The compression used by certain digital broadcasts and DVDs may cause your
TVís 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 TVís large screen
and ability to show very fine detail, and is normal for certain digitally recorded
programs. Adjust the reality/clarity in the
TVís screen to display less detail than usual, or cause artifacts (small blocks or
