We use a laptop as a computer monitor. How to connect a computer to a TV? Wired and wireless methods How to watch and play using hdmi

Hello everyone! The “seven” has many of its own “proprietary” problems, which ordinary users are not always able to deal with. But we will help you with this! So, the topic of today's lesson is setting up an HDMI cable.

  • We will look at how to connect the cable;

  • What settings in Windows need to be activated;

  • At the end of the article there is a detailed Video instruction.

After you have connected the HDMI cable to your laptop/computer and TV, right-click on the “Desktop” and select “Screen Resolution” from the drop-down menu. By the way: the moment you connect the cable, you will see a window in which the “Screen Settings” field and a circle, divided into two parts, with digital designations 1 and 2. Set the settings in the required fields, such as: “Screen ", "Permission", etc. Next, in the “Multiple Screens” field, set the “Duplicate these screens” function. Now click on the “Apply” and “Ok” button. This way you activate all the necessary settings for an adequate image.

Let's move on to the sound settings on the TV: these settings are made on the computer! Click on “Start” - “Control Panel”. In the system settings window that opens, select “Hardware and Sound”. Click on it and select the options “Sound” - “Manage sound devices”. By clicking on it, you get a separate “Sound” window. In this window you should see an icon for the TV connected to your computer, for example “Samsung”. A little lower in the same window you will see the “Speakers” option. We move the cursor over the TV icon (namely the TV, not the speaker) and right-click. A menu will appear in which we select the line “Use as default”. Attention: if everything was done correctly, a green “bird” should appear in the window near the TV. If you want to turn off the sound, you can turn it off in the “Speakers” window: right-click, select the “Set as default” line and click on it. This is such a strange pattern. However, this is how things work. Click “Apply” and “Ok”. By the way, it’s probably no longer a secret to you that you don’t have to buy a GPS navigator if you have an Android phone, all you need is

I answer all questions in detail.
Friends! Everything you do on the computer, watch movies, cartoons, chat on Skype, play, view photos, slides or Internet pages in a browser, all this will be shown on the screen of your TV if the TV is connected to the computer via an HDMI cable. Nowadays, almost any TV has an HDMI input, and most produced video cards have an HDMI output.
The HDMI interface was invented in order to connect two high-tech digital devices (which are undoubtedly your computer and TV) and transfer information from device to device without loss of quality. Such transmitted information can be an image and multi-channel high-quality sound. If you have a movie or cartoon on your computer, in any HD, Blu-ray or AVI, MOV, MPG, MP4 format, then you can watch it all on your TV. There are slides or photos, please look. I’m not talking about games, because I’m not a supporter of them; they take up a lot of time from young people, which can be spent on studying. We connect the TV to the computer via HDMI with a second monitor To connect the computer to the TV we will use an HDMI cable, it looks like this and can be up to 20 meters long, choose the cable of the length you need.

For example, let’s take a Samsung TV, a not entirely new 4 series (LED type), purchased several years ago, but it already has two connectors for connecting HDMI devices.

The computer that we will use to connect to the TV was also purchased about three years ago, it has an Nvidia video card installed and also has an HDMI connector.

As I already said, our TV has two HDMI connectors. With the TV turned off, connect the HDMI cable to the HDMI 2 connector,

We connect the reverse end of the cable to the HDMI connector of the video card of the desktop computer. The computer, in turn, is already connected to the monitor (also Samsung SyncMaster 971P) with a DVI cable.

We turn on the computer and TV. There may not be an image on the TV right away, instead we see the following message: “Cable not connected” “Check cable connections and source parameter” or “Weak signal or no signal”

On Samsung TVs, to display a list of all available video sources, you need to press the Source button on the remote control.

A menu appears on the TV, in this menu, using the remote control, select the HDMI 2 connector,

Now, on our TV, an exact copy of our computer’s desktop should appear. But again there is nothing, the same error appears on a black screen. So we go to the “Screen Resolution” settings. Right-click on the desktop and select “Screen Resolution”.

As we can see in the window that appears, our main screen is set to the second (2) Samsung SyncMaster 971P monitor, and in the “Multiple Screens” parameter we have set “Display the desktop on only 2 monitors”, which is why the image is only present on the computer monitor screen, but it's not on the TV


We bring everything in this window to this state. Select a parameter
Multiple screens: "Duplicate these screens"
In the “Screen” parameter, “Multiple monitors” is automatically set, click Apply and OK.

The desktop of our computer appears on the TV.

The resolution of our small Samsung TV is 1366 x 768. If your computer monitor supports this resolution, then it will automatically be set to the same resolution of 1366 x 768. If not, then either the TV or monitor will have the wrong resolution. For example, my Samsung SyncMaster 971P monitor has a maximum resolution of 1280x1024. When using a TV and a computer monitor at the same time, the main thing for me is to set the resolution on the TV correctly, otherwise why would I connect it then. I set the resolution to 1366 x 768 on my Samsung TV, the image is perfect.

And on a computer monitor such a resolution of 1366 x 768 looks like this.

And nothing can be done here. If you want the perfect image on your TV and computer monitor, then they must support the same screen resolution, that is, have the same characteristics. There is no sound on the TV after connecting the TV to the computer via HDMI Friends! Don't forget that the HDMI interface transmits video and sound over one cable, and we can specify in the operating system settings to use the TV's built-in speakers for sound output.
Let's fix the problem by using a TV instead of a monitor. Go to Start->Control Panel->

Hardware and Sound->Sound

If you don’t have anything in this field, right-click on an empty space and in the menu that appears, check the “Show disabled devices” items. "Show connected devices"
Now we look at the name of our TV, in my case it is Samsung, we need to turn it on and turn off the rest. Right-click on Realtek and select Disable.

We also turn off the speakers.

Samsung – Enable, Apply and OK.

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 terms of 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 - 99% of the time the problem is a low-quality cable. It needs to be replaced. In general, experts recommend checking the HDMI cable directly in the store to avoid connection problems.

TV settings

It will not be difficult for the owner of 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 will complete the setup of connecting the TV to the computer via HDMI. All that remains is to configure the video output of your PC or laptop.

Many users are owners of home theaters and other video and audio equipment that is connected to an LCD TV. Naturally, a situation may arise when 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 technology, the more effective 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:

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

Driver configuration features

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

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

Tricks with sound transmission

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

It is worth noting that a mobile device or computer is capable at the hardware level of supporting several video devices connected via HDMI, 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).

Finally

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

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

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

To do this, inspect the connectors available on the device. If you cannot determine the types of ports by eye, find their description in the documentation for your computer. Depending on the device model, you may see the following types of connectors:

  • HDMI is a digital interface that is present on most modern computers. It transmits both audio and video, and therefore is optimal for outputting a multimedia signal to a TV.
  • DVI is another digital port that is widely available on the market. It transmits only video, no sound.
  • VGA is a popular analog connector. Like the previous type of port, it outputs only a video signal.
www.amazon.com
  • Mini DisplayPort, Thunderbolt 2, USB-C and Thunderbolt 3 (USB-C) are digital interfaces that are present in Apple computers. They all transmit video and sound. In addition, the Mac may be equipped with a regular HDMI connector.

There are other types of connectors. But we have listed the most popular ones. Surely your device is equipped with one or more of them.

2. Determine which connectors for signal reception are on the TV

Inspect the TV ports. Most modern models have HDMI and VGA connectors. Older ones are equipped with RCA format ports, the plugs for which are called tulips:

3. Select a cable according to the available connectors

If you have an HDMI TV

If both your TV and your computer have an HDMI connector, then everything is simple: you can connect the devices using an HDMI cable. This option will be optimal.

To connect a computer that does not have an HDMI port to an HDMI TV, you will also need a special signal converter along with an HDMI cable. Which one exactly depends on the connector available on the computer. This could be DVI → HDMI, VGA → HDMI or other adapters to HDMI.

In addition to the HDMI cable, such converters can often be connected to an additional audio cable, the other end of which is inserted into the computer. This allows audio to be transmitted bypassing the limitations of DVI and VGA. An audio cable is often sold complete with a converter.


www.amazon.com

To connect to a Mac HDMI TV with Thunderbolt 2 or Mini DisplayPort, you will need a Mini DisplayPort to HDMI adapter along with an HDMI cable. For it to transmit sound, ask the store for an adapter that supports audio.

If you have a VGA TV

For a VGA TV, the procedure will be similar. Only you will need an HDMI → VGA, DVI → VGA or other converter, depending on the computer port. The main thing is that it converts the signal to VGA.

If you have a TV with an RCA connector

If you have a very old model of TV with tulips at your disposal, then converters like HDMI → RCA, VGA → RCA and others that provide an RCA signal at the output are suitable.

In order not to make a mistake when buying a cable or converter, you can tell the seller the types of connectors on your TV and computer: he will select the appropriate option for you or check the compatibility of your choice.

4. Connect devices via cable

Turn off your computer and TV first for safety reasons. Next, connect the devices using a cable (and, if necessary, a converter). Only then turn on the devices. If the TV does not automatically detect the computer as the signal source, then do it yourself in the TV settings.

5. Adjust the TV picture using your computer

If the image is blurry, open the system settings on your computer and find the section responsible for the monitor. Here you can set the resolution that matches your TV and change the video display mode if necessary.

How to connect a computer to a TV via Wi-Fi

Modern smart TVs can be connected to computers wirelessly via a local Wi-Fi network. Technologies like DLNA and Wi-Fi Direct allow you to broadcast video, music and other content to your TV screen or completely duplicate the image from your computer on your TV, turning the latter into a wireless monitor. Moreover, in the case of Wi-Fi Direct, you don’t even need a router for this.

For example, on LG devices there is a service for similar functions. And Samsung TVs offer similar capabilities as part of the AllShare service.

Wireless connection settings may vary depending on the manufacturer and model of your TV. Some devices establish a connection in semi-automatic mode. Others require installation of additional software on the connected computer.

Therefore, it is difficult to formulate universal instructions that will suit all users. If you want to connect your TV to a computer via Wi-Fi, you will find the necessary information in the paper manual or on the manufacturer’s official website along with the software required for this.

In the case when Wi-Fi Direct is not configured, Miracast is not supported, there is no flash drive with a large capacity, but you really want to watch a movie in good quality, we remember the HDMI connector - a great way to duplicate an image on another device without losing quality. Therefore, the question arises: how to connect a TV to a computer via HDMI in Windows 10 and what is required for this? The answer is below.

What do you need to connect?

To connect we need:

  • laptop or desktop PC with HDMI output;
  • TV with HDMI input;
  • reversible HDMI cable.

Attention! To get a high-quality picture with an audio track, do not use adapters from HDMI to DVI and VGA, otherwise watching movies and photos will only leave negative emotions.

How to connect a computer to a TV

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


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

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


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

To enable it you need:

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

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

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


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