Video is setup using the Overscan and Color 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). Overscan adjustment 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 is usually the
correct choice for most video inputs.
Presets
Up to 30 presets may be stored for future retrieval.
Input 1 & Input 2
The “Video Setup” window has controls for adjusting peak, boost, skew (QM Input
#1 only) and presets for each of the inputs as shown in the following illustration.
Changes are made in real time.
“Video Setup” Window - Input 1 Tab – QM Version
The Auto button can be used to auto detect video when a single video source (per
input) is connected.
Adjust Peak and Boost to compensate for white or black streaking. On Input #1 of
QM versions, adjustments for red, green and blue skew are available to compensate
for the varying distances that a video signal must travel in a QM cable.
NOTE: QM Input #2 on the TPMC-15/17-QM-L does not have adjustments for
skew compensation.
