The RGB PC input on Vizio TVs is typically used to connect computers to a Vizio TV, but you can also use it to connect and display any device with an RGB or VGA output. After connecting the device to a Vizio TV, you can display the device on the screen by selecting the appropriate input. If the device you are connecting to the Vizio TV also has an RGB or VGA audio output, you can transfer audio from the device to your Vizio TV using a cable that also supports the transfer of RGB audio.
Step 1
Connect one end of the RGB cable, also known as a VGA cable, into the RGB PC input in the lower-right corner on the back of your Vizio TV. Screw in the holding pins on each side of the connector. If the device you are connecting to the Vizio TV also has an RGB audio output, plug the audio input cable extending from the RGB connector into the small audio input slot directly to the right of where you connected the RGB cable.

Screw in the holding pins on each side of the connector. If there is an RGB or VGA audio output next to the RGB or VGA input, plug the RGB audio cable extending from the RGB connector into the slot.
Step 3
Press the "Power" button either on your remote or on the right edge of the TV to turn on your Vizio TV.
