How to find out if hdmi is working on your computer. Computer hardware capabilities

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 the correct equipment settings. 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 it is to view multimedia and the better the 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 the technical capabilities of a 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 the motherboard of the computer and on one of the ends of the mobile laptop.

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

Larger LCD displays have a slightly different problem. We are talking about the resolution of the reproduced image and the frame rate. Before connecting a computer and a TV via HDMI, the user needs to familiarize themselves with the technical characteristics of both devices, compare their video signal transmission capabilities and find a parameter that will be supported by both the plasma and the 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 equipment of different generations by 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, foreign auctions offer ready-made solutions that can solve all users’ problems 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, since with obsolete devices the problem can always be solved. The fact is that old equipment is focused on transmitting an analog signal. Although this technology lags behind in image quality, it has an order of magnitude fewer problems with the compatibility of different standards. 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, you can forget about the convenience of sharing a computer and TV.

The right approach to buying a cable

Problems may also arise for the user when choosing the wrong HDMI cable. 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 a middle ground in terms of the “cost - cable length” ratio.

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 electrical charge on the video ports when the equipment is plugged into the mains. 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 avoids all users who have grounding in their home.

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 - in 99% of cases 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 the liquid crystal display to press the “Source” button on the device’s remote control and select the desired signal source. All ports on the TV panel are registered and numbered, so all that remains is to combine the software part with the hardware part. 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 completes 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 all HDMI ports are 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 the new display. The more modern the equipment, the more efficient the automatic tuning is - 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 make the TV work correctly from the remote control; only fine-tuning the video card will help here. 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:

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.
Expand these screens. The most interesting setting that allows you to virtually increase the desktop area (both vertically and horizontally).
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 a mobile device or computer is capable of supporting several video devices connected via HDMI at the hardware level, transmitting different images to them and providing them with sound. 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 Windows tools can configure video transmission 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 of the video card manufacturer is used. Going to the control panel of the Nvidia Geforce Experience or AMD Catalyst Control Center application, 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, you can go into additional parameters and make fine adjustments.

How to connect a computer to a TV

Good afternoon, dear readers of the portal Your World PC. In today's article we will show you how to connect your TV to your computer via HDMI. To set up the connection we will need: a computer with a video card that has an hdmi output, a TV and the hdmi cable itself. If you do not have such a cable, you can use another one, vga or dvi. But be sure to make sure that your TV has the appropriate inputs. If your TV has hdmi, then we recommend using it, because if you connect the TV to your computer via vga or dvi, you will need another cable to connect the audio. But when connected using hdmi, everything will be output to the TV via one cable, both video and sound.

Connecting a cable from your TV to your computer using HDMI

In our article we will connect the TV to the computer using a 10 meter HDMI cable. If you use a different type of cable, the connection and all settings will be exactly the same as ours.

So, first we connect the cable to the computer. On the back side of the system unit, we find the HDMI output on our video card and connect one of the ends of our cord into it.

After this, we connect the second end to the TV (you can connect both with the equipment turned on and off, but we would still recommend that you turn it off).

Connection with other cables - VGA and S-Video

In fact, the process itself does not change, only the cord and the sockets into which you will connect it change. But to make it clearer and more visual for you, we will show you which cords need to be inserted where.

So the VGA cable is analog video. This cable has the following appearance.

It connects to the computer into this socket.

And on TV this is it.

Important tip! Please note that VGA cables have a very big disadvantage. When using cords longer than 5 meters, the picture quality decreases very sharply. For example, we had experience when we connected a regular monitor using a 10-meter VGA cable. The image quality dropped so much that it was extremely difficult to read the text, and the video was very blurry! So, if your computer is located more than 5 meters from the TV, then use only HDMI.

The S-Video cable is an outdated format (mostly used only on video cards of older computers). This is what he looks like.

On the computer it is connected to where the arrow indicates in the photo.

And on the TV, this is the connector.

Settings to make on your computer

Step 1 - Setting Up Screens

Now that our cable is already connected, we start the computer (we don’t turn on the TV yet). When the computer boots, turn on the screen settings. To do this, right-click on an empty space on the desktop and select the “Screen Resolution” property. Here you can configure image output settings on your computer and TV.

For example, you can duplicate screens (that is, what you see on the computer screen will be the same on the TV).

You can simply expand the screen (this means that the TV will be an extension of the computer monitor screen. You can turn on the movie and drag it onto the TV with the mouse, and go about your business on the computer).

Just select the mode that suits you and click the “apply” button.

Step 2 - Adjust TV Resolution

The next step is setting the TV screen resolution. Why is this necessary? If you do not adjust the resolution, the picture on your TV will not be full screen, but something like this.

Therefore, in the screen settings, select our TV.

And we set the resolution for it, we recommend setting the resolution to 1024 by 768 (this is a standard resolution that is suitable for almost all TVs. If even with 1024 by 768 the picture does not fit the entire screen, try other resolution options and choose yours). On our TV, with this resolution, the picture is displayed on the entire screen.

Step 3 - Sound Settings

So, we have already configured the picture output to the TV, now we need to configure the sound output. To do this, go to “control panel - hardware and sound - manage sound devices”.

In the window that opens you will see a device called HDMI Output. These are your TV speakers. In order to enable audio streaming to them, you need to set them as your default device. To do this, right-click on the device icon and select “use as default” and the apply button. After this, the sound will be output on the TV.

Settings to make on your TV

Now that all the settings have been made, you can turn on the TV. To connect it to a computer, you need to specify the signal source in its settings. This is done simply. Go to the menu and look for similar settings there. In our case, on an LG TV, you can access these parameters by pressing the “input” button on the remote control.

A menu will open in which you need to select HDMI and press the “ok” button on the remote control. After this you will see a picture.

That's it, now you already know how to connect a TV to a computer and you can comfortably not only watch movies and listen to music, but also play video games.

In the era of high digital technology, we can get the best from the TV and computer through their connected connection. Creating such a special connection between technical devices is possible with the assistance of DVI, HDMI or VGA connectors. But, often and for various reasons, these devices do not want to make contact with each other. You can always eliminate existing problems if you know what lies at the root of their occurrence. An approximate description of common problems will help you navigate a difficult situation and open up new ways to eliminate them.

What is HDMI?

HDMI is a multimedia interface that transmits high-definition video and digital audio signals. This type of cable is widely used for connecting TVs, game consoles, stand-alone video players, as well as audio receivers to mobile devices and computer equipment. If you want to play a video or show photos on a big screen, then you can’t do without such a device.

Manufacturers of modern multimedia equipment now add HDMI connectors to the standard equipment of devices by default. There are five main types of such ports, which are marked with Latin letters from A to D and differ in size. In addition, each type of HDMI cable differs from the other in functionality and scope of application.

It is also worth noting that recently the possibilities and advantages of a wireless connection when connected via HDMI adapters have been widely discussed. Outwardly, they resemble USB-Bluetooth and differ only in the connectors.

Connecting the TV

Watching movies, amateur videos and photos is much more convenient on a big screen, especially since almost all modern video cards allow you to connect to a TV. The picture quality and sound playback on a computer is significantly different from what you will see and hear if you connect a blue screen to it.

There are the following basic ways to connect a TV to a monitor:

The connection can be realized without using various types of wires. A connection via WIFI allows you to quickly establish contact between the monitor and the screen, and in addition, frees your home from a web of cables.

Turn on devices

The TV can always be transformed into a powerful multimedia platform if you turn on all devices in the right sequence.

The connection algorithm is as follows:

The sequence of operations must not be changed under any circumstances. After connecting the devices, they need to be configured.

How to set up your display

The Windows 8 and 7 operating systems themselves detect the device and configure the connection if an HDMI cable is used. When using other connection methods, you need to know how to configure the image output to the display yourself.

The algorithm for displaying images on the display in Windows 7 and 8 systems is as follows:

Setting up the display in the Windows XP operating system is always done manually. You will have to press the buttons a little and switch the TV to AV mode.

Setting up the video card

After the connection is made correctly, a picture from the computer should appear on the TV screen. If the image does not appear, you need to adjust the inputs and outputs and adjust the resolution.

The video card is responsible for all visual effects and display of multimedia files on the computer. Each model has its own characteristics that should be taken into account when setting up.

But the general algorithm of actions will always remain unchanged:

Successful completion of the connection of two devices will be indicated by a system message about the use of an additional screen.

Outputting sound to TV

Playback of multimedia files will be complete only after setting up the sound card. If you don't do this, then you'll just end up in the silent film era.

Sound output to the TV is carried out according to the following plan:

If after making all the settings nothing plays, you need to pay attention to whether the video card even supports your sound output method.

What to do if the computer does not see the TV via HDMI?

Almost every modern TV model is equipped with an HDMI connector. Most video cards support multimedia output in this way. But if the computer does not see the HDMI TV, you need to find out what is preventing the two devices from connecting.

Diagnosing problems includes the following steps:

step one: check the HDMI cable for serviceability and correct connection;
step two: check the system settings and working with a computer via an HDMI cable in the TV menu;
step three: reinstall the video card drivers.

Some types of TVs simply do not support an HDMI connection and you should not forget about this. We are talking (mostly) about outdated models that are not equipped with a special connector. In such cases, you can try other connection methods. For example, via DVI or VGA.

Video: computer does not see TV

Possible reasons

The disease can be cured if you know the causes of its occurrence. Problems connecting your TV to your computer can be resolved if you know what caused them to appear.

The main reasons why the computer does not see the TV:

the connection cable is damaged, incorrectly connected or defective;
the computer does not detect the TV;
the TV does not support the selected connection method;
video card drivers or lack thereof;
damage to interface ports;
the computer has a removable video card installed;
burning of internal parts of a TV or computer.

There can be many reasons for problems in the coordinated operation of two devices. If you are not a specialist, then you can confidently diagnose only external problems associated with the cable.

Solving the problem

Knowing the causes of the main violations in the symbiosis of a computer and TV, any problem can be eliminated.

Troubleshooting algorithm:

You shouldn’t try to fix problems on your own that only a professional can handle. But basic mechanical restorations are within the competence of any PC user. Do you really need to contact a technician to correct the position of the cable?

No signal from computer to TV

The absence of a signal most often indicates that this TV model cannot be connected via HDMI. It is possible that the connection type is incorrectly marked in the options. In this case, you should try other connection methods.

Photo: connecting a TV to a video card

The reason for the lack of signal on the TV may be viruses, outdated drivers for the video card, or cable failure. Be sure to check the video card settings and select the correct type of information display. Finally, look into the BIOS and check the activity of the connection elements.

Checking the signal through different connections

Through trial and error you can achieve the truth. If after all your efforts you are unable to resolve the connection problems, you can check the signal using different connection methods.

The due diligence process is as follows:

If the work done does not make any changes to the existing state of affairs, then, most likely, the reason for the lack of signal is some kind of internal breakdown or flaw in the cables and I/O ports.

The development of digital and multimedia technologies has given us the opportunity to enjoy viewing photographs, amateur and professional videos on a large screen TV. It is for this purpose that televisions are connected to phones and computers. The connection between two pieces of equipment, if done correctly, is established in the shortest possible time.

But it happens that the image or sound is not reproduced on the TV screen. There can be many reasons for this. It is important to install them so that the problem can be eradicated in the future. Only a specialist can conduct a detailed diagnosis of problems and fix them. You shouldn’t undertake serious restoration work yourself. But this rule does not apply to the elimination of minor and primitive defects.

I have long wanted to write a detailed review article on how to connect a computer to a TV with an HDMI cable. But writing about something I don’t know and haven’t tried, I consider it a deception. I decided to wait for an opportunity, and it soon presented itself.

Mom loves to watch all sorts of popular science films on YouTube video hosting. But in this case, I have to download them, then transfer them to a flash drive, and connect it to the TV. This process is time-consuming, not to mention the aggressive wear and tear on the computer’s hard drive.

And then I decided that it was better to save the hard drive, buy an HDMI cable and connect one of my TVs, which does not have the Smart TV software shell and a built-in Wi-Fi module, to the computer. Everything turned out to be much simpler than described on many computer websites.

Surely many of you have accumulated a lot of films downloaded from the Internet, which are much more convenient to watch on a big TV screen. And if the computer is also connected to the Internet, then you can watch any TV shows online, feature films and documentaries, and colorful slide shows.

I will describe how to connect a computer to a TV with an HDMI cable in order. Perhaps some of you will find this useful.

Connecting a TV via an HDMI cable is the easiest to set up and does not require a separate cable for audio. Both video and audio are transmitted over one cable, which is very profitable and convenient.

I will show and tell using the example of TV SAMSUNG UE32F4000 aw with a diagonal of 50 inches, not entirely new, but not old either.

We will need:

hdmi cable
TV with HDMI connector
video card with HDMI and DVI connectors

I had to buy 10 meters of HDMI cable, and it cost me one and a half thousand rubles. But compared to buying a new hard drive, this is nothing.

We lay an HDMI cable from the computer to the TV and connect it. I have two HDMI connectors on my TV.

The instructions for the TV say that you should connect the set-top box, VD player and PC to the connector HDMI 2, which in my case is at the top.

Connect the cable to the computer and TV only when the devices are turned off, otherwise it will fail.

We connect the second end of the cable to the HDMI connector of the video card.

Fig.4 HDMI connector on a discrete video card

Here's a small digression

Since I constantly work on a computer, and it is not very powerful, connecting a TV to it is not advisable. Otherwise, I will have to stop working and watch the same thing on the monitor as on the TV.

If my computer were more powerful, I could configure it with two different monitors, one of which would be a TV and show movies, and on the second I could do my own thing. For this it is better to have two video cards.

But since I have another computer, I made it a stand-alone set-top box for the TV. Therefore, the description below will concern a separate processor that can work without a monitor.

To set up the TV connection, we need any working monitor. Once set up, you can turn it off and put it away if you only use this computer for your TV.

Connect the cable from the monitor to the video card connector DVI. When connected to the connector VGA the monitor will not work.

Fig.5 Built-in video card connectors on the back of the computer

If the cable from the monitor has a connector VGA, then you will need an adapter VGA-DVI. They usually come with the monitor.

DVI and VGA connector (blue)

Now you can turn on your computer and TV.

Press the button on the TV remote control Source(View and select available video sources)

In the TV menu that opens, use the navigation buttons to select the source HDMI 2DVI(since the HDMI cable is connected to this connector), and press the remote control button « Enter"

A message will appear saying that the source was not found or something like that. This is normal and there is no need to panic.

Now let's go to the computer settings.

On the computer (I have Windows 7 installed), right-click on the desktop and select “ Screen resolution».

In the window that opens " Screen Settings"Press the button " Define" If the computer does not detect your TV, then check the connection source (the button on the TV remote Source). I chose the wrong connector at first HDMI.

As soon as in the field " Screen"The name of the TV will appear, then you can configure further.

Set your TV to the correct screen resolution. Usually the computer itself offers the correct solution, so don’t try too hard.

In settings " Multiple screens» install « Duplicate these screens" The TV should display the same picture as the computer.

Now you need to configure the sound.

Right-click on the sound settings icon in the system tray and select “ Playback devices».

In the window of available audio playback devices that appears, select the TV and click the button below Default", and then the button " Apply».

I have both a SAMSUNG monitor and a TV, so the program writes SAMSUNG-1.

All. Now you can enjoy watching your favorite series on TV. If you want to watch television programs, press the Source button on the remote control and select TV as the source.

By the way, if you also have two computers, and they are , then the computer through which films will be shown on the TV screen can be controlled using special programs through your work computer. In this case, you will not need to connect a monitor to the first computer.

If you are interested in this topic, write about it in the comments, and I will write an article and make a video on it.

I don’t connect a monitor, but start the system unit and make all the settings directly on the TV using a wireless mouse and keyboard.

The HDMI interface allows you to transfer audio and video signals 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 from difficulties. Fortunately, most of them can be quickly and easily solved on your own.

First, make sure that the connectors on your computer and TV are the same version and type. The type can be determined by its 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. Typically, many versions after 2006 are quite compatible with each other and are capable of transmitting sound along with video.

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

List of problems that may arise when connecting:

There is no image displayed on the TV, although there is one on the computer/laptop monitor;
No sound is transmitted to the TV;
The image on the TV or laptop/computer screen is distorted.

Step 1: Image Adjustment

Unfortunately, the image and audio on the TV do not always appear immediately after you plug in the cable, since this requires making the appropriate settings. Here's what you may need to do to get the image to appear:

Step 2: Sound Settings

A common problem for many HDMI users. This standard supports the transmission of audio and video content simultaneously, but the sound does not always come immediately after connection. Cables or connectors that are too old do not support ARC technology. Also, sound problems may occur if you use cables manufactured in 2010 or earlier.

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

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