Like a lot of people I'm a bit confused about HDTV. I'm looking at buying either an LCD or rear-projection TV later in the year but I can't get my head around resolutions. I'm looking at using it mostly for HD-DVD and xbox360 but can't figure out whether a native 720p or 1080i resolution would be optimal. From what I've read here, the LCDs have to display at their native resolution, so if they're 720p, then a 1080i signal has to be downscaled to that. If I had a 1080i native resolution, then a 720p signal has to be upscaled to 1080i. Am I correct in thinking that upscaling may show larger pixels or artifacts, but that downscaling might lose detail? I think 720p seems to be the signal I would be using most, but for films I would like to try 1080i. If I had a 720p screen would that basically mean that I'm not really seeing the extra detail from 1080i as it's being downscaled? Am I imagining upscaling to be worse than it is? I can't quite grok it.
