. You can, for example, SIMultaneously play a movie on TV and surf the Internet or work behind a laptop screen. This type of connection creates a load on the card;
  • laptop screen is off, only TV is working.

This completes the setup. Now you can enjoy watching your favorite movies on the big screen. Setting up a connection on a netbook is carried out in a SIMilar way.

Possible problems

What to do if the resolution setting does not give the expected result. The easiest way is to press the “WinP” key combination. A window will open through which you can additionally adjust the picture quality.

Select Projector Only or 2 Screen Only. Wait for the Windows operating system service to automatically select the optimal resolution.

In some situations, the suggested recommendations do not help. After selecting source and adjusting the resolution, the image is still too distorted. Black bars may appear on the sides of the screen or the picture may be cut off. In this case, you need to configure the map.

As an example, let’s consider the optimization of the basic parameters of an NVIDIA card:

  • Click on an empty space on the desktop with the right mouse button. In the drop-down menu select the command “NVIDIA Control Panel”.
  • On the left there will be a list of special functions, click on the section “Change resolution”.
  • In the panel on the right, select disPlay, and in the bottom menu, click on the “Settings” button. We select the command “Create custom permission”.
  • A window appears with detailed picture settings for the large screen, which is the TV.
  • At the top, change the number of pixels horizontally and vertically. Run a “Test” from time to time to check the correctness of the entered parameters. Continue until you find the optimal screen resolution.

For laptops with a graphics processor from ATI, the setup instructions will be slightly different due to the different interfaces. However, the aLGorithm itself is approximately the same.

What is important to know about HDMI?

Recently, HDMI data transmission technology has become very popular. Largely due to the fact that with its help it is possible to broadcast an audio signal of a sufficiently high quality. This uses only one cable.

There are currently several HDMI standards:

  • 1.0 standard (speed up to 10.2 Gbps, support up to 8 audio channels);
  • standard 2.0 (data transfer at speeds up to 18 Gbps, as well as support for up to 32 audio channels).

Many companies manufacture HDMI cables. Branded options are often quite expensive. However, many modern TVs have such a cable included.

How to output sound to TV via HDMI?

  • All necessary drivers must be installed on the card. You can determine if the driver that provides audio output via HDMI is installed in the “Device Manager”. To open it, you must click “WinPause”, then select “Device Manager”. In the section dedicated to sound, gaming, and devices, a device that supports “High Definition Audio” must be indicated. high definition sound:
  • Playback devices (right-click on the speaker located near the clock or go to “Control Panel. Sound”) must have an HDMI digital audio device or SIMilar in name.
  • When the TV is connected to a computer device, the status will change to “Ready”. Right click on it and select “Set as default”.
  • On some TVs, not all HDMI inputs are capable of receiving sound! The port called “HDMI 1” probably knows how to do this. If the sound does not appear automatically, try to rummage in the TV settings to set the digital, not analog (used when connecting tulips) audio stream for the HDMI input you are using.

After that, the problem with the output of sound via HDMI to the TV should be resolved. You just have to restart the programs you are using or completely restart your computer.

What OS do you have installed?

HDMI setup

After Windows boots up, select the appropriate screen resolution. To do this, right-click on an empty space on your desktop and then select the appropriate “Screen Resolution”.

Here you can choose the appropriate resolution. A higher resolution provides a sharper picture, but everything on the screen will be smaller. The system defaults to the maximum resolution supported by the device. If everything suits you, don’t change anything. If you are not comfortable working with such a resolution: the font is too small and difficult to read, you can reduce the resolution, taking into account some nuances. Some monitors and TVs are designed to show a strictly defined number of pixels vertically and horizontally. If you set a non-standard resolution, your TV will have to scale it to display it on its matrix, which can lead to blurring of the picture and deterioration of the image quality.

If your TV supports Full HD resolution (1920 × 1080), it will play 1280 × 720 no less well, but all fonts and details will be larger. The real resolution of the HD Ready TV is 1366 × 768, it makes no sense to set the resolution to 1920 × 1080.

On the monitor tab, located in the “Advanced settings”, you can set the required refresh rate. You can set it to 60 Hz or more (if your TV supports it):

If the playback is not smooth enough or shakes, you can experiment with this parameter by changing its value. Set the color quality to “True Color (32-bit)”.

Whenever you change the resolution, color depth or frequency, a window appears in which you need to confirm the changes. If your device does not work with the new parameters, you will not be able to see this window and confirm your actions. Don’t worry, in fifteen seconds your computer device will be restored to its previous system settings.

How to connect a computer or laptop to a TV via HDMI?

Many people who have a large plasma or liquid crystal TV at some point think about connecting it to their computer or laptop. The opportunity to watch a movie on a large screen is of great interest to many users. First, let’s get acquainted with the possible ways of connecting these devices, then we will understand the settings of the card, and at the end we will consider how you can output sound via HDMI. For the SIMplest connection of the above devices, you only need to have an HDMI cable with the same connectors at the ends. Any, even the most inexpensive cable is suitable, but note that if you are going to use 3D mode, the version of the cable must be HDMI 1.4 or higher. Find the HDMI jack on your computer case and on the back of your TV. This is what this socket looks like on the back of the TV: And this is an image of the socket on the side wall: But such a socket should be looked for on the back of the computer system unit: This socket is located directly on the card, next to the connector for connecting a DVI or VGA monitor. If a discrete card is not installed in your system unit, the socket will be located on the motherboard, near the USB ports. With laptops, it is lighter, the HDMI socket in them always looks the same, it just can be located on different sides in different models: In portable computer devices (tablets, netbooks, cameras, etc.) install mini-HDMI connectors, which are three times smaller than a conventional connector, so they need a mini-HDMI cable.

Many modern users have an LCD TV hanging on the wall, which makes it difficult to connect a massive cable to its back surface.

For such cases, cables are provided with the plug at right angles. You can also, if you wish, purchase a special HDMI corner: With this corner, you can connect to the TV from the back or from the side. Some adapters even support the ability to adjust the angle and the bend in them is not straight, but in any direction. Before buying, decide in which direction the cable will come out after connecting it through the corner. Please note that different cable models are oriented in different directions.

You will not be able to connect without HDMI connectors (however, if you have a connector for a DVI monitor, you can use a DVI-HDMI adapter).

How to connect laptop to TV via hdmi

Sometimes you need to connect your laptop to your TV. For example, to display an image on a larger screen. Since the “native monitor” is not always enough for comfortable viewing of photos or movies. For this, in most cases, an HDMI cable is used. After all, there is a connector for it in almost any modern TV device. You just need to understand how to connect a laptop to a TV via hdmi.

Several ways to connect your smartphone to your TV

Smartphones that have appeared relatively recently are developing by leaps and bounds, offering users an ever wider range of opportunities: high-speed Internet access, all kinds of applications, social networks and exciting games have long become the norm for the owner of a “smart” phone. In search of expanding the capabilities of their gadgets, users are increasingly looking to learn how to connect a smartphone to a TV in order to use the latter as a solid-sized display. This will allow you to watch movies (stored in the memory of the gadget) on a full screen, take a completely new look at your favorite games and bring communication with friends on social networks or via Skype to a new level.

The purpose of this article is to acquaint you with the basic methods of connecting a smartphone to a TV. If you came to this page, you probably know why you need to create this type of connection. Therefore, it makes no sense to waste your time on a long introductory part, it is better to go straight to the description of specific methods and actions.


This method is not in vain made in the first place: HDMI has recently gained immense popularity, and connectors of this type can be found on most modern electronic devices (smartphones are no exception). HDMI is loved by users for its high quality and bit rate in digital format. Just one cable allows you to set up “sending” as. and audio signals to TV.

It is not difficult to guess that a prerequisite for connecting your smartphone to a TV via HDMI will be the presence of the same-named connectors in both devices (in smartphones you can find micro-HDMI or mini-HDMI). You can verify their presence by reading the instructions, or visually (on the TV they are located on the back panel, in the smartphone, most often next to the USB connector).

The connection is created as follows: turn off the tablet and TV, then, after connecting both devices with an HDMI cable, turn them on. In most cases, after switching on, the connection will be automatically set up, the result of which will be the activation of the “mirrorring” function, in which the image from the smartphone display will begin to broadcast to the TV.

If automatic configuration did not happen, you can do it manually: for this, go to the menu of both devices. In the TV set, select the signal source “HDMI” (if there are several HDMI connectors on the back of the TV, indicate the number of the one used), and on the tablet, activate the signal transmission function via HDMI. That’s all. This completes the connection process. Moving on to the next method.


This method of connecting these devices is also possible. Yes, it will not allow you to duplicate the image from the tablet display to the TV, but you will be able to use the gadget as a USB drive acting as a signal source. In this case, data management is carried out using a TV interface, and a modern TV is able to “read” not only most audio formats, but also common formats of text documents and presentations. Thanks to this, you can turn your TV into an advanced whiteboard for presentations and slideshows from your favorite photos.

How to connect? It’s very SIMple: take a “micro USB” cable (or “mini USB”. depending on what type of output your smartphone has), plug one end into a special connector on the phone, and the other into one of the USB ports on the back of the TV. Do not forget to turn off both devices in advance so that when you turn them on, you get a working connection that does not require any edits.

This concludes the “wired” connection methods, we pass on to the description of the wireless, through which you can establish the operation of devices.

Wireless connection methods

Advances in wireless technology have provided a wide variety of ways to connect in this way. Each TV manufacturer is trying to release a unique application that provides a connection with a smartphone via Wi-Fi.

So, LG TVs offer the ability to connect via Smart Share, a software product that allows you to connect a compatible phone of the same brand to a TV via Wi-Fi (due to the fact that LG Smart TVs in most cases are equipped with a built-in Wi-Fi module, no problem connection should not occur). It is enough to have a configured home Wi-Fi network, connect both devices (smartphone and TV) to it and activate the Smart Share function on them.

Another giant of the entertainment industry, Samsung, offers its users the AllShare function (as a SIMple and reliable way to connect a smartphone to a TV). The essence of the connection is not much different from LG models (with Smart Share): set up a home network, connect both devices to it and activate the function responsible for the wireless connection.

We examined the “unique” ways to connect a smartphone to a TV, inherent in any one technology manufacturer. It remains to say a few words about universal connection methods that also use Wi-Fi wireless technology.

Wi-Fi Direct

This technology makes it possible to do without using a router with a configured home network, that is, you can connect the tablet to the TV “directly”. The main thing is that your phone and TV support Wi-Fi Direct technology. The main aLGorithm that allows you to connect a TV to a tablet in this way:

  • Launch Wi-Fi Direct on a smartphone. To do this, go to the device settings menu, select the “Wireless networks and connections” tab, then look for Wi-Fi Direct, opposite which you need to click on “activate” (or “OK”). You should see a message about the successful launch of the function.
  • We put the smartphone aside and go to the TV. Here we also go to the menu and, through it, we get to the “Network” tab (you can often find a special button on the remote control that facilitates access to this menu item). Among the connection methods, we look for “Wi-Fi Direct” and activate it. After activating the function, it will be possible to select a device for connection (in our case, this is a smartphone that we configured a couple of minutes ago). Select your phone (be guided by the “device name on the network”; it can be set in the gadget settings) and send a connection request. In just a few seconds, the smartphone will “catch” the request and offer you to complete the connection setup by pressing the “yes” button.
  • That’s all. You can start using Wi-Fi Direct technology at your pleasure.

As you can see, there are a lot of ways to connect a TV to a smartphone. You need to clearly understand the goals that you are pursuing and know the technology that you can turn to in your case (which connection method is supported by both the TV and the smartphone). It only remains to take a couple of steps to connect the devices, and you can start using them “in pairs”.

We connect the computer to the TV via HDMI

The HDMI interface allows you to transfer audio and signal from one device to another. In most cases, to connect devices, it is enough to connect them using an HDMI cable. But no one is immune to complications. Fortunately, most of them can be quickly and easily solved by yourself.

Introductory information

First, make sure that the connectors on your computer and TV are the same version and type. The type can be determined by the size. if it is approximately the same for the device and the cable, then there should be no problems when connecting. The version is more difficult to determine, since it is written in the technical documentation for the TV / computer, or somewhere near the connector itself. Usually, many versions after 2006 are quite compatible with each other and are capable of transmitting sound along with.

If everything is in order, then firmly plug the cables into the connectors. For the best effect, they can be fixed with special screws, which are provided in the construction of some cable models.

List of problems that may arise when connecting:

  • An image is not displayed on the TV, while it is on the computer / laptop monitor;
  • No sound is transmitted to the TV;
  • Distorted picture on TV or laptop / computer screen.

Image adjustment

Unfortunately, the image and audio on the TV does not always appear immediately after you plug in the cable, since for this you need to make the appropriate settings. Here’s what you might need to do to make the image appear:

  • Set up the TV source. You will need to do this if you have multiple HDMI ports on your TV. You may also need to select the transmission option on the TV, that is, from a standard signal reception, for example, from a satellite dish to HDMI.

Configure to work with multiple screens in your PC operating system.

  • Check if the drivers on the card are out of date. If outdated, then update them.
  • Do not exclude the possibility of viruses penetrating your computer.
  • Sound setting

    A common problem for many HDMI users. This standard supports the transmission of audio and content at the same time, but not always the sound comes immediately after connection. Too old cables or connectors do not support ARC technology. Also, sound problems can occur if using cables from 2010 and earlier.

    Fortunately, in most cases, it is enough to make some settings of the operating system, update drivers.

    To properly connect the computer and the TV, you just need to know how to plug in the HDMI cable. There shouldn’t be any difficulties in connecting. The only difficulty is that for normal operation, you may have to make additional settings in the TV and / or computer operating system.

    Setting the resolution and frequency

    Sometimes, after following the above recommendations, the picture is still not broadcast. In this case, the reason may be that the TV and the system unit are not compatible in their parameters. For example, for an old SD or HD TV, the FHD resolution on the PC card is too high. In this case, it is worth entering the screen settings according to the above aLGorithms and, having selected the second display (TV), lower the resolution for it.

    The second reason that can affect the image is frequency. By default, the PC card is set to 60Hz. For TV, try decreasing the value gradually.

    Some Samsung TVs had an issue where a window appeared with the text “HDMI mode not supported”. There were many recommendations on the forums to combat this, but it turned out that this was a problem with the factory firmware, and in order to fix the defect, you need to contact the manufacturer’s service center, where the new software is installed. Modern Samsung TVs don’t have such nuances.

    Cable check

    Not a single product, even the most reliable brand, is immune from factory defects, especially when assembled by hand. When buying, the image quality and sound are checked, but they never check specific connectors and connection jacks on the TV. at best they make sure they are available, and even then not all buyers. It often happens that the cable itself does not work, although it has not been used for so long. It is necessary to connect the same cable, but to another device, if it functions normally, then the reason that the computer does not see the TV lies in the latter. It is necessary to diagnose the TV in order to recognize SIMilar signals.

    We carry out diagnostics

    What should be done if the TV cannot see the laptop via HDMI? cards of all modern products support such a connection: HDMI is installed on the TV on almost every model. If the laptop was connected in accordance with all the rules, but still there is no image, then we connect the laptop to the TV, while sequentially checking all possible problems.

    Checking the signal source

    On the remote control (RC), press the button to select the external input option. The specific model of the product depends on which button on the remote control of the TV must be pressed: “source”, “input” or “HDMI” (LG, Sony or Samsung). After pressing, a menu appears on the screen with a detailed list of active inputs. We select and confirm by pressing OK or Enter, it is the desired input to which the cable from the laptop was previously connected.

    Why TV can’t see laptop via HDMI

    How to update software on the card

    If the difficulties with connecting after the recommendations above have not gone away, then updating the software for a PC related to image display can help. The driver might be out of date, damaged, or SIMply missing. In such a situation, you should open Device Manager and look at the “Adapters” tab. To do this, on the icon “my computer” select “control” in the menu, which opens by clicking on the right mouse button.

    If a red or yellow icon is lit next to the adapter, then there is a problem with this node. To update, you can immediately open its properties and select automatic driver update, but it is more efficient to download it from the manufacturer’s website.

    Image output settings in Windows

    If the connection cord and interfaces work, but the system unit still does not display the picture on the TV screen, then the problem lies in the operating system settings. How to properly configure the system unit for different OS versions is described below.

    • On the desktop, you need to open the task menu and find the item “screen resolution”.
    • We select the item “connect to the projector” and click duplicate so that the image remains on each monitor. If you need to completely transfer the picture to TV, then click on “projector only”.
    • After entering the control panel, you should select the submenu “design and personalization”.
    • In the “screen” section, we find “multiple displays” and select “duplicate” or “expand the table only on the second display”.
    • In the screen parameters, select “display” and scroll to “multiple displays”.
    • If all connections are made correctly, then the second screen will be immediately displayed, all that remains is to indicate exactly how to use it. duplicating or as the main one.

    Connection port malfunction

    Any connector can have mechanical damage or burn out during a power surge, which are not uncommon in our electrical networks. Experienced masters advise to connect the HDMI cable when devices are disconnected from the network, even the antenna cable is recommended to be disconnected for this time.

    There is also such a very rare reason why the TV does not see HDMI: it SIMply does not have additional power on the card, and without this the connection will not work.

    computer settings

    The misconfiguration of a multi-screen computer / laptop is also the reason why HDMI connection is ineffective. If no external displays other than a TV are connected to the computer, then this method may not be considered, since problems arise if another monitor or other device is connected to the PC or laptop using HDMI (sometimes other connectors, for example, VGA or DVI).

    A step-by-step guide to setting up multiple screens for Windows 7/8 / 8.1 / 10 devices looks like this:

      Right-click an empty area on the desktop. In the menu that appears, you need to select “Screen Resolution” or “Screen Settings”.

    Under the picture with the screen on which the number 1 is written, you need to click on the item “Find” or “Find” for the system to detect and connect the TV.

  • Then the “Display Manager” opens, where the settings for several screens are made. Make sure the TV is detected and connected correctly. If all is well, then in the window where one rectangle of the screen with the number 1 was previously displayed, a second SIMilar rectangle should appear, but only with the number 2. If this did not happen, check the connection.
  • In the “Display Manager” you need to select options for displaying information on the second display. There are 3 offered in total. “Duplicate”, that is, the same picture is displayed on both screens; “Expand screens”. both will complement each other, creating a single workspace; Show Desktop 1: 2. the image is displayed only on one of the displays.
  • For correct operation, it is advisable to select either “Duplicate” or “Display Desktop 1: 2”. In the latter case, you also need to specify the main screen (TV).
  • It is worth remembering that HDMI is capable of providing a single-stream connection, that is, correct operation with only one screen, therefore it is recommended to disable an unnecessary device (in this example, a monitor) or select the display mode “Display desktop 1: 2”. First, you can see how the image will be broadcast to 2 devices at the same time. If you are satisfied with the quality of the broadcast, then you do not need to change anything.

    update drivers for the card

    Initially, it is recommended to know the characteristics of your card, since some graphics adapters are not capable of supporting output to two displays at once. You can find out this aspect by looking at the documentation for the card / computer / laptop or using third-party software.

    First, update the drivers for your adapter. You can do it like this:

      Go to “Control Panel”, put “Display” to “Small icons” and find “Device Manager”.

    In it, find the “adapters” tab and open it. Select one of the installed adapters if there are several;

  • Right-click on it and click “Update Drivers”. The system itself will find and install the necessary drivers in the background;
  • SIMilarly to point 3, do with other adapters, if several are installed.
  • Also, the drivers can be downloaded and installed from the Internet, necessarily from the manufacturer’s official website. It is enough to indicate the adapter model there in the appropriate section, download the required software file and install it, following the instructions.

    TV does not see computer via HDMI

    HDMI is a popular connector for interfacing various equipment with each other (for example, a computer and a TV). But when connecting, all sorts of difficulties can arise. technical and / or software. Some of them can be solved independently, to eliminate others it may be necessary to hand over the equipment for repair or replace a faulty cable.

    correct TV settings

    Some TV models are unable to independently determine the signal source, especially if any other device was connected to the TV via HDMI before. In this case, you will have to re-drive all the settings. The instructions for this case may vary slightly from the TV model, but its standard version looks something like this:

    • Connect the laptop to the TV using an HDMI cable, make sure that you connected everything correctly and the contacts do not come off. For persuasiveness, you can additionally tighten special screws, if they are provided for by the design;
    • On the TV remote control find any button with one of these names. “Source”, “Input”, “HDMI”. With their help, you will enter the connection source selection menu;

    Select the desired HDMI port from the menu (many TVs have two). The required port can be viewed by the number of the connector where you plugged the cable (the number is written above or below the connector). To navigate through the menu items, use either the channel switching buttons or the numbers 8 and 2 (depending on the TV model);

    For some TVs, the instructions may look slightly different. In the second paragraph, instead of the proposed options, enter the TV menu (a button with a corresponding inscription or logo) and select the HDMI connection option. If the TV has several connectors of this type, then do the rest in accordance with paragraphs 3 and 4.

    If this method did not help, use the instructions for the TV (it should say how to connect via HDMI cable to this particular device) or pay attention to other ways to solve the problem.

    General Tips

    If you have a cable with any intermediate adapters, for example, you can use it to connect to a DVI connector. Instead, it is better to try using a regular HDMI cable operating in HDMI-HDMI mode, as the TV / monitor may not perceive a cable that implies the ability to connect to multiple ports at the same time. If the replacement does not help, then you will have to look for and eliminate another cause.

    Check the HDMI ports on your computer / laptop and TV. Pay attention to these defects:

    • Broken and / or rusted, oxidized contacts. If any are found, then the port will have to be replaced completely, because contacts are its most important component;
    • Dust or other debris inside. Dust and debris can distort the incoming signal, which will cause inconvenience during reproduction and audio content (quiet sound or no sound, distorted or braking image);
    • See how well the port is set up. If it begins to loosen at the slightest physical impact, then it will have to be fixed either independently or with the help of employees of specialized services.

    Perform the same test on your HDMI cable, pay attention to the following points:

      Broken and / or oxidized contacts. If such defects are found, the cables will have to be replaced;

  • Physical damage to the wire. If the insulation is broken in some places, there are deep cuts, fractures or wires are partially exposed, then such a cable, if it will reproduce something, then with various defects. It can also be dangerous to health and life, since there is a risk of getting an electric shock, so it needs to be replaced;
  • Sometimes there may be debris and dust inside the cable. Clean it gently.
  • Please understand that not all cables match all HDMI connectors. The latter are divided into several main types, each of which has its own wire.

    we clean the computer from viruses

    Least of all, problems with the output of a signal from a computer to a TV via HDMI arise due to viruses, but if none of the above helped you and at the same time all cables and ports are working, then the probability of a virus penetration should not be ruled out.

    To protect yourself, it is recommended to download, install any free or paid antivirus package and regularly use it to scan your PC for dangerous programs. Let’s consider how to start a PC scan for viruses using Kaspersky Anti-Virus (it is paid, but there is a demo period for 30 days):

      Run the antivirus program and in the main window select the scan icon with the corresponding signature.

  • Select the type of check in the left menu. It is recommended to select “Full scan” and click on the “Start scan” button.
  • The “full scan” may take several hours, and upon completion, all detected dangerous files will be displayed. Some will be removed by the antivirus program itself, others will offer you to delete if it is not 100% sure that this file is dangerous. To delete, click the “Delete” button opposite the file name.
  • Problems with connecting a computer with HDMI to a TV do not occur often, and if they do appear, they can always be solved. Provided that your ports and / or cables are broken, they will have to be replaced, otherwise nothing will be output.
