Configuring Video Setup 33
Publication 6185-5.1
Monitors with this a full range dimming control option 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. Insert the diskette provided with the monitor in the floppy drive of
the host computer.
Note:
The adjustment utility is designed for 32-bit operating
systems only (Windows 95/98/2000 or
Windows NT 4.0 or greater).
2. Start the screen setup utility using the instructions on the diskette
label.
3. 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.
4. 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 29.)
5. Press and hold down both luminance buttons for two seconds to exit
calibration mode.
The amber light blinks twice when the calibration is complete.
