Axiom Home Page Forums General Discussion Technical Questions Anybody have their computer connected to their tv?

I have a Radeon X300 series.

My current setting is 1024 x 768. I don't have the option go go xxxx x 1080, the closest I have is 1280 x 1024. I do have a 1280 x 720, does that mean it outputs 720p? That doesn't help me since my tv is 1080i right?
