Interval between
VGA signal auto
adjustments, sec
Change the interval between automatic adjustments if you want
them to occur more or less often. To suspend automatic
adjustments, enter 0.
Vertical shift
Configure vertical shift to offset the captured image position. For
example, a captured image shifted slightly downward (vertically)
can be corrected with minor adjustments to the vertical shift
settings.
Increasing or decreasing the value entered in the Vertical Shift
field shifts the image up or down.
Horizontal shift
Configure horizontal shift to offset the captured image position.
For example, a captured image shifted slightly to the right
(horizontally) can be corrected with minor adjustments to the
horizontal shift settings.
Increasing or decreasing the value entered in the Horizontal Shift
field shifts the image to the right or left.
Phase
Configure phase (also called sampling phase) to adjust the
horizontal resolution of the image. Improperly adjusted phase will
result in a fuzzy image. You can adjust the sampling phase in
small steps until a sharper image is displayed.
PLL adjustment
Configure PLL to adjust the vertical synchronization properties of
the image. The PLL adjustment may need to be changed when
there is a repetitive distortion or blurriness on the horizontal axis
of the image. You can adjust the PLL setting in small steps until a
sharper image is displayed.
Offset
Use the offset and gain controls together to optimize image
quality. Increasing offset reduces background noise but also
reduces the overall signal.
Balance offset and gain to achieve the best quality image. You
should adjust these settings by the smallest values possible to
