Can you see "Not
Optimum Mode",
"Recommended
mode : 1920 X 1200
60Hz" on the screen?
You can see this message when the signal from
the video card exceeds the maximum resolution
and frequency that the monitor can properly
handle.
Adjust the maximum resolution and frequency
that the monitor can handle properly.
If the display exceeds UXGA or 75Hz (In case of
UXGA, 60Hz), a "Not Optimum Mode",
"Recommended mode : 1920 X 1200 60Hz"
message is displayed. If the display exceeds
85Hz, the display will work properly but the "Not
Optimum Mode", "Recommended mode :
1920 X 1200 60Hz" message appears for one
minute and then disappears. Please change to
the recommended mode during this one-minute
period. (The message is displayed again if the
system is rebooted.)
