I've always read that LCD's look best when shown in there native resolution. And that any scaling degrades clarity. So if your source is a 720p or 1080i HD signal, wouldn't that look best on a LCD or Plasma TV that has a native resolution of either 1280x720 or 1920x1080? Then why is it that all of the larger Plasma's and LCD's TV's have funny native resolutions like 1366x768 or 1280x768? Doesn't this mean when they are displaying a HD signal of 720p, it's getting scaled up to 768 and losing clarity? Furthermore, these native resolutions of 1366x768 or 1280x768 are not even 16:9 ratios. What am I missing here?
