If you're looking for a cheap LCD that supports up to 720p and 1080i, you could do worse than this Olevia. It's 42-inches of pure low-end goodness, and takes in HDMI, composite, component, and VGA. The Olevia won't win any awards for picture quality, but at least you've got enough cash left over to actually buy stuff that you can watch on this thing.
