The monitor is compatible with additional modes within the specified frequency ranges provided that
they are different at least for one of the following :
Horizontal Freq.:
1.0kHz
Vertical Freq.:
1Hz
Note: Even if the monitor detects the input timing as a factory preset mode, the size
and position may not be able to be set as desired. Check the input timings are under the specifications and
adjust the image as you want.
For better quality of display image, use the timing and polarity shown in the table above. Please see your video
card user's guide to ensure compatibility.
