Edge Timing Adjust Submenu (sample)
Using this menu, you can set the exact locations of the active video edges, when
1:1
Sample
is
Off
. For the right and left edges, the values are in pixels, and the position is
relative to the start of H Sync. For the top and bottom edges, the values are in numbers of
lines, relative to the start of V Sync.
Because
1:1 Sample
is off, the image is oversampled, and the image quality may be lower
than when
1:1 Sample
is turned on.
