How to Connect a PC to an RGB TV

By James Clark

An RGB TV receives video signals from a component cable that breaks down the video signal into three parts. Each part of the signal is transmitted through the red, green and blue color-coded cables that match the colors on the three TV input jacks. This type of connection can be converted with an adapter cable to work with the video port found on many computers and laptops. The 15-pin Video Graphics Array (VGA) cable that connects to the computer can be attached with standard plugs on the other end to the RGB TV.

Things You'll Need

  • VGA to RGB cable

Step 1

Insert the red, green and blue plugs on one end of the cable into the matching color video input jacks on the back of the TV.

Step 2

Connect the VGA plug on the other end of the cable to the matching video port on the computer. Line up the plug so the three rows of metal pins inside will fit within the corresponding holes in the computer port.

Step 3

Turn the two locking bolts on the VGA plug clockwise so the cable cannot come off the computer.

Tips & Warnings

  • Turn off the TV and computer while connecting the video cable.
