3. Not Optimum Mode
If the vertical resolution is set to 85Hz, you can still see the display but the warning message below appears and disappears after one minute. Since the monitor does not support a vertical resolution that is 85Hz or higher, the monitor goes into “ Not Supported Mode ” and the screen becomes blank after one minute. The user must adjust the frequency within that one minute.
If the resolution is set to UXGA (1600*1200 60Hz), the same warning message as above appears and disappears after one minute, but the display still works properly.
The Reduced Blinking Timing Mode of the Preset Timing Mode is properly supported.
