Quick question : Ideally , would you want your display to be either 1280x720 or 1920x1080 (or as very close to either as possible) so that no scaling would have to be done at all ? (other than having 720p upconverted to 1080i if display is 1920x1080 or 1080i being downconverted to 720p if display is 1280x720) A lot of displays have non-standard resolutions that are in between 1280x720 and 1920x1080. Why is that and why aren't they EXACTLY 1280x720 or 1920x1080 ? Which displays out there have exactly one of these resolutions ? What I'm really trying to figure out is scaling something that should avoided as much as possible or is it always necessary to at least some small extent ?
