HDMI Setup. How to do it?
The HDMI output (High-Definition Multimedia Interface) is required to transmit a high quality digital signal. It is used to broadcast video and sound. In this article we will explain how to set up HDMI.
First of all, it should be said that all modern video cards for personal computers are equipped with this output, besides, HDMI can be found on laptops, even on those models that use the integrated video card.
For a start, it is recommended to explore the capabilities of your video adapter. If your video card does not have HDMI output, you can use the DVI channel using a special adapter, which is also called the DVI-HDMI connector. A feature of such adapters is the ability to transmit audio.
In order to configure HDMI, you will need to study the technical characteristics of the TV to which you are connecting. Be sure to ensure that its HDMI input is designed to receive a sound signal. All you need to connect is an HDMI-HDMI cable, one end of which is inserted into the video card of the computer, and the other end into the TV connector.
If you want the TV and monitor to work simultaneously, you need to set the synchronous operation option of these devices. To do this, open the “Start” menu and enter the “Control Panel”. Next you need to select “Screen” and click on the item “Screen Resolution Settings”.
In the dialog box that appears, you must activate the function “Duplicate screen”. Now the computer will transfer the same image to all devices. If you need both displays to work independently of each other, you should activate the “Expand screen” mode. In this case, you will need to pre-assign the display of the computer as the main device.
To set up HDMI, you also need to adjust the audio transmission. To do this, open the “Control Panel” and select the item “Equipment and Sound”. Next, you need to click on “Sound Device Management”. A dialog box will appear on the screen in which you should go to the tab “Control Sound Devices”. Here you need to mark the equipment HDMI Output, clicking on its icon with the left mouse button, and then click on the “Default” button.
Next, you need to click on the “Apply” button and close the dialog box. Now, as a test, you can run some video and make sure that the HDMI output works correctly. It should be noted 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 you don’t need any special knowledge to do this. Finally, it is worth telling how to choose the right HDMI cable.
Such cables are of two types: to support high resolution, and also 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, the greater the likelihood of signal loss. Therefore, some manufacturers offer so-called active HDMI cables that 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.
