Ok. So here's the situation. I'm thinking of buying an X2VGA 2 to run my xbox on my 20" LCD at HDTV resolutions. I currently use it with XBMC mainly as a media center. So my question is about this: Once you hook the original XBOX to an HDTV or a device that converts HD signals to VGA, how do you choose between the HD resolutions (480p, 720p, 1080i, 1080p)? Do the games automatically choose the highest resolution they can support? do you have to move into the original xbox dashboard to set the resolutions? can XBMC detect the availability of a HD capable display automatically? School me people.
