Computer connection via HDMI cable is possible if the computer's video card is able to produce an HDMI signal and is equipped with an HDMI output terminal.
There are adaptors and computer components available on the market that will allow you to connect a PC to most televisions.
If you have a Media Center PC that has standard video component connections, you can connect directly to the television.
Once the PC is connected to one of the video inputs at the back of the television select the input through the input list.
