HDMI output (High-Definition Multimedia Interface) is needed to transmit the highest quality digital signal. It is used for video and audio broadcasting. So, HDMI, how to set it up? First, a little preface. It must be said that almost all personal computers are equipped with video cards with an output such as HDMI, in addition, HDMI is quite common even on those laptop models that use a standard integrated video card. Let's, for starters, we will try to explore the capabilities of your video adapter. In the event that your video card does not have an HDMI output, you can use the DVI or VGA channel using a special adapter, which is also called a DVI-HDMI connector. A feature of such adapters is the ability to transmit an audio signal.
How to set up a TV via HDMI? To set up HDMI, you will need instructions from the TV to which the connection will be made, where the technical specifications will be written. Be sure to make sure that the HDMI input is designed to receive audio. To connect to a TV, you only need an HDMI-HDMI cable, one end of which must be inserted into the computer's video card, and the other will need to be inserted into the TV's connector. If you want the monitor and TV to work at the same time, you will need to enable such a function as the synchronous operation of these devices.
Synchronous operation of devices
To do this, you will need to open the "Start" menu and go to the "Control Panel" (you can go there in any way convenient for you). Next, you will need to select "Screen" and go to the "Screen resolution settings" item. In the dialog box that appears, you will need to activate a feature such as "Duplicate Screen". From now on, the computer will transmit the same image to all devices connected to the video card. If you have a need for both displays to start working separately from each other, you will need to activate the "Expand Screen" mode. In this case, you will need to first assign the display as the main device of the computer.
How to set up sound via HDMI? To set up HDMI, you will need to adjust the audio signal transmission. To perform this action, open the "Control Panel" and click on the "Hardware and Sound" item. Then you need to select "Manage audio devices". A dialog box will appear on the screen, in which you will need the "Manage sound devices" tab. Well, here you need "HDMI Output". Click on its icon with the left mouse button, set "Default".
Now you need to click on the "Apply" button and close the dialog box with "sound devices". Next, as a test, you will need to run some video and make sure that the HDMI output and cable are working properly. It is worth noting that if you unplug the hdmi cable, then the standard audio port will turn on automatically. How to set up an HDMI cable? As you can see, the HDMI output is quite easy to set up and you don't need any special knowledge to do it. I almost forgot to tell you about which HDMI cable is better and which one should be chosen for further long everyday use.
Types of cables
There are two types of HDMI cables: high definition and HDTV. It is also worth touching on the topic of the length of the wires and take into account in advance that the length can vary from 1 to 10 meters; but do not forget that the longer the cable, the more likely it is that there will be signal loss. As a result, some manufacturers have sprung up to offer so-called "active" HDMI cables with various technologies that can be used to transfer data over very long distances. When you buy a cable, be sure to point yours to the wire as well as its connectors.
Connecting a computer or laptop to a TV can occur in different ways:
- VGA or D-Sud cable. Almost all monitors, PCs and TVs have such a connector. This is an analog connection that will not convey all the nuances of video files in the best way.
- DVI. A more modern version. Can work with analog and digital devices. Has its own subclasses.
- S video. In addition to it, you will have to purchase an adapter.
- RCA or tulips. Connecting a laptop and a TV in this way is rare.
- scart. A popular way, since such a connector is in modern TV models.
- HDMI cable. A good option for connecting a computer.
Common Causes of Connection Failure
If the TV does not see the laptop, and the connection is made, then the reasons may be as follows:
- The cable is connected incorrectly or is defective.
- Monitor settings error.
- Incorrect operation of the video card of a laptop or PC.
- The settings on the TV itself or any other brand are not configured.
Let's take a closer look at why the TV does not see HDMI and the second device through it.
Stages of equipment check
- First of all, you need to check the quality of the wire connection and the condition of the connectors.
- Next, you need to check the correctness of the computer settings.
- It then checks for driver updates and graphics card settings.
- Run an antivirus program to scan for malware.
- Port check. It is recommended that you connect to another device.
Cable check
If the TV connected to the PC suddenly stopped working, and up to this point everything was set up properly, it means that the cable has come off or it has been interrupted. The first option is more common, as you can hook the adapter just by passing by. But the second one is less common, since the optimal length of the HDMI cable is not so long as to lie on the floor and fall under someone's heavy leg.
TV settings
When the TV does not see the laptop via HDMI immediately after connecting the equipment, it is most likely that the signal source selection on the TV itself is incorrect.
If there is no signal from the computer, then on the TV remote control you should find the “input”, “source” or “Imput” button, it may be immediately written “HDMI” on the TV from LG. Go to the window that opens and there, in the list of active inputs, select the one you need. Confirm the action by clicking on "OK".
If the equipment still does not connect after the performed operations, we carry out diagnostics further.
Monitor settings
After making sure that the signal from the TV is on the right path, we proceed to the diagnostics of the laptop or PC screen, or rather, to the settings. Any user with basic knowledge of their computer can conduct them:
- Move the mouse over any free space on the screen and press the right button.
- In the list that appears, select "Screen resolution" or "Graphic characteristics" depending on the type of OS.
- Select the appropriate option for displaying the picture on TV. Permissible permission is written in the device passport, stick to it.
Everything is easier to do on a laptop. Hold down the "Fm" and F4 buttons at the same time, hold until the best option is selected. After that, the laptop will connect to the TV correctly and the error that there is no image will go away.
Video card error
Another reason why the device connection does not work is the incorrect functioning of the PC video card. In this case, the laptop does not see another device or does not display an image on it.
To eliminate it, you need to try to install new drivers that are on the global network for each device model. Sometimes it may be necessary to completely reinstall or replace an item.
The number of pixels on a TV, whether it's LCD or plasma, is fixed. It depends on which company released it, on the diagonal of the screen, and the generation of the lineup. But, today, LG TV, capable of transmitting a picture with hdmi resolution of 1366x768 using the LCD panel of the screen, has to work in 720x576 pixels mode. This is because it is the standard for a conventional television signal. But an expensive TV model from Samsung and LG easily works in a mode that not every monitor has - 1920x1080 pixels.
It is logical that through a cable that allows you to connect to a high-quality hdmi signal source like a netbook or laptop to your LG TV, you can get a better picture. After all, passing through modern processors, which are equipped with PCs, the video signal is significantly improved. In addition, special programs have been created for the PC that allow you to use the LCD screens of expensive TV models to the limit of their capabilities. At the same time, a high-quality hdmi cable does not affect the picture quality of LG TV receivers.
Advantages of connecting TV equipment to a computer
Samsung's large LCD panels are great for broadcasting an HD movie through them. The diagonal size of the TV in hdmi mode allows you to see many details that are invisible on the monitor screen. Fans of LG technology, who use Internet capabilities instead of a relay network using a netbook or laptop, will understand me. The LCD screens of these types of PCs have a small diagonal. At the same time, this LG technique is able to give a high-quality digital signal. And although a large monitor extension can convey all the nuances of the picture, its size makes it impossible to comfortably watch movies.
Previously, for any laptop, the rule "it is only for work" was applicable. Today it is a full-fledged PC with all the advantages of this category of technology. And for this reason, a netbook, as well as a laptop today, has hdmi connectors that allow them to be connected through a special cable to a modern TV, it doesn’t matter if it’s LG, Rainford or Samsung - the main thing is that they also have an hdmi connector.
PC hard drive - like a TV tower for a TV
Connecting a TV to a personal computer is beneficial not only with a high-quality picture on the LCD panel of the satellite. Samsung is a well-known manufacturer of high quality hard drives. Any of them through the hdmi connector, using a special cable and appropriate programs on a PC, can be turned into a signal source for the latest generation TV from LG. And instead of watching a 720x576 movie through a large Samsung LCD panel, or using the same LG monitor with a resolution of 1366x768 but with a small diagonal LG LCD screen, you can combine the best of both options.
Even with the help of a netbook, you can watch high-definition Internet TV through any TV model with an HDMI connector and a connecting cable. This is also possible with a laptop and any stationary PC. After connecting a modern TV to a personal computer, you can independently manage the information flow that comes through communication networks.
We connect your TV to LG computer equipment
To connect your own TV to any PC variant, from a laptop to a stationary system unit manufactured by LG and other companies, you need to:
- The presence of hdmi connectors both on a laptop or video card of a PC-station, and on your TV.
- Cable with two hdmi connectors through which devices are connected.
- Some TV models only have a DVI connector. Then you can use special hdmi-DVI adapters to connect to a computer. In both cases, the signal to the LG LCD panel is transmitted in the same way. The main difference is that the DVI cable is capable of transmitting an analog signal through itself.
- The use of special software is recommended. It is designed to provide full functional use of a flat LCD TV instead of a standard monitor.
Using your PC as a TV source with a high fidelity HDMI connection is not only about seeing old movies in "new color". It is also a way to open all the possibilities of LG screens laid down by the creators.
Setting up an additional monitor for a laptop
Having used a special cable to connect your PC and TV through it, some people forget to switch to the correct input. And instead of pressing one button on the TV remote, they call the LG service center, complaining that hdmi does not work on the model. Or they start changing the settings on the computer, pulling the cable. And from such actions after a while it really breaks down.
LG remotes have a dedicated button to switch the TV to accept an HDMI signal from a connected PC and turn it into a larger version of a monitor. Press the button, then select the connector to which the cable is connected. Everything, the picture from the laptop should appear on the screen of your LCD panel in a second. And instead of small, albeit very clear pictures visible on the monitor screen, we can see all the small nuances on the large diagonal of the LG LCD panel. Further control of the video stream is performed using a laptop or other PC version, the connection of which is possible via a high-definition hdmi connector.
Duplicate laptop LCD screen is not always convenient
It is not always convenient to connect a separate LCD screen that duplicates PC information. Therefore, the use of an additional LG LCD panel with a laptop is possible as another desktop. To do this, after connecting your PC using the Windows Mobility Center settings, select the "Extend" option.
The external LCD now uses an HDMI cable and connection as a means to add an extra screen to the computer. At the same time, the PC is easily able to support the broadcast of the movie in hdmi-quality via cable, and the user can simultaneously give the computer parallel tasks on the second video panel. You can also set the following operating modes through the mobility center:
- "Computer only." Although a cable is used to connect equipment via hdmi connectors, in this mode the picture is only on the PC LCD screen.
- "Duplicate". Information from the PC screen is duplicated on the LG panel one to one.
- "Expand". The user himself asks the computer what and which of the LCD screens is currently broadcasting.
- "Only a projector." Through the connecting cable, the picture is sent only to the connected LCD panel. The PC screen is inactive.
For extended use of LG LCD flat screens, the Projector Only mode is recommended. For work, it is optimal to work together with a PC and an additional screen via an hdmi connection and the "Expand" option. But in fact, each person decides for himself the question of his own comfort.
If you are about to purchase or have already purchased an HD TV, then 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 it is necessary to familiarize yourself with some of its nuances beforehand.
Brief specifications of the HDMI cable
Before connecting an HDMI cable to a TV, it is important to understand their main characteristics. HDMI is a high definition multimedia interface. There are two types of HDMI cables: HDMI Standard and HDMI High Speed. Using HDMI Standard cables, TV receivers of all categories are connected: cable, terrestrial, satellite, including 3D, as well as ordinary non-(3D) Blue-Ray players and most HD video cameras. Cables of this category may have different markings, except for High Speed. Game consoles, computers, Blue-Ray 3D players. Game consoles, computers, Blue-Ray 3D players are advisable, but not necessary, to be connected with a High Speed cable.
One of the main subtleties of 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 kinked. Before purchasing a cable, you need to decide what connectors are on your device. Relatively old models of TVs and other equipment usually have two types of connectors - RCA (otherwise called "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 connect the most efficient connection, you need to purchase a cable, which - on the one hand - has a connector on the device panel, and on the other hand - HDMI. Finding such a cable is quite problematic, and if this fails, you need to use adapters that can have two or more connectors of various types.
How to connect HDMI cable to TV
How to connect HDMI cable to TV? The TV must be turned off before connecting the cable. If the TV device has S-video, then the cable is connected with the S-video connector to the TV, and HDMI to the computer.
It is undesirable to connect an HDMI TV to the DVI connector of a computer. Such a connection will result in a significant reduction in picture and audio quality.
After connecting the TV and the computer with an HDMI cable, the TV turns on first, and then the computer. When the operating system is loaded on the computer, the TV screen flashes, indicating that it is connected to an external source. The TV must be switched to AVI mode, in which the signal to it will come not from an external antenna, but from a computer.
How to connect the HDMI cable to the TV if the TV is connected to the computer with the 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 the instructions, following which you will get the image of the computer on the TV. In Windows 7, you need to go to the desktop in "Permission" - "Find". The TV device will be detected in the system and it will remain to mark it as the main monitor. If the TV is not detected, then you need to enter the properties of the video card again and repeat all the steps again.
In the properties of the video card, it is possible to adjust the resolution, desktop size, adjust the color and other settings.
If you experience image problems, it can be caused by both the HDMI cable and problems in the connected devices, which is most often caused by a software error.
The HDMI (High-Definition Multimedia Interface) output is required for high quality digital signal transmission. It is used to broadcast video and sound. In this article, we will tell how to set up hdmi.
First of all, it must be said that all modern video cards for personal computers are equipped with this output In addition, HDMI can be found on laptops, even on those models that use an integrated video card.
It is recommended to start explore the capabilities of your video adapter. If your video card does not have an HDMI output, you can use the DVI channel using a special adapter, which is also called DVI-HDMI connector. A feature of such adapters is the ability to transmit an audio signal.

A dialog box will appear on the screen, in which you should go to the tab "Sound Device Management". Equipment to be noted here HDMI Output by clicking on its icon with the left mouse button, and then clicking on the button "Default".
Next, click on the button "Apply" and close the dialog box. Now, as a test, you can run some video and make sure that the HDMI output is working correctly. It is worth noting that when the cable is disconnected from the port, the standard audio port will turn on automatically.
As you can see, setting up the HDMI output is quite simple and does not require any special knowledge. Finally, it is worth talking about how to choose the right HDMI cable.
These cables are of two types: to support high definition as well as to support HDTV resolution. As for the length of the wires, it can vary from 1 to 10 meters. However, it should be remembered that the longer the cable length, the greater the likelihood of signal loss. Therefore, some manufacturers offer so-called active HDMI cables which use various technologies to transmit data over long distances. When buying a cable, be sure to pay attention not only to the quality of the wire, but also to the connectors.
