Adjustments
The AV200R and AV201R receivers both include brightness and sharpness
adjustment dials. Additionally, the AV201R receiver is also equipped with two
extra dials to eliminate the effects of colour skew within the video image.
Brightness and sharpness adjustments
The brightness and sharpness adjustments
provided on every AV receiver allow you to
compensate for any losses incurred within
long cable links.
When making adjustments it is necessary
to have access to the AV receiver and to be
able to view one or both connected display
screens. Both adjustments, sharpness in
particular, are made easier when viewing high
contrast images with vertical edges, such as
black lines on a white background.
NOTE: Both video outputs are equally
affected by your brightness and/or sharpness
adjustments.
