Some wide screen programs are filmed in aspect ratios that are greater than 16:9
(this is especially common with theatrical releases). Your TV will show these
programs with black bands at the top and bottom of the screen. For more details,
check the documentation that came with your DVD (or contact your program
provider).
Certain programs on DVD or other
digital sources display a loss of
detail, especially during fast-motion
or dark scenes.
❑
The compression used by certain digital broadcasts and DVDs may cause your
TV’s screen to display less detail than usual, or cause artifacts (small blocks or
dots, pixelations) to appear on your screen. This is due to your TV’s large screen
and ability to show very fine detail, and is normal for certain digitally recorded
programs.
