I'm primarily using my PS3 for BD playback on my HDTV with 720P native resolution. Right now I have 480P, 720P and 1080i resolution checked and the PS3 defaults to 1080i.
Based on some of my readings on the forums, 720P would be a better resolution so I'm thinking of changing it (uncheking 1080i). Is that a good idea? What resolution do you have yours at? What impact do you forsee if I play games in the future with max res @720P?
