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 properly
handle.
If the display exceeds SXGA or 75Hz, a
"Not Optimum Mode. Recommended
mode 1280 x 1024 60Hz" message is
displayed. If the display exceeds 85Hz,
the display will work properly but the
"Not Optimum Mode. Recommended
mode 1280 x 1024 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.)
