7. The entire screen appears too dark
or bright.
Adjust the <Contrast> (Contrast and
Brightness).
Try changing the setting of the fine contrast
mode. (p. 15)
Video Signal level from the PC may not match
the monitor. Set the video signal level using the
ScreenManager.
Turn off the monitor, then hold down the down
arrow key while turning on the monitor again.
Some signal timing can be the cause of this
problem. This will change the signal timing and
brighten the screen. If the above operation is
repeated, the screen becomes dark again.
Execute the <Color Restoration>. (p. 16)
8. Color is abnormal.
• The entire screen appears bluish or
reddish.
• Color purity is not uniform.
• Misconvergence of colors (red,
green, blue)
When the monitor is not fully warmed up, the
screen may look slightly colored, e.g. bluish or
reddish. This phenomenon is due to the
unstableness of the electron gun during its
warm-up period. Wait for about 30 minutes
until the monitor stabilizes in order to gain its
proper color.
Adjust the <Degauss>.
Return the factory default setting by using
<Reset>. Note that all the ScreenManager
parameters will be returned to the factory
default settings. (p. 30)
Adjust the <Uniformity>.
Try adjusting the <Convergence>. The
<Convergence> function adjusts the entire
screen. It is not possible to limit adjustment to
specific screen areas.
Execute the <Color Restoration>. (p. 16)
9. <Color Restoration> does not work
properly.
Allow the monitor to stabilize for at least 60
minutes before executing this function.
Otherwise, the warning message "Still Warming
Up! xx minutes remain" will appear on the
screen. (p. 16)
10. ScreenManager or AUTO/FINE
MODE button does not operate.
The Adjustment Lock is probably on. To
unlock: Turn off the monitor power, then hold
down the AUTO/FINE MODE button once
again and turn the power back on. (p. 19)
