HDMI does not connect from laptop to TV

Setting up your TV

With the cord plugged into the TV, grab the remote control to open the main menu. You need to switch to HDMI, that is, change the signal source. Each TV set has a different setup menu.

Mostly the signal source is selected in the “External inputs” section or using the “Source” button on the remote control. Prioritize the HDMI connector on your TV with the same number to which the cable is connected. When you are done, the laptop’s desktop will appear on the screen.

Laptop settings

When everything is connected, you can adjust the image quality. This is a mandatory measure if HDMI from a laptop to a TV displays a picture for the first time. Otherwise, the image may be fuzzy, blurry.

Follow the simple step-by-step instructions:

  • Right click on an empty space on the desktop.
  • From the drop-down context menu, select the command “Screen resolution”.

  • By adjusting the screen resolution, you must select the optimal picture quality.

Change the resolution and see how the image quality has improved or deteriorated. There are also several options for connecting to a TV:

  • mirroring the laptop screen to TV;
  • expanding the working area;
  • TV as a second monitor. the laptop screen and TV screen work independently. You can, for example, simultaneously play a movie on the TV and surf the Internet or work behind a laptop screen. This type of connection creates a load on the video card;
  • laptop screen is off, only TV is working.

This completes the setup. Now you can enjoy watching your favorite movies on the big screen. Setting up a connection on a netbook is carried out in a similar way.

What you need to connect a laptop to a TV via HDMI

Before proceeding to consider the question of how to connect a laptop to a TV via HDMI, we will make a list of the necessary devices. You only need three things:

  • HDMI cable;
  • TV set;
  • notebook.

Syncing your TV and laptop is a simple process. You only need to buy a cable that will allow you to duplicate the image on a large screen. It is very rarely included in the basic package. It is inexpensive. The program for connecting to a laptop TV is not required. Therefore, no special skills are required either. Just follow the instructions.

Some TVs and laptops are not equipped with HDMI, but this is very rare. In such situations, you need to buy an adapter for other connectors.

Instructions for connecting a laptop to a TV via HDMI

Not all modern TV models come with Smart functionality. Of course, you can “upgrade” the device by connecting a special console, but there is a cheaper and easier way. It is enough to know how to connect a laptop to a TV via HDMI.

Connecting a laptop and TV is the simplest task. Simply plug one end of the wire into a jack on your laptop and the other into a port on the back or side of the TV. What will it give? Once connected, you can watch movies, TV shows and sports broadcasts on the big screen. In fact, TV will act as a second screen. Everything that you run on your laptop is automatically transferred to the TV screen.

Training

Connecting a laptop to a TV via HDMI is performed as follows:

  • Find HDMI on your laptop. It is usually located on the left or right.
  • Find the connector on the TV through which we will connect the laptop. It is located on the back panel, sometimes on the side. Remember its number, it is usually written in small print next to the connector.

  • Connect laptop and TV with HDMI cable. It is the cord that acts as a connecting element.

When you have connected the cable, the connection is complete, proceed with the setup.

Possible problems

What to do if the resolution setting did not give the expected result. The simplest way is to press the “WinP” key combination. A window will open through which you can additionally adjust the picture quality.

Select Projector Only or 2 Screen Only. Wait for the Windows operating system service to automatically select the optimal resolution.

In some situations, the suggested recommendations do not help. After selecting a video source and adjusting the resolution, the image is still too distorted. Black bars may appear on the sides of the screen or the picture may be cut off. In this case, you need to configure the video card.

As an example, consider the optimization of the basic parameters of an NVIDIA video card:

  • Click on an empty space on the desktop with the right mouse button. In the drop-down menu select the command “NVIDIA Control Panel”.
  • On the left there will be a list of special functions, click on the section “Change resolution”.
  • In the panel on the right, select the display, and in the lower menu, click on the “Settings” button. We select the command “Create custom permission”.
  • A window appears with detailed picture settings for the large screen, which is the TV.
  • At the top, change the number of pixels horizontally and vertically. Run a “Test” from time to time to check the correctness of the entered parameters. Continue until you find the optimal screen resolution.

For laptops with an ATI GPU, the setup instructions will be slightly different due to the different interfaces. However, the algorithm of actions itself is approximately the same.

There is a way to wirelessly synchronize a laptop with a TV using Intel WiDi technology. However, it is only suitable for owners of laptops with a Core i3 CPU or higher. These devices are equipped with a wireless TV connection system. Interaction will be correct only with the latest versions of TV equipment.

How to connect a laptop to a TV via HDMI

One instead of ten is the advantage of HDMI for transporting high definition video and audio signals. If some eight years ago, only TVs, players, game consoles with the SOURCE engine, media centers of the latest generation were equipped with such a connector, then today it has become a standard. Any modern multi-content playback device without HDMI looks like a museum exhibit, because since its introduction in 2003, this protocol for high-definition signal transmission, combining quality and space saving, has surpassed other standards.

Varieties of HDMI cable

To play computer content at the highest quality level, when the connection is due to certain requirements or restrictions, it is possible to use different types of HDMI cable:

  • Standard. It is the simplest type, it has a small bandwidth. For home devices, this type of cable is optimal, unless there are high demands on video and sound quality. These properties are significantly affected by the length of the cable, how well the plug is fixed, and which video card is installed on the PC.
  • Standard with Ethernet. This is an advanced cable type that provides two-way data transmission, provided both devices support Ethernet HDMI technology.
  • High Speed ​​is the type of cable that provides maximum resolution, bandwidth and versatility. With its help, it will be possible to connect absolutely any home devices.
  • High Speed ​​with Ethernet. high quality high speed cable with additional data transfer function using Ethernet HDMI technology.
  • Standard Automotive is a cord designed for use in vehicles. A significant difference between this type of cable from the previous ones is its resistance to vibration, since special connectors rigidly fix the connection. Even the latest type of HDMI cable is protected from sudden changes in temperature and exposure to high humidity.

How to connect a laptop to a TV

  • Make sure you have the correct connectors. To connect a laptop to a TV, each of them must have an appropriate connector, otherwise you will have to look for alternative connection options.
  • Connect the HDMI cable to the connectors of the laptop and TV, after disconnecting both devices from the power source. Insert the plug, turn on PC and large screen electronic device for further setting.
  • Set the correct signal source on the TV through the menu settings using the remote control and selecting the appropriate item that appears in the drop-down list as HDMI.
  • Customize your TV and laptop screens to find the best picture for you.
  • The hardware method involves simultaneously pressing the keys on the fn f4 laptop (on Lenovo, in others it is the button with the TV on the quick panel) and then choosing one of four options for connecting to the blue screen. To activate the appropriate mode, you just need to press the Enter key by selecting the desired item.
  • The software method of connecting two devices provides for setting through the laptop display and the desktop, where by pressing the right mouse button you need to find the line “Screen resolution”. Go to the “Multiple screens” section, and there select the optimal playback mode in the drop-down menu list.
  • Adjust the sound manually if you see an image when you connect, but no sound. On a laptop through the “Start” find the “Sound” tab, and then. “Playback”. In it, using the right mouse button, you need to find two lines: “Show disconnected devices” and “Show disconnected devices” in order to set a check mark next to each. Then turn off the PC speakers in the Speakers tab so that the audio signal travels through the cable to the TV. The sound will be heard there.

Advantage of connecting laptop to TV via HDMI cable

The indisputable advantage of this cable when connecting two devices is the high quality of the simultaneous transmission of video signal and sound, while other types of connection are inferior in characteristics. It is possible to connect a PC (Lenovo, ASUS) with any of the popular home devices. Philips, Sony Bravia, Toshiba. in two main ways: using a cable and wirelessly.

Watching any content on a large screen in comfort. simply by connecting a large plasma screen with a cord. You can make the signal clear without watching a video from YouTube. Attach the plug securely, provided the two devices to be connected have an HDMI jack. If at least one of them does not have such a port, you will have to use other connection standards:

  • Via a beveled rectangular VGA connector (found on the back of every device). With its help, it is easy to transfer the image, but not the sound to a regular (analog) TV, so you need an additional cable for the audio signal.
  • RCA input is available on all new TVs, but you will not be able to connect a laptop “through the tulip”, since this connector is a rare occurrence in them. But even if the PC has room for a yellow plug (composite video), then you will have to connect headphones to transmit the audio signal.
  • You can do without HDMI if you use a USB port and cable. The TV must be equipped with such a connector, and the laptop must be able to connect new equipment, otherwise video viewing will not be available. There is another option. connecting via a USB adapter, but for this you need to purchase the Q-Waves Wireless USB AV kit. It is connected to an electronic device with a large screen through the VGA or HDMI port, and the adapter itself is inserted into the PC. This device works with a limited range, so the TV and laptop should be near.
  • Without a cable, you can connect a laptop to a TV via WI-FI, if the latter supports this connection and is equipped with an adapter for wireless connection.

How to connect a laptop to a TV via HDMI

Installing the driver

It happens rarely, but if you installed the video adapter driver in manual mode and accidentally unchecked the HD Audio component, then this is why there is no sound on HDMI on the TV:

  • Open the device manager via control Panel or the main context menu (Win X) and go to the section of sound, game devices.
  • If there is only one component in the list (sound card), then the problem is really in the driver. But if there are several options, for example, NVIDIA HDA, then use the right-click menu to select the “Enable” command to enable the desired device:
  • Now I will tell you how to install the missing driver. First you need to go to the official website of the video adapter manufacturer and download the current version of the “firewood”.
  • After starting the installer, be sure to select the manual installation mode in order to control the process and see all the installed components. Pay attention to the mark next to “HD Audio Driver”. Let’s take an example from NVIDIA:

You must restart your computer for the changes to take effect. By the way, the Driver Booster utility, which I talked about earlier, will help to simplify the update procedure.

Changing the playback device

No sound when connecting a laptop via HDMI is a common phenomenon that can occur if the system does not automatically detect the connected device. You should check the audio settings in Windows:

  • Opening the control panel (via the Win X menu) and there we go to the “Sound” section, having previously selected the “Small icons” view mode. You can make it easier. right-click on the speaker image, which is located near the active language indicator in the notification area:
  • We select the item “Playback devices” and view the list of devices in a new window. If headphones / speakers are active, look for other items that contain “High Definition Audio” in the title or something like that. As soon as you find it, select the required component and click the “Default” button (or activate it through a similar item in the context menu):

Remember to save changes to achieve the desired effect. Well, it turned out?

But what if there was no required element in the list? Then let’s move on.

No sound through HDMI to the TV from the computer

Nowadays, almost every computer has a digital audio-video output, through which a signal can be transmitted to a large screen. But the next problem often arises. we connect the laptop. no sound through HDMI to the TV! An unpleasant situation when the image is visible, but the voice is not heard. Let’s try to figure it out and find a solution.

Checking volume levels

This is the very first thing to do. If everything worked yesterday, but today the indicated problem appeared, it is worth checking the volume on the TV and the controls in the operating system. Perhaps someone has screwed on the sound from the remote control or activated the “quiet” mode using the Mute button.

Simple ways

People often write to me: “I connect HDMI, and the sound comes from a laptop. What to do?” Now I will tell you a few methods that even beginners can handle. But first, I recommend the article about Honor. about the correct connection.

Nothing helps

  • If the laptop does not transmit audio over HDMI, and all the above steps were useless, I recommend taking another cable for testing. Or connect another PC to the TV. This way you can narrow the circle of “suspects”.
  • Sometimes you have to use adapters, which may also be faulty.
  • If additional software is installed to manage the adapter, try digging deeper into its settings:

Did you fix the issue “no sound on TV through HDMI cable”? Congratulations! Otherwise, I am waiting for your comments.

Setting up audio streaming from laptop to TV

Sometimes it is not necessary to specifically adjust the sound transmission from the laptop to the TV. The sound appears immediately after adjusting the video image. But if there is no sound, then you just need to set it up on a laptop. This is done as follows:

  • Click on the “Audio” icon with the mouse. This icon is depicted as a small speaker at the bottom right of the screen.
  • In the window of the drop-down menu, find the “Playback Devices” tab. Click on it.
  • In the window that opens, select your TV as the default audio output device.

All. Now turn on any video file on laptop and check the audio output. On TV, the video image must be accompanied by sound.

In addition to sound, there is also the possibility of additional settings for the image output to the TV.

Viruses on the computer

Sometimes the laptop does not see the TV via HDMI due to the presence of viruses or malware on the laptop. Such a problem occurs extremely rarely, but in no case can this cause be completely ruled out.

To increase the level of protection of your PC or laptop, download an antivirus. You don’t have to buy a license at all. The first time you can get by with the free version, the action of which is limited in time. on average about 30 days. As an example, consider the process of starting a scan using Kaspersky Anti-Virus:

  • Activate the program, and then start the scan command by clicking on the corresponding icon.
  • Select the type of scan. “Full scan”, and then click on the “Start scan” button.
  • A comprehensive scan of the operating system for viruses can take about 2-3 hours. If the antivirus finds malicious applications or infected files, this will be reported in the scan report.

Difficulties in the process of setting up a PC and TV connection via HDMI arise extremely rarely, but if problems appear, then they can be solved by our own efforts. An exception is broken ports. Replacing the HDMI interface or re-soldering the contact pad without professional equipment will not work.

TV not configured

Some TV models do not have an option to automatically detect the signal source. Especially if TV synchronization with other devices has been previously configured. In situations where, when connected via HDMI, the TV does not see a laptop or computer, take the remote control, and then select the list of available signal sources. From the proposed list, you need to select “HDMI”.

If the signal was not detected automatically when the cable was connected, then you need to do all the work manually. Step-by-step algorithm of actions:

  • One plug of the cable needs to be inserted into the port on the side or back of the TV. The second plug is inserted into the corresponding socket of the PC or laptop.
  • Take the remote control and press the “Source” or “Input” button. The name may vary depending on the model and manufacturer of the TV. When the list of available sources appears on the screen, select “HDMI”.
  • Go to TV settings to select a specific connector. TVs are predominantly equipped with two HDMI inputs. The connector number can be found directly below it. In the settings, select the one into which the cable was inserted. You can switch between ports using special buttons or numbers 8 and 2.
  • To make the changes made to the settings take effect, you need to press the “Enter” or “OK” button on the remote control. If there are no such buttons on the remote control, then just go down in the menu by pressing a little, and then select the “Apply” command. In the English version of the menu, it will be called “Apply”.

Remote controls for many modern TVs have an HDMI button. This means that you can ignore the second point of this instruction. Just press this key. As a result, it will switch to this signal source. Select the required port beforehand. How to do this is described in the third and fourth paragraphs of the instructions.

If you have any difficulties in the process of selecting a signal source, carefully study the instructions that came with your TV. It describes in detail the process of connecting additional devices using the HDMI connector.

Problem 1: No signal on the screen, no picture

So, you have connected the devices with an HDMI cable, but the image does not appear. In this situation, the following actions are possible:

  • The first step is to check the cable connection both on the TV panel and on the laptop itself. The cable plug must fully fit into the HDMI connector of both devices.
  • Next, check the settings of the TV and the laptop itself. The number of the connected HDMI port is indicated in the TV settings, and the image output method is indicated in the Windows Control Panel. The process of connecting a PC to a TV is described in detail in our other article at the link below. We advise you to follow all the recommendations from there and if the problem reappears, refer to this article again.

HDMI Audio Channel (ARC) audio support may not be supported by your device. Despite the fact that now almost all devices are equipped with ARC technology, the problem has not remained in the past. The fact is that as soon as the HDMI interface appeared, it was transferring only images. If you are “lucky” to purchase a device where HDMI of the first versions is installed, you will not be able to implement sound transmission in any scenario. In this case, you will need to replace equipment or purchase a special headset.

Don’t forget that a cable that doesn’t support audio output can also be the culprit. Check the specifications of your TV and laptop to see if the HDMI port works with sound. If there are no complaints about the connectors, you should try to replace the cable with a new one.

Computer cannot see TV via HDMI

Synchronization of the TV and computer allows you to significantly expand the functionality of the equipment. The user will be able to run video games on the big screen, watch movies, series and TV shows. There are several connection methods, but HDMI remains the priority option. In some situations, the computer cannot see the TV via HDMI. What is causing this problem? There are several options. Now we will consider each of them, as well as provide useful recommendations for reconnecting.

The main role of HDMI inputs

The emergence of new digital interfaces such as HDMI contributed to the obsolescence of the previously used popular VGA. He not only transmitted the image with a lower quality, but also distorted it, which often caused difficulties in work. The connection in question has a large bandwidth and supports audio transmission.

In addition to HDMI, several other types of digital data transmission interfaces are popular. DVI and DisplayPort. They all have different connectors and some characteristics, which allows you to use the required connection for different situations. Read more about comparing these interfaces in our articles on the links below.

HDMI connection in Winodows 10

We take a regular HDMI cable. We connect one end of the cable to the TV in the HDMI connector. There can be several of them, connect to any.

We connect the other end of the cable to a laptop or stationary computer.

If the picture from the computer does not appear on the TV, then most likely you need to select the signal source on the TV. The remote control must have a dedicated button. Usually, it is signed with INPUT, or SOURCES. Click on it, and as source, select the HDMI connector to which we connected the cable.

An image should appear on the TV.

In Windows 10, you can control the second screen. In our case, this is a TV. In the top ten this is called “Projection”. To call this menu, just press the WinP key combination. A menu will appear on the right in which you can choose one of 4 options.

For example, you can display the image only on the TV.

Connection instructions

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

  • Turn off your TV and laptop. This must be done so as not to damage the contacts as a result of a possible spark.
  • Connect the ends of the HDMI cable to the input and output connectors (TV and laptop, respectively).
  • Turn on both devices.

Most likely, you will not see the projection of the laptop screen on the TV.

  • Enter the TV Menu and find the Input List item. It can also be called up by pressing the “Input” key on the remote control.
  • In the list that appears, click on the input source: HDMI.
  • After that, the image from the computer should appear on the TV.

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

  • Press the WinP keys at the same time.
  • In the window that appears, select the type of projection.

The best way is the “Second Screen Only” option, in which the image from your machine will be accurately copied to the TV screen, while the computer display itself will remain off. Choosing a different connection will cause two monitors to work at the same time, which is distracting.

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

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

  • Right click on the desktop.
  • Select “Screen Options”.
  • In the window that appears, click “Advanced display options”.
  • Then click on “Detect” and after displaying the parameters of the external screen, select the maximum resolution from the drop-down list.

Advice! If you do not have cable TV, and IPTV hits your wallet hard, you can watch TV through a computer: turn on online broadcast or sopcast on PC and broadcast the image on TV.

Why is there no image on the TV from the computer (laptop) via HDMI cable

In some cases, after connecting the TV to a computer or laptop via an HDMI cable, the image simply does not appear on the TV. Rarely, but it also happens that there is sound via HDMI, but there is no picture on the TV. Although, it seems to me that most often they are faced with the reverse problem when there is an image, but there is no sound via HDMI.

In this article, we will try to deal exclusively with the problem of image output via HDMI cable. It seems that everything is simple there, we connected the TV to the computer, selected the desired input on the TV, and if necessary, then on the computer we also select the required image output mode. And according to the idea, everything should already work. And instead we see the inscription “No signal” on the TV.

Before moving on to any tips, check out the instructions for connecting your TV to your computer via HDMI:

If you do everything according to the instructions, but there is no result, and the image has not appeared on the TV, then now we will understand.

There is no signal on the TV via HDMI, and there is no picture

1 First of all, you need to check the cable connection, and remember the HDMI input number on the TV to which the cable is connected. Check if the cable is well plugged into the outlet on a laptop or desktop computer. Then, check the cable connection on the TV, and be sure to check which HDMI input you connected the cable to. They are signed. It looks like this:

For example, I connected the cable to the HDMI input under number 3. The fact is that the TV is likely to have several inputs. And in the settings we will need to select the one to which we connected the cable.

2 Checking the settings on the TV. We select the appropriate HDMI input in the settings. Not always, after connecting the cable, an image from the computer immediately appears on the TV. Most likely, you will see the inscription “No signal”, or “Cable not connected”. There should be a button on the remote control from your TV that opens a menu with a choice of signal sources. On Philips TVs, for example, this button is labeled SOURCES. Click on it, and from the list select the HDMI input with the desired number.

On LG TVs, this is the INPUT button. Click on it and select the required source. On the new LG TVs on Web OS, it may have already been done somehow differently. But, the scheme is always the same on any TV (Samsung, SONY, LG): open the menu with the choice of the signal source, and select the HDMI input with the desired number (to which the cable is connected).

3 Checking the settings on the computer. The computer may have turned off the output of the image to the projector (TV, monitor), so the picture does not appear on the TV and there is no signal. It’s very easy to check. In Windows 10, Windows 8 and Windows 10, just press the WinP key combination and select one of three options for displaying the image: Duplicate, Extend, Projector only.

If you have selected “Disconnect projector”, then HDMI image will not be output. In Windows 10, everything is about the same, only there a menu on the side of the screen appears.

4 If you still did not manage to make friends between the computer and the TV, then it would be good to find out what the reason is: in the TV, in the computer, or in the cable. This is not difficult to do. Especially if you have another PC, TV, monitor with HDMI input, or one more cable.

Try connecting your laptop to another TV or monitor, for example. If everything works, then the problem is in your TV (which is unlikely). This will eliminate cable problems. Also, you can just take another laptop (even borrow from a neighbor) and connect it to a TV that does not display an image. If everything works, then the problem is in your laptop (computer). What happens most often.

5 One more tip. Try updating the video card driver with your HDMI-connected TV. Just download the driver from the laptop / video card manufacturer’s website and install it.

Problem 2: sound is not transmitted

HDMI integrates ARC technology, which allows audio to be transmitted along with video content to a TV or monitor. Unfortunately, the sound does not always start to be transmitted immediately, since to connect it, you need to make some settings in the operating system, update the sound card drivers.

In the first versions of HDMI, there was no built-in support for ARC technology, so if you have an outdated cable and / or connector, then to connect the sound you will either have to replace the ports / cables or buy a special headset. Audio support was first added in HDMI version 1.2. And cables manufactured before 2010 have problems with sound reproduction, that is, it may be broadcast, but its quality leaves much to be desired.

Lesson: How to connect audio on TV via HDMI

Problems with connecting a laptop to another device via HDMI are common, but many are easy to fix. If they cannot be solved, then most likely it will be necessary to change or repair ports and / or cables, since there is a high risk that they are damaged.

We are glad that we were able to help you solve the problem.

If the sound on the TV does not work when connected to Windows 10 via HDMI

Perhaps, after connecting the TV to the computer, the sound will not play from the TV speakers, but from the laptop speakers, or the connected speakers. This can be easily fixed.

READ  How to connect your TV to your home internet

Right-click on the volume control icon in the notification bar and select Playback Devices.

Your TV should be on the list. Right-click on it and select Set as default.

Sound will now be heard from your TV speakers.

The laptop sees the connection, but there is no corresponding picture on the TV display

First, check the reliability of the connection, the HDMI cable should not hang out in the socket of the TV or laptop. Then carefully inspect the HDMI wire, if you find kinks or damage, think about replacing the wire, perhaps this way you will solve the problem.

If the wire is okay, then make sure you select the correct jack when connecting to your TV. The fact is that some TV models have several HDMI ports, and by default, the settings set to receive a signal from only one of them.

Video card problem

Damage to the GPU is a common cause of problems in computer image projection. If you see a No Signal error on the screen, try updating your drivers. You can download the software package through the manufacturer’s official website. And you can also use the standard Windows tools, acting on this principle:

  • Open the “Control Panel”.
  • Choose “Device Manager”.
  • Go to the “Video adapters” section and find the item “Update drivers”.
  • The system will offer 2 update options: via the Internet or root storage.
  • The installation process runs in the background.

Inoperative connection port

All interfaces and connectors often fail due to mechanical breakdowns or contact closure. It is known that careless operation of equipment or power surges cause problems with displaying images on an external monitor. At the same time, experts recommend connecting only if the equipment is disconnected from the mains.

The HDMI connector will wear out and oxidize during use. Therefore, the technician cannot determine the connection. And to eliminate the error, you should use professional help and transfer the HDMI connector for soldering.

Incorrect monitor settings

If the connector is correctly selected and the cable is fully functional, try checking the settings on your PC or portable device. Display errors are often caused by inappropriate system parameters. To check the settings, follow the following procedure:

  • Select a free space on the desktop with the mouse cursor and press the right key.
  • In the section that opens, select the item “Screen resolution” or “Graphic characteristics”.
  • Determine the data transfer method on the external monitor and set the appropriate resolution.

Enabling the demo settings on a laptop is much easier. To do this, just hold down the Fn F4 combination, after which the system will automatically determine the resolution.

Features of HDMI wires

The HDMI interface is actively used in modern technology for the simultaneous transmission of audio and video files. It lets you stream content in Full HD or 4K resolution without worrying about delays or crashes.

The first prototypes of the connector were developed back in 2002. After that, manufacturers have modernized them in various ways. And thus they increased bandwidth and transmission quality. In addition, HDMI now supports various formats and other interesting features.

Version 1.4 and higher can be used for network signal transmission. As well as 3D videos or files in 4K resolution. And unlike wireless technologies, HDMI provides high speed, reliable and stable internet connections.

The following connector form factors are common today:

  • Classic performance. type A.
  • Mini HDMI. type C.
  • Micro HDMI. type D.

The latest varieties are suitable for smartphones, photographic equipment and other portable gadgets.

TV not configured

Before you start repairing your HDMI cable, you should check your TV settings. Indeed, some devices do not have an automatic transmission source selection function. And especially if you have chosen other parameters before. Therefore, first of all try to change the settings using the remote control and change the sources by selecting “HDMI” from the list.

To fix the error, follow this sequence of actions:
