Connecting an hdmi cable to a lg tv. How to connect a computer to a TV? Wired and wireless methods

If you need to connect a second monitor to your computer, but you don’t have one, then there is the option of using your laptop as a display for your PC. This process is carried out using only one cable and minor adjustments to the operating system. Let's look at this in more detail.

To complete this process, you will need a work computer with a monitor, an HDMI cable and a laptop. All settings will be made on the PC. The user only needs to perform a few simple steps:

1. Take the HDMI cable and insert one side into the corresponding connector on the laptop.
2. Connect the other side to a free HDMI port on your computer.
3. If one of the devices does not have the required connector, you can use a special converter from VGA, DVI or Display Port to HDMI. They are described in detail in our article at the link below.



4. Now you should start the laptop. If the image is not transferred automatically, click on Fn+F4(on some laptop models, the button for switching between monitors may be changed). If there is no image, adjust the screens on your computer.



5. To do this, open "Start" and go to "Control Panel".



6. Select an option "Screen".



7. Go to section "Customizing Screen Settings".



8. If the screen was not detected, press "Find".



9. In the popup menu "Multiple Screens" select item "Expand these screens".

Now you can use your laptop as a second monitor for your computer.

Alternative connection option

There are special programs that allow you to control your computer remotely. Using them, you can connect your laptop to your computer via the Internet without using additional cables. One of the most popular programs is. After installation, you only need to create an account and connect. Read more about this in our article at the link below.

In addition, there are many more programs for remote access on the Internet. We suggest that you familiarize yourself with the full list of representatives of this software in the articles at the links below.

Today, almost everyone has large LCD TVs, which have successfully replaced the anachronism in the form of old CRT models. Their huge advantage is not only the highest image quality, but also the ability to connect to a computer. Using a regular laptop, you can make an excellent media center for very little money.

It’s just that, in principle, there is nothing complicated about this, but sometimes there are minor problems that require a little time to resolve. No need to worry, as almost all problems can be solved relatively easily, and the reward for your efforts will be a movie in excellent quality that you can enjoy on your home TV screen!

General information

So, to connect, you need a TV itself that supports this mode, as well as a computer or laptop, which can also be connected via an HDMI connector. Of course, you also need the cable itself. So how do you set up your TV via HDMI? To answer this question, you will have to conduct a small educational program on the most basic concepts.

Types of HDMI connectors and cables

By the way, what is this? This is a relatively new interface for transmitting high-definition video and audio. Its peculiarity is that it uses exclusively digital transmission of encoded data, which provides excellent picture and sound quality. It is not surprising that this interface is one of the most popular in the world today.

There are three types of standard HDMI connectors:

• Type A. Standard, found in any modern technology.
• Type C (micro HDMI), as well as Type D (mini HDMI). These connectors are familiar to all owners of modern cameras, smartphones and tablets. Being smaller, these modifications have all the advantages of their predecessors.
• Type B. It differs in that it is capable of transmitting video with a resolution higher than 1080p, but is still rare.

Of course, among such a colorful “hotbed” of connectors themselves, no less varieties of cables have appeared that can connect them:

• Standard. It is most common and can be used to transmit video with a resolution of up to 1080p.
• High speed. You can watch 3D and other ultra-high definition formats.
• Standard/Ethernet. It not only supports audio and video transmission, but can also be used to connect to a local network. Rare, however, as are devices that support this feature. In any case, connecting a computer via HDMI to a network is almost impossible to see in our country.
• High Speed/Ethernet. Everything is the same as was said regarding the modification described above, only it is even less common and supports all high-definition video formats.
• Automotive. As the name suggests, it is used to connect devices that support this interface in cars.

Choosing a cable

Beginners usually have difficulties not only with how to connect a computer to a TV via HDMI, but also with the issue of choosing the right cable. What you don't hear in stores! And about oxygen-free copper and gold-plated contacts! Some of these stories are relatively true, but you definitely shouldn’t believe everything.

So, remember one simple rule: if you are not going to watch 3D movies on TV, and the cable length in your case does not exceed 1.5-2 meters, you can take any model, even a Chinese one. In this segment there is no difference between a cable that costs six thousand and one that costs 200 rubles. If you just need 3D, then you should choose a cable with a specification no lower than HDMI 1.4. If there is none, you will not be able to watch a 3D movie via HDMI, since the cable simply cannot cope with such a volume of transmitted information.

However, even then you shouldn’t run to the store to buy a cable, paying 500 or more (!) dollars for it. Any cord of the required specification will be sufficient. Forget about the myths that talk about “better signal transmission” and other nonsense. The specificity of digital transmission is that it either exists or it doesn’t exist at all. Simply put, if the cable is capable of transmitting a signal, then it will transmit it in any case, and the quality of the image and sound will not suffer in any way. But when the computer stubbornly does not see the TV via HDMI, it still makes sense to replace the cable. It may happen that it was manufactured in violation of technology.

And now a few words about where the connectors are.

If we talk about a TV, then most often they can be found on its back panel. However, in the latest models, HDMI connectors are often located on the side wall. It's easier with computers. All necessary inputs are on the video card. If we are talking about a laptop, then in the standard case the desired input is located close to the USB 3.0 connector. Before connecting your laptop via HDMI, it won’t hurt to look at the instructions for it again. It will also not be superfluous to visit the manufacturer’s website, where you can familiarize yourself in detail with all the specifications that this device uses.

Connection

So how to connect your computer to your TV via HDMI? Everything is very simple here. Connect the plug to the connector on the TV, and then insert the other end into a similar port on the computer’s video card. Attention! Both devices must be turned off at this moment, otherwise they are likely to break!

Here's how to connect your computer to your TV via HDMI. If only one TV is connected to the computer, then everything should work immediately after they are turned on. But if you need it in conjunction with a monitor, then numerous and varied problems are possible, the occurrence of which is associated with several factors at once.

Connection problems

So, at first you may find that all the icons and controls on your TV screen appear stretched or warped. This is due to incorrect resolution. As a rule, modern operating systems set the appropriate value automatically, but this is not always the case.

To adjust the resolution, you need to right-click on any free space on the desktop, and then select “Screen Resolution” from the context menu. Keep in mind: it is better to set the recommended values, since otherwise no one can guarantee good image quality. This applies to both maximum and minimum values.

In addition, it doesn’t hurt to click on the “Advanced Settings” button, and then go to the “Monitor” tab. There you should click on the “Screen refresh rate” drop-down list. You need to make sure that under this item there is a checkbox “Hide values ​​that may harm your equipment.”

Important! All of the above especially applies to laptops, in which damage to the screen will lead to the replacement of the entire laptop assembly. Only after you make sure that all parameters fully comply, you can connect the laptop to the TV via HDMI.

The minimum suitable value is 60 Hz. However, the more, the better. Of course, the color rendering quality must be set to 32 bits. If after clicking the "OK" button the system does not work normally, just wait 15 seconds, after which everything will return to the default settings.

Setting up the connection of multiple displays

If not only a TV, but also a monitor is connected to the system unit, the system will consider all devices to be displays. The specific type of equipment in this case is completely unimportant. Windows 7/8 has two main modes for this case: duplication and cloning. You can choose between them in the same dialog box in which you set the required display resolution.

Duplicating screen

As you can guess from the name alone, your two desktops will be displayed in front of you on all connected displays. Important! Alas, standard Windows tools (and Windows 8 is no exception) do not allow you to set your own value for each monitor. Imagine what the image will look like on a large TV and an old 4:3 monitor!

Simply put, to use this mode comfortably, you will have to use devices with the same resolution, since otherwise some display can be turned off altogether. Since we are talking about connecting a TV, this option is still unlikely. However, you can simply pair a widescreen monitor with your TV. In this case, it will be possible to experimentally find the most suitable resolution, and there will be no annoying black bars on the sides of the desktop on the computer.

Here's how to connect your computer via HDMI using this mode.

Expanding the screen

This method is much more interesting. In this case, the TV can be made into one desktop, and the laptop or computer monitor can be made into a second one. Simply put, you can use your mouse to select the currently active monitor on which the application will run.

The OS will automatically number the displays, and you can see their serial numbers in the same “Screen resolution” section. If you have gone too far with the number of TVs and monitors, and therefore no longer understand which one is which, just click on the “Detect” button, after which the devices will be sorted in order, and the currently active monitor (or TV) will be highlighted.

Manual distribution

If you don’t like the order of automatic distribution of display numbers, you can simply grab them with the mouse and put them in the right place. So, it is preferable to place the TV in the front rows, since in this case it will be much more convenient to display content on it. After all this, you can click on “Apply”, after which the desktop will be expanded to multiple monitors. Using the “Make Primary” button you can set the priority.

Roughly speaking, the monitor you select will have a Start button, and all other connected displays will be considered slaves by default. As practice shows, setting the TV as the main monitor is not very wise. Of course, except for those cases when it will “officially” replace your work computer monitor.

Other options

If you installed control programs for your video card (NVidia, AMD), then connecting via HDMI can be done using the methods suggested by their developers. For example, in the first case, you need to right-click on an empty space on the desktop, and then select “NVidia Control Panel” from the context menu that appears. Go to the “Display” section and make the settings you are interested in. AMD programs are managed in a similar way. In general, all setup steps are similar to what we described above, so it won’t be difficult to figure them out.

How to output sound to TV via HDMI

What about sound via HDMI? Don't forget that an HDMI cable is a very functional thing. Not only images are transmitted through it, but also sound. Many novice users completely forget about this, and therefore spend a lot of time trying to fix “problems” that actually don’t exist. For sound to be transmitted correctly, you must have the most current versions of drivers installed on your video card. Of course, the same applies to drivers for audio output devices (the Realtek core integrated into the motherboard or a discrete audio card).

Let's learn how to set up sound via HDMI. To understand whether you have a sound output module installed through it, you need to open “Device Manager”. It's easy to open. Right-click on “My Computer”, select “Properties” in the context menu, and in the dialog box that opens, on the far left side, click on the desired item. A new working window will open in which you need to find the “Sound, game and video devices” section. It should contain a line like High Definition Audio, which indicates support for digital quality audio playback.

Next, go to the “Control Panel” (search through the “Start” button), select the “Sound” item there. It should also have something similar to "HDMI Device". If everything is in order, turn off the computer, connect the TV, and boot the system again. The device should change its status to “Ready”. You need to right-click on it, and then select the “Use as default” option in the context menu that opens.

Note!

Alas, not all models can transmit sound to a TV via HDMI in principle, as this is due to the characteristics of the connectors. As a rule, the first connector, which is specifically designed for connecting computers, laptops and other reproducing equipment, should in any case have such capabilities. In addition, it doesn’t hurt to dig deep into the TV settings. There you can often find a lot of useful things - setting up sound output, for example. However, connecting a TV via HDMI largely depends on the manufacturer and model of the device. Remember this. Therefore, it won’t hurt to read the instructions again.

That's it, after this the audio must go via HDMI. To be sure, reboot the entire system again, and then start enjoying high-definition movies streamed from your computer or laptop. Here's how audio is transmitted over HDMI.

Don't forget about the remote control!

It happens that you have already tried all the methods, but the image stubbornly refuses to appear on the TV screen. Why is there no signal via HDMI? In this case, it won’t hurt to take a closer look at your TV’s remote control. There is probably a small Source button there, with which you can select the signal source.

Click on it, then in the selection menu that appears, activate the HDMI port to which your computer is already connected. Most likely, after such a simple action, everything will work perfectly. Here's how to connect your TV via HDMI.

And again about the problems

Alas, Windows would not be itself if everything was so simple. As a rule, many users encounter problems associated with duplicating images from a PC monitor to a TV screen. So, very often people complain that they are unable to display an image on a TV unless they make it their main monitor. As you can understand, this is not advisable in all cases.

As a rule, a TV is used as a media player, and a regular monitor is used for work. If it is not active, you will not be able to work fully or watch movies normally. Unfortunately, the creators of Windows are once again “behind the times,” and therefore there are simply no standard tools for properly managing a configuration with multiple monitors. We have to look for third-party alternatives.

The most powerful and flexible program of this type is the excellent Actual Multiple Monitors application, which we will talk about now. The program is paid, which is important for our region, but its capabilities are worth the stated price. Of course, there are a number of completely free utilities, but their capabilities are not always comparable to those of the program described below.

Actual Multiple Monitors - assistant in connecting a TV

Of course, when creating this utility, the developers were unlikely to focus exclusively on connecting a TV via HDMI, but the program really simplifies its use when connecting to an existing computer/monitor pair.

Unlike standard utilities, this application can make the desktop on a computer monitor and TV absolutely identical, but at the same time you can easily set a different resolution on each of them! This is an ideal solution for those users who are quite happy with the old 4:3 monitor, but who would like to use a TV as a second display.

But that's not all! You can easily determine which application windows will be displayed where. Simply put, you can only display the window of the player you are using on the TV screen. Agree that this option is extremely convenient and useful! And one more pleasant circumstance. The application allows you to use a separate desktop image for each monitor, which will certainly be appreciated by all aesthetes. The program is paid, it costs around 40 dollars, but it works out its cost in full.

How to connect two TVs if the video card only has one HDMI connector?

If you have the opportunity to connect two TVs to the system at once, one of which will be used for its intended purpose, and the second you will work on, then that’s great... But most modern video cards only have one HDMI connector. What to do in this case?

This problem can be solved in two ways. In the first case, you will need to find a DVI/HDMI adapter. Connect it to the analog output of the video card, and then use a cable to connect the system unit to the TV. However, if you are using an old monitor that is connected to the system unit only via an analog connector, you will not have such problems at all. Important! Through such an adapter, sound is not transmitted to the TV via HDMI, and therefore the issue with acoustics will have to be resolved separately.

The problem is that the quality of the signal that is output to it is not very high. What to do if you have a high-quality monitor and TV that you would like to connect via a normal interface? In this case, you will need to buy a so-called HDMI splitter, which allows you to connect several devices to one output at once.

Important! As with cables, don't try to buy the most expensive products of their kind. In stores you can see models costing $500, but practice clearly shows that they do not have any significant advantages over the “Chinese” ones for 300 rubles. An exception should be made only for cases when you plan to view “heavy” 3D video. If this is really the case, you will have to buy a more expensive model, since cheap modifications rarely support such signal density.

Finally

Here's how to connect your computer to your TV via HDMI. There is nothing complicated about this, you just need to be a little more careful. We warn you once again - all devices must be turned off at the time of connection! It is not uncommon for ports to burn out if this instruction is ignored!

This unfortunate circumstance is due to the fact that this cable is actually under quite high voltage. Surely everyone knows stories about flash drives that caused USB ports to burn. And this despite the fact that the voltage on the ports is negligible (compared to HDMI)!

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 to another device without losing quality. Therefore, the question arises: how to connect a TV to a computer via HDMI in Windows 10 and what is required for this? The answer is below.

What do you need to connect?

To connect we need:

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

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

Connection instructions

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

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

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

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

To enable it you need:

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

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

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

Advice! If you don’t have cable television, and IPTV 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.

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.

If you are planning to purchase or have already purchased an HDTV, you will certainly be faced with the need to choose an HDMI cable. How to connect an HDMI cable to a TV is an interesting question, but first you need to purchase a cable. This is not a very complicated procedure, but you must first familiarize yourself with some of its nuances.

Brief characteristics of HDMI cable

Before connecting an HDMI cable to your TV, it is important to understand their basic characteristics. HDMI is a high-definition multimedia interface. There are two types of HDMI cables: HDMI Standard and HDMI High Speed. HDMI Standard cables are used to connect television receivers of all categories: cable, terrestrial, satellite, including 3D, as well as regular non-3D Blue-Ray players and most HD video cameras. Cables in this category may have different markings, except for High Speed. Game consoles, computers, Blue-Ray 3D players. It is advisable, but not necessary, to connect game consoles, computers, and Blue-Ray 3D players with a High Speed ​​cable.

One of the main subtleties in choosing a cable is the requirement for its length, which should not exceed 5 m, otherwise the image quality may deteriorate sharply. Also, the cable must not be bent. Before purchasing a cable, you need to decide what connectors are on your device. Relatively old models of televisions and other equipment usually have two types of connectors - RCA (otherwise called a “tulip” cable with triple wiring) and S-video, a round output with 4 or 9 pins. Newer device models are equipped with an HDMI interface.

To make the most efficient connection, you need to purchase a cable that, on one side, has a connector available on the device panel, and on the other side, HDMI. Finding such a cable is quite problematic, and if this fails, you need to use adapters that may have two or more connectors of different types.

The process of connecting an HDMI cable to a TV

How to connect an HDMI cable to a TV? Before connecting the cable, the TV must be turned off. If the TV device has S-video, then the cable is connected via the S-video connector to the TV, and HDMI to the computer.

It is not advisable to connect an HDMI TV to the DVI connector of a computer. This connection will result in a significant reduction in picture and audio quality.

After connecting the TV and computer with an HDMI cable, the TV turns on first, and then the computer. When the operating system is loaded onto the computer, the TV screen flashes, which indicates that it is connected to an external source. The TV must be switched to AVI mode, in which the signal will come to it not from an external antenna, but from the computer.

How to connect an HDMI cable to a TV if the TV is connected to a computer using an HDMI cable for the first time? A mandatory procedure is to configure the video card. To do this, you need to find the properties of the video card. When you enter the “Advanced” tab, you will find instructions that will help you get an image of your computer on your TV. In Windows 7, you need to go to “Resolution” - “Find” on the desktop. The TV device will be detected in the system and will remain marked as the main monitor. If the TV is not detected, then you need to go into the properties of the video card again and repeat all the steps again.

In the properties of the video card, you can adjust the resolution, desktop size, adjust the color and other settings.

If problems occur with the image, the cause may be either the HDMI cable or problems with the connected devices, which is most often caused by a software error.
