Video is setup using the Color and Overscan controls. The following test patterns are
recommended for adjustment.
Overscan
Overscan is the active image area in a video picture that is outside the edges of the
display device (does not apply to RGB). Over-scan first came about because of noise
and other artifacts at the beginning and end of the scan lines. To reliably eliminate
the noise and fill the screen with a picture, the outside edge of the active picture area
was pushed out past the edge of the display area. The average or targeted over-scan
loss is about 5 to 10% of the image on each edge. Digital images have nearly
eliminated the noise and other artifacts at the edge of the picture, so more of the
video image can be safely shown. The Normal setting will usually the correct choice
for most video inputs.
