DVD resolution on Widescreen TV's with full 720 x 480 playback
Viewing angle, left to right, at the distance of maximum sharpness for DVD playback is 14 degrees for all screen sizes. If you view a standard DVD at this distance / angle you will be at the limit of an average person's eyesight so it would be difficult to tell if the playback is a standard DVD or a better, blu-ray DVD. Moving closer, you should begin to see individual pixels. If you are closer than this distance it should be easy to see the that blu-ray resolution is better.
