What do I need to get dual video output from my PC?

[b14desman]

Hi, please help answer a basic question. I'm planning a new build and would like to be able to
connect my PC to the TV and play video's from the PC on both PC monitor and TV at the same time?
How do I do this?
Thanks
Colin

You need a graphics card that has TV output (you'll be hard pressed to find one that doesn't), and then set it to "clone" mode.

Note that some things don't clone, like video overlays and certain kinds of 3D renders. For video however, there are special modes of operation (like ATI's "Theater Mode"), wherein the video plays on the main screen as it normally does, and at the same time is shown fullscreen on the TV-out.

You could also go with 2 seperate physical cards, which would make all the overlay issues go away.
