Calibrating the Video Gain (6185-D and 6185-N only)
The panel mount (6185-D) and rack mount (6185-N) monitors have a
calibration mode to allow you to compensate for abnormal video signal
levels. Many PC video cards drive the video signal above the .714V as
defined by the VGA standard. You may need to calibrate the video gain
if you see “ghosting” (shadows to the right of the image) or washed out
colors.
To calibrate the monitor:
1. Start the flat panel adjustment utility included with the monitor. For
instructions on starting the utility, refer to Page 45.
2. Press and hold down both luminance buttons for eight seconds.
Note: The screen will go blank after two seconds and will
come back on after eight seconds.
The amber LED blinks slowly to indicate that you are in calibration
mode.
3. Use the left luminance button to lower the contrast until the white
bar stays white and the first light gray bar changes back to light gray.
This is the optimal setting for the video gain. (See the figure on
Page 49.)
4. Press and hold down both luminance buttons for two seconds to exit
calibration mode.
The amber light blinks twice when the calibration is complete.
