DOS MODE
NOTE :the criteria of doing AUTO-CONFIGURATION : must be a full-size screen, if the screen not full , the auto-
configuration will fail. So in dos mode ,just set your “CLOCK” in OSD-MENU to zero or use some EDITOR
software which can full fill the whole screen (ex: PE2, HE) and then press “AUTO”
Or you can use “DOS1.EXE” which attached in your Driver disk to optimize DOS mode performance

THE PANEL LUMINANCE WAS DOWN
Use white pattern and resolution 1280x1024 @ 60Hz , CHROMA 7120 measured the center of panel
Set Contrast, brightness =maximal, RGB= 50
Quit from OSD-screen, measured Y(luminance)
With chroma 7120, check Y= 240±10 cd/m2 ?
NG
If the Y less than 200 cd/m2 (after the contrast,
brightness = max) then change the LAMP of panel
If Y can reach
