3. Select the output resolution that matches the optimal resolution of the
display device (optional).
NOTE: Most LCD, Plasma and DLP displays are not able to auto sync (fine tune)
the incoming video for optimal video performance. The CNX-DVP4 provides setup
screens that allow the user to 'fine tune' the display device. These screens are
accessed by using the Vertical Lines, Color Bars, Gray Scale, or Grid buttons.
NOTE: Always adjust Grid first, then Vertical Lines.
Grid – most displays have Horizontal and Vertical sizing and positioning
adjustments on the display setup menu. Adjust the display so that grid's white border
is edge-to-edge for optimal resolution.
Vertical Lines – most displays have Coarse or Clock and Phase or Fine Tuning
adjustments on the display setup menu. Adjust as needed. The vertical line test
pattern should look uniform. If you see dark vertical bars in the test pattern, adjust
Coarse or Clock to eliminate bands. If you see only horizontal noise, adjust Phase or
Fine to reduce or eliminate noise. You may also need to perform the vertical line
adjustment again after changing the size of the display image.
Color Bars – most displays have Brightness, Contrast, RGB Level and Black Level
adjustments on the display setup menu. Adjust as needed.
Gray Scale – most displays have Brightness, Contrast, RGB Level and Black Level
adjustments on the display setup menu. Adjust as needed.
NOTE: The output can be adjusted in two ways, from the menu and in Viewport. To
access the output command in Viewport, type: output
At the prompt, enter the first number for a standard VGA setting, for example,
