We all love to watch good movies. And if earlier, at the beginning of the week, we would pore over the program schedule, circling the points that interested us, afraid of missing out on something interesting, but today the Internet allows us to select the program independently, to the taste of each of us at any time.
This is very convenient, but watching movies on small monitors does not bring as much joy as on large TV screens. Therefore, these devices began to be combined into one home theater system. But it often happens that when connecting a laptop or personal computer to a TV, a problem arises, and after connecting there is no sound through the hdmi cable.
The main purpose of this material will be to identify the cause of the malfunction and consider some ways to eliminate this problem. But first, let's figure out what an HDMI cable is: in what cases it is worth using, in what cases it is not necessary, and how to connect correctly (see).
HDMI cable
HDMI is a modern standard cable designed for high-speed transmission of high-quality digital audio and video signals:
- The cable design features protect the transmitted information from possible copying, but this is more of an informational addition that is not useful to the average user.
- Before HDMI, a DVI cable was used to transmit a digital signal, which is still used today when connecting computer equipment, but unlike its predecessor, HDMI has more compact dimensions and is capable of transmitting sound, which contributed to the rapid introduction of this standard into consumer electronics.
- These cables are used to connect not only computers to the TV, but also: projectors, photo and video cameras, DVD and Blu-Ray players, satellite receivers, modern game consoles and other digital equipment.
Advice! If the paired devices in your multimedia system have HDMI outputs, but for some reason you never used them, then be sure to purchase this cable. You will immediately notice the difference in image quality with the naked eye.
Cable types and properties
What is notable about this standard is that full compatibility cables different generations. But, nevertheless, each model has its own characteristics, which distinguish it from its predecessors.
All cables produced today differ in manufacturing standards. That is, in fact, we have several types of HDMI:
- Standard (Standard) - a model that supports video transmission with a resolution of 720p or 1080i. The maximum throughput is 4.9 Gbps, and the color depth is 24 bits. Essentially, it is budget solution, since the price for a 1.5 m cable does not exceed 300 rubles. Suitable for most undemanding users, or when connecting devices that are not capable of producing a higher quality picture (receiver, DVD, etc.)
- High Speed) - has a throughput of 10.2 Gbit/s, and supports 48-bit color. Goes well with 3D and Deep Color technologies. It has a reverse audio channel for data transmission without using an S\PDIF connection. It is used when connecting to high-speed devices such as Blu-Ray, as it is capable of producing images with a resolution of up to 4K (4096x2160 pixels).
- Standard with Ethernet— this cable is similar to the first one on our list, but has a separate channel for transmitting data via Ethernet (Internet connection). Like any Internet cable, it provides bidirectional data transfer at speeds of up to 100 Mbit/sec. Another difference from the standard version is support for reverse audio channel.
- High Speed with Ethernet— we think everyone has already guessed about the capabilities of this model. It’s only worth noting that it has maximum capabilities for cables version 1.4 (we’ll talk about versions below).
- Standard Automotive- a very specific cable, which is mainly used by professionals when connecting devices that transmit signals via HDMI to a car multimedia system.
Attention! It makes sense to use Ethernet-enabled cables only when both connected devices support this technology. In this case, you can not only organize a high-speed Internet connection, but also transfer content to other connected devices.
HDMI cable versions
The listed types are not the only criterion by which HDMI cables differ. The development of a unified digital standard began with such eminent companies as Sony, Phillips, Thompson, Hitachi and others. The result of the joint efforts of these companies was the HDMI cable version 1.0, which was released back in 2002.
- This development became a breakthrough in the world of electronics, and very soon it firmly occupied its niche, gradually displacing all other connection formats.
- The advantages of the new product include not only a new level and image quality, but also ease of connection - one cable replaced entire bundles of wires, which is especially noticeable when connecting speaker systems with multi-channel sound.
- Over time, the HDMI format received a new impetus for development. Developers began to produce more advanced versions of wires, giving them new functions and capabilities. But, what’s especially nice is not forgetting to keep new versions compatible with old devices.
Today, the most advanced version is cable version 2.0, the capabilities of which are disproportionately higher than those of its “first ancestor”. This standard incorporates all the advantages of previous versions.
Now HDMI wires can not only transmit images and sound of the highest quality, but also, for example, control consumer electronics, transmit a 3D signal, connect TV to the Internet, synchronize video and audio streams, and much more.
Advice! If you are interested in the complete specifications for all versions of HDMI cables, then look for tables and diagrams on the Internet. If possible, we will try to post it as soon as possible this information on our website.
Types of connectors and cable lengths
Despite the general trend towards standardization, the use of any connection format cannot remain unchanged. This fact is due to the fact that most modern electronic devices have become noticeably smaller, moreover, powerful smartphones, tablets and compact computers have become firmly established in our lives, which led to the development of new standards that could allow them to be connected to TVs.
As a result, new types of HDMI cables were developed and released, with specific plugs, for certain types of tasks and devices.
According to the new specification, their number was five, which received the code designation in capital letters Latin alphabet:
- Type A (Standard)— this designation was given to the first connector that we discussed earlier;
- Type B- less popular than the previous type, although it has an expanded channel for transmitting video with a resolution of 1080p;
- Type C and D- mini and micro connectors, respectively. In essence, they are a smaller copy of type “A”, and are designed to connect compact digital equipment (tablets, laptops, etc.);
- Type E— the connector design has a special lock that secures the cable in the socket. Most often, it is used in automotive systems subject to constant shaking and vibration.
One more important information can be extracted from the specifications for HDMI cables - the length of all cables is strictly regulated. The minimum wire size is 0.75 meters and the maximum is 10 meters.
If you are offered a cable version 1.4 larger size, then remember that this option is not regulated by standards, and most likely it will not be able to produce a picture of the required quality. This means that those who like to buy wires with a reserve will not be able to roam around here, because when connected, such an HDMI will lose and distort the signal.
But don’t think that cable size is the only thing that affects picture quality. This factor also depends on the material from which the wire is made. Also, the thickness of the cores also affects - in higher-speed models, they are larger in diameter. But if you still need to run the cable over a long distance, then consider using a signal amplifier that will prevent you from losing it.
Summarizing this chapter, we emphasize that the use of expensive metals in production greatly affects the final cost of the product. For example, there are models whose price exceeds 7 - 8 thousand rubles. Therefore, when choosing a cable, you must first focus on your needs. We'll tell you how to do this further.
Choosing an HDMI cable
We cannot say with complete confidence that this material is a complete instruction for choosing a cable. Rather, these are a few tips and notes that may be useful to you when purchasing, and not become a victim of some unscrupulous seller.
- Let's start with the fact that, despite the specification requirements, HDMI cables can be significantly longer than the values mentioned above. But it is worth knowing some of the features of its design.
- As already mentioned, a cable that is too long loses the signal and distorts it at the output. To prevent this from happening, use HDMI equalizers (amplifiers), or use a specially designed unidirectional cable that has a built-in repeater that replaces a separate amplifying device. In addition, the cross-sectional diameter of the conductors of such cables must be larger than that of standard ones.
- There is some unspoken standard for the ratio of lengths and diameters of the conductor: 5 m - 28 AWG (0.321 mm); 10 m - 26 AWG (0.405 mm); 15 m - 24 AWG (0.511 mm); 20 m - 22 AWG (0.644 mm), etc.
- AWG is an American wire sizing standard in which larger values mean smaller wire diameter. This is the most common marking, but for convenience we have added values in the usual mm.
Connecting audio from your computer to your TV expands its capabilities, improving the sound quality of music or movies. There are several ways to do this, they all have their pros and cons, so it is necessary to give preference to one method or another, taking into account the characteristics of the equipment and its capabilities. Before you connect audio from your computer to your TV, you need to make sure that your devices have one of these connectors.
Main types of connectors
Almost all modern technology is equipped with one of these types of connectors. They are designed for connecting external storage media, video and DVD players, as well as other digital equipment, which includes a computer.
The most used types of connectors are:
- HDMI;
- Wi-Fi;
- RJ45;
Ways to connect sound from a computer
Via HDMI connector
Audio output through this connector is the most popular, since problems and malfunctions are less likely to occur with it, and the sound quality remains good. This cord can be supplied either with some digital devices or sold separately.
Advice
There is no need to purchase an overly expensive cord, since regardless of the price, the same materials are used in its manufacture, which do not change the sound quality.
To connect your TV to your computer, you first need to disconnect both devices from the power supply and then connect them using a cord. This connection method does not require any additional settings, just indicate on the TV as the source HDMI audio exit.
Possible problems when connecting devices
- If the sound is not played, then you need to use your computer to set the TV as the sound source. To do this, right-click on the sound icon in the lower left part of the taskbar and select “Playback devices” from the pop-up menu. From the list you need to select your device, right-click on it and check the “Set as default” menu item.
Important!
When setting up, the devices must be connected to each other. If the computer does not see the TV when the HDMI cable is turned on, then you need to restart it and repeat the setup procedure again.
- You also need to make sure that the video card supports audio playback via the HDMI output. Often everything modern devices equipped with this function. However, some of them include a special jumper that helps create a connector for connecting the SPDIF out connector on the motherboard with the SPDIF in connector on the video card.
- You can solve the problem if you reinstall or update the drivers for the video card.
How to connect sound from a computer to a TV via a Dvi cable?
The second most popular method, which is used when it is impossible to connect via HDMI output. Connectors of this type are divided into three types: digital, analog and combined. However, transmitting sound through this connector is not as simple as with the previous one, since it all depends on the video card used in the computer, because not all of them support audio playback through the DVI output.
In the case of transmitting not only audio, but also video signals to the TV, you must use a DVI - HDMI cable or connect devices using DVI-D - HDMI adapters, and then an HDMI-HDMI cable. This complex connection system is explained by the fact that the video signal does not always pass through the DVI cable.
The disadvantage of this method is also the complex setup process compared to the previous option. To begin, in the TV menu you need to select the DVI connector as the signal source, and the computer and TV must be connected to each other.
Connection via VGA cable
This is an outdated method that is inferior to the first two in terms of ease of connection and playback quality. Therefore, it is often used in older devices where it is not possible to connect using other cables.
What problems may arise during connection?
Very often, the VGA output is already occupied by a computer monitor, so in order to connect another device you need to purchase a special adapter, and then a cord for audio playback.
Main disadvantages
VGA is not intended for audio transmission, it can only be used as additional element, to which it is necessary to connect a special cord. This option is not only costly, but also more complex and of lower quality compared to other methods.
How to transfer sound from a computer to a TV via WI-FI
This method places additional requirements on the TV - support for DLNA technology and the presence of a multimedia file player. Modern plasma models are equipped with this function, so this connection method can be considered as an alternative to HDMI.
Connection setup
After making sure that the TV has a built-in WI-FI module, you can start setting up.
- First, you need to configure the router so that it can work in DHCP mode.
Advice
When setting up, you must assign a password that will protect the local network from unauthorized entry.
- In the TV menu you need to find the item “ Wireless connection", and then find your network and log into it using your password.
- To transfer sound to a TV, you need to install a special program on your computer - a media server. This program then allows access to files and folders containing music or movies.
- To switch audio from your computer, you need to open the media server and select Ethernet as the playback source on your TV.
What is the disadvantage of connecting via a WI-FI router?
When playing audio to a TV, there is a large load on the local network, which can lead to slower speeds.
Connection via RJ45
When connecting using this method, a special network cable, which can be found in stores under the name “twisted pair”. As in the previous method, the TV must support DLNA data transmission technology.
It also uses a router, which is configured in the same way as through a WI-FI connection. However, using this device may result in reduced speed. Therefore, it is better to give preference to additional network card.
The setup follows the same principle as via WI-FI, but you need to connect through a media server.
How to output sound from a computer via an RCA cable
This method allows you to connect even the most outdated models of computers and televisions. Such a cable is called a “tulip”; it can have two or three sockets, each of which is responsible for transmitting a separate signal. Yellow – video, white – left channel of stereo audio signal, red – right channel of stereo audio signal.
Devices must be disconnected from power before connection. Then, you need to attach the tulip connectors to the corresponding holes (often color coded). After this, in the computer settings you need to expand the desktop to fit the size of the TV screen, and switch the TV to “Video” mode.
The most preferred methods among all those described above are connections via an HDMI cable and via twisted pair or WI-FI router. It is these options that can ensure sound quality and connection reliability at the proper level.
The video shows in detail how to connect a TV to a desktop computer via HDMI and MPF. First you need to select a cable without adapters and make sure that the necessary connectors are available on the devices. Then the connectors are connected, and the TV and computer are configured.
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 ensures 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. Not only supports audio and video transmission, but can also be used to connect to 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 question the right choice 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 need 3D, then you should choose a cable with a specification of at least HDMI 1.4. In the case where there is none, you will not be able to watch a three-dimensional 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 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 its 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 paired 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 wrong 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 quality images. This applies to both maximum and minimum values.
In addition, it doesn’t hurt to click on the “ Additional options", 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.
Screen mirroring
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, with the mouse you can select the active one on at the moment The monitor on which the application will run.
The OS will automatically number the displays, and familiarize yourself with them serial numbers you can 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
In the event that you do not like the order of automatic distribution of display numbers, you can simply grab them with the mouse and place them on 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 have 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.
Pay attention!
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 the remote control for your TV. 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 you can easily set a different resolution on each of them! This perfect 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.
In conclusion
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)!
There are several ways to connect sound to a TV from a computer; choosing the best one depends on whether the equipment is equipped with certain connectors.
The main method is how to connect sound to a TV from a computer. When transmitting sound through this cable, difficulties very rarely arise, and the quality of the audio signal is very high. Most best option for new TV models. An HDMI cable is often included with various television and audio equipment; it can also be purchased separately.
Connection diagram:
- Disconnect the computer and TV from the power supply.
- Connect the cord to both devices.
This option does not require any additional settings; just select the HDVI output on the TV as the sound source.
Actions:
- Right-click the sound icon, then select the “Playback equipment” tab and select your equipment from the list of devices that appears.
- Key computer mouse Click on the selected option and check the box next to the “Default” tab.
The procedure is performed with the equipment connected to each other. If the HDMI cable is connected to the devices, but the PC does not see it, then you should reboot.
DVI
Another popular way to switch sound from a personal computer to TV. There are three types of connectors:
- Analog connector.
- Digital connector.
- Combo connector.
With this type of setup, the computer video card must support the audio format via DVI. Scheme:
- In the TV settings menu, select the DVI signal converter.
- Connect the cord to the devices.
VGA
This scheme for outputting audio from a computer to a TV is recommended only if the device cannot transmit a signal via DVI. This method is usually used on outdated equipment.
It is a common occurrence that the VGA connector is occupied by the PC screen, so the switch can only be done using a special adapter, and then a VGA cable is connected. This transfer option is considered the most difficult and expensive.
WiFi
This method is only possible if the TV has DLNA support, and a multimedia file player is also required. All modern panels support DLNA, so this method can be considered an alternative to transmitting audio via HDMI. Thanks to this option, the connected screen works directly with PC files. Scheme:
- Make sure that the plasma panel has a module for distribution via a WI-FI connection.
- Turn on devices.

How to solve the problem with no sound on the TV?
Perhaps many people have encountered a similar problem when trying to synchronize these two devices. First you need to find out the cause of the problem. First you need to check the audio playback device on your computer or. Quite often it happens that the TV connected to the computer is not used as a sound playback device, which means it needs to be configured as the default device. This is done as follows: you need to right-click on the sound icon, which is located on the taskbar in the lower right corner and select “Playback devices”. The window that appears will display all playback devices, including the TV itself. Next, you need to select it and right-click, then in the context menu “Set as default”. Once confirmed, the TV should be used as the default audio output device.
Sometimes the TV may not appear in this window. Don't be afraid or panic ahead of time. If your TV is not displayed in the window or has the “Inactive” status, although the hdmi cable is already connected to both devices, just restart the computer with the hdmi cable connected. When the PC starts again, go to this menu again. The TV should appear in the window and become available for use. Otherwise, you will need to download and install special drivers, which can be found on the official website.
If the problem is not solved, try checking the sound, it may just be. The problem may lie in the hdmi cable itself. For example, the wires in it may oxidize or become damaged. In this case, only a new hdmi cable can solve the problem.
