Since HDMI is all digital there should be nothing to configure in xorg, it "just 
works".

There is an overscan issue which can usually be resolved by digging through your 
TV setup menus. It might be called something like "PC Game Mode".

If your TV has more than one HDMI input you might try all of them. One of our 
TVs had different options for some of the inputs (ie "Game Mode"/"PC mode"/Exact 
Scaling"/whatever) was only available on HDMI2.
