Okay. So I freely admit to being an HD newbie. We got a widescreen HD-TV, rear projection, for Christmas. I'm trying to test out my X-Box 360 with the HD component cables, but 1080p and 720p both fail to work right. My options are 1080i and 480p. I was wondering if someone who knows a bit more about these resolutions knows which would be better for basic gaming display.
