Black bands appear at the top
and bottom of the screen.
❑ 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).
❑ Programs in 4:3 aspect ratio will have bands on left and right sides of the
screen. To select full size see page 36.
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.
