2 SCREEN ADJUSTMENT
3. To eliminate dispartities in color temperature and brightness due to
the irregular video signal output
Because of the differences in video signal output levels of graphics boards, disparities
can be seen in the color temperature and brightness of the image shown on the
monitor, even when the settings are the same. Color Correction corrects irregular
video signal output levels to eliminate disparities in color temperature and bright-
ness. This adjustment should be done when a graphics board and the monitor are
connected.
For example, this adjustment is able to adjust tones of the color temperature when
using two computers with a monitor or using several monitors. Differences in signal
level will be corrected and color temperature and brightness will be nearly identical,
regardless of the graphics board used. The setup procedure are following:
· Before the below steps, open a www browser, e.g. Internet
Explorer, and the Pattern.html in the utility disk. For
compensation, if this file is not available, please open a
window on the Windows or Macintosh OS for alternative
use. Set the background to black, and open a white
window whose size is more than 1/5 and less than 1/2 of
the whole display area. Refer to the picture on the right.
Procedure
1) Select “Color Correction” icon from the “Standard”
adjustment mode.
2) Press OK and the monitor automatically starts the
compensation. It takes about 20 to 30 seconds to compen-
sate the color temperature from 4000 K to 10000 K. (All
other adjustments are off during compensation.)
3) When the compensation finished, a long beep sounds and
“OK” appears on the screen. If the compensation fails,
four short beeps sounds and “Error” appears. Both “OK”
and “Error” blinks.
4) Press any adjustment button on the front panel makes this
message menu off.
· Please allow 30 minutes for the monitor to warm up.
· Approximately 20 to 30 seconds are needed to adjust Color Correction.
· Color Correction does not work properly when the input signal level is lower than
0.5 Vp-p or higher than 1.0 Vp-p.
· Please adjust contrast and color temperature adjustment after Color Correction.
