How to output an image from a computer to a TV using an HDMI connector
This type of connection between a computer and a TV is the simplest and most common in modern devices. In order to get a picture, you need to have an HDMI cable and the corresponding connectors (they have the same appearance) in the TV and computer. Before connecting, both devices must be disconnected from the network (ports or the entire connected device may burn out).
Tip. If the TV is hanging on the wall or it is not possible to connect the cable conveniently, then use special cables whose plug is at an angle of 90 degrees (or there are special removable corners).
When connecting, be sure to disconnect the monitor. In principle, after connecting the cable, an image should immediately appear. In some cases, you need to adjust the settings.
Required HDMI Settings
Consider how to display the image on the TV and what is needed for this. To do this , select the required screen resolution (when connected, parameters are set automatically, they may not be suitable for some types of work).
You can select the appropriate option in the “Screen Resolution” menu. Try several options, select the one you need. Remember that a higher resolution implies a clearer picture, but reduces everything on the screen.
Now go to the “Advanced Settings” tab and select “Monitor”. Set the frequency to 60 Hz or more.
What needs to be done to make sound
After solving the question of how to output the image from the computer to the TV, you need to decide on the sound. First, check for an audio output driver through HDMI. This is checked in the “Device Manager” menu. You need to go there, open the “Sound, game and video devices” section and check if there is a device with support for High Definition Audio.
Then go to the “Sound” tab in the control panel and make sure that you have a digital audio device (HDMI).
You should also be aware that different TVs may have HDMI inputs that do not accept sound. It accurately receives the sound of HDMI 1. If there is still no sound, then you should look at the instructions for the TV, there may be other recommendations.
If you correctly followed the above instructions, an image should appear on the TV screen. But it may be that the resolution of the TV will be incorrectly determined or unused black bars will appear on the screen. Then you need to run the function "Display Settings" and change the extension to the desired value.
