commercial content. When HD content channels switch to SD contents (commercials), the picture size will reduce
and will be surrounded by a black border.
Black bands appear at the edges of
the screen Some wide screen programs are filmed in aspect ratios that are greater than 16:9 (particularly for theatrical
releases). When displaying these programs, black bands will appear at the top and bottom of the screen .

scenes with fast motion or a darker
tone
This is because the digital compression of the source content used by certain digital broadcasts and DVDs may
cause your TV screen to display fewer details than usual or artifacts (small blocks or dots, pixilation) on the
screen. These signal compressions are more visible and depend on the clarity and resolution of the television.
