In the case when Wi-Fi Direct is not configured, Miracast is not supported, there is no flash drive with a large volume, and you really want to watch a movie in good quality, we remember the HDMI connector - a great way to duplicate an image to another device without losing quality. Therefore, the question arises: how to connect a TV to a computer via HDMI in Windows 10 and what is required for this? The answer is below.
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 leave only negative emotions.
Connection instruction
So, to transfer an image to TV, we need to connect two devices using a cable:
Most likely, you will not see the projection of the laptop screen on the TV.
To do this, TV and PC need to configure:
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 to the TV screen, while the computer display itself will remain off. Selecting a different connection will cause two monitors to work 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 the TV screen, you need to:
Advice! If you do not have cable TV, and IPTV hits your wallet hard, you can watch TV through your computer: turn on online broadcast or sopcast on your PC and broadcast the image on TV.
How to connect a TV via HDMI?
Ever since high-definition video and audio transmission technology has appeared, it has entered our lives everywhere. Today, watching a high-definition movie on a TV via an HDMI cable connected to a computer or other digital media will surprise no one. However, this technology is still not used by everyone. There are people who do not know how to use it and what you can connect a TV to via an HDMI cable.
Therefore, below we will consider in detail how to connect a TV via HDMI to other digital devices, but first we will understand the types of HDMI cables.
How to choose an HDMI cable to connect
Currently, HDMI cables can be conditionally divided into expensive and cheap. Although, in fact, the production of an expensive or cheap cable does not differ qualitatively in almost anything. Therefore, to connect an HDMI cable to a TV, you should not choose on this basis.
Consider five types of HDMI cables:
- Standard HDMI is absolutely universal for all kinds of devices and is always tested for HD-quality data transmission.
- Standard HDMI Ethernet, in addition to transmitting high-quality video and audio content, also provides two-way data transmission over the Internet. This function is only effective if both connected devices support this cable feature.
- Automotive HDMIs are mainly used to transfer data between the car's on-board computer and any other digital media. Such a cable is tested by the manufacturer in very harsh conditions, which makes it resistant to vibration, heat, cold and other unpleasant things when operating a car.
- High HDMI speed has been designed for 3d, 4k and Deep Color transmission quality. Since the amount of data in this format is too large, a cable was needed that could transfer it as quickly as possible.
- High Speed HDMI with Ethernet is the fastest cable ever designed to deliver the highest quality video and audio. Such a cable is very expensive and allows you to transfer data over the Internet in both directions at high speed.

How to connect HDMI cable from TV to computer
Connecting a computer to a TV via an HDMI cable is not difficult in our time. It is enough to connect both devices with a cable via HDMI connectors and enjoy movies and games on the big screen in HD quality.
However, if your computer or TV does not have an HDMI cable input, you can purchase a hybrid cable that has an HDMI plug on one end and a DVI plug on the other.
Also, if your TV has an input for "tulips", then you must also find a hybrid cable for connection.
All modern widescreen TVs do not require additional drivers to see the picture on the big screen. However, you will need to set up a connection on your computer. To do this, you must have the latest drivers for the video card, with which you can switch the image from the monitor to the TV.
How to connect consoles to your TV with an HDMI cable
Many people play consoles on a big screen TV because it's convenient. You can use different cables to connect your set-top box to your TV, but an HDMI cable will provide the best quality.
To connect the set-top box, you need a TV that supports 1080p quality. The cable is simply plugged into the appropriate inputs on the set-top box and TV. Usually after that the TV detects the prefix automatically. In extreme cases, you can look at the setting on the website of the manufacturer of the TV or set-top box.
You can read more about connecting a PS3 set-top box in our article.
Connecting other devices with an HDMI cable to the TV
A huge number of devices and devices can be connected to the TV via an HDMI cable. All you need is a proper HDMI input on your device or a hybrid cable.
Using this method, you can connect to a TV:
- Mobile phone with the desired input or using a hybrid cable.
- Modem or router for internet and TV.
- A portable hard drive that has movies on it.
- Players and other similar devices.
- Set-top box for television from the Internet or from the provider.
- Devices on Android OS.
- Laptops, ultrabooks, chromebooks, netbooks and other types of computers.
You can also use various HDMI converters, which are easy to find in the hardware store. They usually have an HDMI input on one side and a USB input on the other. Some devices may require drivers.
Not that everything was better before, but clearly easier.
The abbreviation HDMI stands for High Definition Multimedia Interface, that is, a high-definition multimedia interface.
By connecting the monitor via HDMI, you can find that the image is very blurry, does not occupy the entire screen area - there are black stripes (fields) along the edges and there is no required clarity.
Moreover, we see such a picture both during boot, and in the BIOS, and in Windows.
First of all, we make sure that the HMDI cable is in good condition and its length should not exceed 5 m.
Disable autoscaling on the monitor.
You may have to select the "Fit to screen" option in the monitor menu.
If the computer has a video card, built-in or external, AMD Radeon, then we try to fix the image using the AMD Vision Control Center (Catalyst Control Center) drivers.
We find the item "My Digital Flat-Panel" and select the sub-item "Scaling Options".
A slider will appear, which must be moved to zero.
The image should now be back to normal.
If you update or reinstall drivers, you will have to repeat the procedure.
If you have an Nvidia video card, then you need to launch the Nvidia Control Center (Nvidia Control Panel) by clicking on the tray icon or by right-clicking on the desktop and select the appropriate item.
When connecting the TV to the computer, the TV and the computer must be turned off, only then connect the HDMI cable.
Turn on the TV first, then the computer.
Switch the TV to HDMI signal display mode.
Modern flat screens are able to display an image without distortion over the entire surface, including the edges.
Yet many televisions use what is known as Overscan technology: the image is electronically enlarged by approximately 5% and cut off at the edges so that LCD and plasma televisions show the same part of the image as CRT.
As a result, the number of pixels of the video card and the screen does not always match - the sharpness of the image deteriorates.
In this case, even the "Taskbar" of Windows may be in an invisible part of the screen.
Most TVs allow you to disable this zoom.
On some models this feature is called "Underscan", on others "Only Scan" or "Pixel for Pixel".
But it also happens that the Overscan function is always active when connected via HDMI and DVI.
Many graphics cards smooth this out by reducing the overall image.
At the same time, the entire “Desktop” of Windows fits on the screen, but, unfortunately, pixel-perfect image transmission is impossible.
Thus, TVs with a switchable Overscan feature are preferred.
If no monitor is connected to the computer, you may see that the resolution on the TV does not match the screen or remains black.
Connect additionally to the system unit via VGA or DVI monitor.
It will show the image and this will allow you to set the correct resolution for the TV in the video card driver.
Finally, if the previous options did not help, try connecting the TV via a DVI -> HDMI adapter to the DVI output of the video card, but the sound will have to be connected via a separate cable to the TV or output from the computer to the speakers.
1. Make sure your computer and TV are turned off.
1. We connect one end of the HDMI cable to the TV in the HDMI connector, the other to a laptop or desktop computer.
2. Turn on both devices.
3. On the TV, you need to select the signal source.
There must be a special button on the remote control, usually it is labeled INPUT or SOURCES or HDMI (see the instructions for the TV).
Click on it and select the HDMI connector to which you connected the cable as the source.
4. On the computer, press the +[P] keys simultaneously. 5. In the “Project” window that appears, select the type of projection, depending on your preference:
- Computer screen only (Display desktop on first screen only)
- Repeating (Duplicate screens)
- Expand (Expand screens)
- Second screen only (Display desktop on second screen only).
You may need to adjust (change) the screen resolution on your computer to a resolution supported by your TV (see your TV manual).
If you do not synchronize the image extensions on the monitor and TV, then on one of the devices it may turn out to be cut off.
6. Confirm the changed parameters "Apply" - "Save changes" - "OK"
7. For the correct sound connection, you need to right-click on the sound control icon on the taskbar (notification area - tray) in the computer and select "Playback devices".
“What progress has come to ...”, - I want to sing, looking at the shelves of modern digital technology supermarkets. The age of new technologies is constantly changing everyday life, and today you can watch your favorite movie not with a nasal pirated translation, but in high quality HD or Blu-Ray. All you need is HDMI outputs on your TV and computer.
The first thing you need is an HDMI cable. Often it comes with a TV set. If not, you can buy a cable at any audio/video store. Consider in advance how long the cable you need. On the latest generation TVs, there are several HDMI connectors on the back. Connect one end of the cable to HDMI 2 and the other end to the HDMI connector on your computer or laptop. Don't worry if instead of the picture you want, you see a warning on the TV screen that the cable was not connected or there is no signal. How to proceed in this case is shown on the example of Samsung TVs. Find the Source button on the TV remote control and select HDMI 2 from the list provided. Perhaps at this stage the issue will be resolved, and the image will appear on the TV screen. If nothing has changed, go to the settings of the computer (laptop) - right-click on the free field of the desktop. A window will appear in which you need to select "Screen Resolution". Pay attention to the line "Multiple screens". If it has the option "Display desktop on 1 (2) monitors only", change it to "Duplicate these screens". In the "Screen" item, the inscription "Multiple monitors" should appear.
An urgent problem for many users today is the expansion of 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 what the negative sounds from the lips of the owners of computer equipment.
In this article, the reader will get acquainted not only with the method of connecting an additional display to a PC or laptop, but also learn about the correct hardware settings. He will also be interested in the recommendations of experts in the field of IT technologies.
About the goals pursued
The larger the diagonal of the LCD screen, the more comfortable viewing of multimedia and better image detail in games and software. A movie 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, the advantages of using such a symbiosis are many, and all of them relate to the comfortable work or leisure of the user.
In recent years, many users have become interested in Internet TV. Why pay money to the provider if you can watch your favorite channels for free from the official website of the TV company? Therefore, the question: “How to bring a computer to a TV?” is being heard more and more in the media. That's just with ready-made solutions while things are bad.
Capabilities of computer hardware
It is 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 a computer. You can only connect to a TV if you have the appropriate digital video output on your PC. Therefore, the user needs to familiarize himself with all the outputs of the system unit and find the right port. It can be located on a video card or on the motherboard of a computer and on one of the ends of a mobile laptop.
There are devices that do not have an HDMI connector. It is quite possible to find on the old video output VGA (D-Sub) or DVI digital ports with DisplayPort. Here everything already depends to a greater extent on the TV, in which similar inputs should be present. Having picked up the right cable for the 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, the factory is not limited to one port and provides the user with the opportunity to connect several sources to output an image via HDMI.
Large LCD displays have a slightly different problem. We are talking about the resolution of the reproduced picture 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 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 often wonder why the computer does not see the TV via HDMI. Everything is explained simply - it is impossible to connect equipment of different generations by combining an analog and digital signal 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, there are ready-made solutions at foreign auctions that can 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 what attracts potential buyers. All the necessary cables for video transmission are always included with the converter, so the algorithm for solving the problem is simple: we buy a converter and connect the TV to the computer via HDMI.
When there is no required interface
Not all computers and TVs have an HDMI port - that's a fact. But you should not get upset ahead of time, since with obsolete devices the problem can always be solved. The fact is that the old equipment is focused on the transmission of an analog signal. Although this technology lags behind in terms of image quality, however, 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 only needs to buy a cable for the TV and connect both devices. There are many inconveniences that users will have to face. First, you cannot transmit sound 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 way to buy cable
Users can also experience problems when choosing the wrong HDMI cable. The fact is that a digital video signal is not capable of being transmitted over long distances over a 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 laying) and find a cable of the appropriate length on the market. Yes, it is customary to purchase wires from buyers with a margin, but it should be small, since often the surplus is rarely in demand - more often they simply collect dust at the TV or at the computer. The main thing here is to find the golden mean in terms of the ratio "cost - cable length".
Real offers from manufacturers
It is not easy to choose a cable for a HDMI-HDMI TV on the market. Any buyer can verify this on their own, 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 in this, but, as practice shows, 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 it copes with the tasks set by 100%.
Physical connection of two devices
This article is not about the potential difference from the school physics course, but the user still needs to know that there is a small electric charge on the video ports when the equipment is connected to the mains. Naturally, when connecting two devices, a technician with a large charge will transfer energy through the cable to the port of the connected device. Often, a TV turns out to be more powerful, which, when connected, burns the output on the computer's video card. Therefore, before connecting the computer to the TV via HDMI, you need to de-energize one of the devices (remove the plug from the outlet). Naturally, this problem bypasses all users who have grounding in the house.
Another trouble that the buyer may encounter is the lack of a video signal when connecting the cable, or the transmission of an image with noise. No need to touch the settings of the TV or computer - in 99% the problem is in a low-quality cable. Need to replace it. 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 remote control of the device and select the desired signal source. All ports on the TV panel are registered and numbered, so it remains only to combine the software with the hardware. You don't have to wait for the PC image to appear on the screen right away. The main thing here is to bring the display into readiness for receiving a video signal. This completes the setup for connecting the TV to a computer via HDMI. It remains only to configure the video output of a PC or laptop.
Many users own 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 swap the HDMI cable when working with a computer, so another solution is proposed. The video signal from the laptop can be sent 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 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 technology, the more effective the automatic tuning is - often via HDMI from a computer to a TV, the signal is transmitted 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, you do not need to try to get the TV to work correctly from the remote control, only fine-tuning the video card will help here. The main thing is to always remember that you do not need to change the global parameters, but only one port, otherwise, by negligence, you can destroy the signal to the PC monitor, which will be very difficult to restore.
Working with drivers
Making the TV work like a computer monitor via HDMI, although difficult, is quite realistic. There are many ways to do this, which the reader will have to get acquainted with. Owners of the Windows operating system versions 7.8 and 10 need to go to the control panel and select the "Screen" item.
By going to the "Screen Settings" tab, the user will find that the operating system has already detected the connected TV, but the image is not yet transmitted 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 prompted to choose:
- 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. Manual port assignment for video output is not required by users.
Features of driver settings
Sending a signal to a TV is easy, but adjusting the picture quality and transmitting 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 that you navigate by 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 place the icon No. 2 with the mouse relative to the icon No. 1 so that it is convenient to move desktop objects between displays.
The second step is to adjust the resolution of the TV screen. The main thing here is to choose a parameter that is supported by the connected display, otherwise a failure will occur and the video output port will turn off. By clicking the "Advanced Options" button, the user can choose the refresh rate of the display, 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 a high-quality image, but also sound, but there is no corresponding setting in the display resolution settings. With the transfer of audio, everything is simple - at the hardware level, the sound goes to the additional screen along with the video. That is, it is enough for the user to move the video player window to the TV display with the mouse. The computer speakers will be muted and the TV speakers will be activated.
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 fail, they simply do not have enough power to process digital video and high-quality sound.
Alternate Driver Setting
Not only Windows tools can set up video transmission to the TV screen. Owners are given the opportunity to ensure high-quality transmission through the 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 have problems that they try to solve together in the media. Most of the negative reviews are related to the low quality HDMI cable that was purchased at foreign auctions or in stores at a low price. A greedy person pays twice - all users who decide to save money on buying an HDMI cable should know about this.
After adjusting the display settings and saving, the image on the main monitor disappeared? This is the second problem that users often have to face. The reason is quite simple - the parameters of the main monitor have changed. There is only one recommendation - connecting the TV to the computer, you need to control your actions. Number 1 in the system is always the main monitor - its settings cannot be changed. With the rest of the numbers (2,3,4) you can do whatever you want.
Finally
Yes, in order to create convenience for themselves, the user needs a little time and investment. It simply cannot be done without it. There is an instruction in which all the actions are prescribed, they must be clearly followed:
- 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 perform 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 fine-tune.
