How to connect a computer to an old-fashioned desktop TV?
You can use the VGA interface of the old TV to connect the VGA interface of the computer. The connection method is as follows:

1. First, prepare a VGA cable to synchronize the screen display on the computer with the TCL LCD TV.

2. Find the VGA socket on the computer and connect one end of the VGA cable to the VGA socket on the computer.

3. Find the VGA socket on the TV and connect the other end of the VGA cable to the TV.

4. Turn on the TV and press the "signal source" button on the TV remote control.

5. The TV will display the menu of "signal source", select "VGA" from it with the remote controller and press the "ok" key to confirm, and enter the VGA video synchronization mode of the TV.

6. After the TV is switched to VGA mode, you can connect the computer and display the screen of the computer.

? In order to get a better display effect, it is suggested to adjust the resolution of the computer according to the size of the TV. Generally, a 32-inch TV can adjust the resolution of the computer to 1280*720 pixels.

? In addition, because the VGA cable can only transmit video signals, but not sound signals, it can be connected to a computer to play sound and increase sound effects.
