Monitor Adjustments
18
V Pos
Moves the screen image up or
down.
Clock
The “Clock “ controls
move the sampling points left or
right while maintaining a fixed
distance between samplings.
These adjustments ensure that the
sampling occurs at the peak of the
input video signal (i.e. neither too
early nor too late), thus eliminating
any panel fuzziness or discolora-
tion. When properly set, all
vertical lines on the panel should
look very crisp.
H WD
Increases or
Decreases the
horizontal screen size (width) by
reducing or enlarging the sam-
pling distance to synchronize the
sampling frequency with the signal
frequency. When properly set, no
vertical banding will be noticeable.
Brt
Decreases or increases brightness
of the backlight.
To save the screen settings for use in
a future session, and through loss of
power or video signal, allow 5
seconds to pass between the last
adjustment and the time when power
is restored to the system. The display
will return with the values you had
last set when the power is restored.
NOTE: The H Wd parameters must
be properly set in order for
the Clock settings to have
their desired effect. The
Clock settings are the final
fine tuning adjustments.
SAVING SETTINGS
NOTE: Cycling the power without
the proper “wait time” will
cause the last value change
to be lost. The previous
setting will be restored
when power is returned.
