This monitor does not function with a notebook running at 31.5 Khz( VGA standard).
Running the monitor on regular video cards:
This monitor runs fine on high resolution modes on any video card. It requires a special video
card to run all the lower resolution modes properly on a PC.
(mention that you want -81 Khz setting). We recommend
www.mirage-mmc.com to
support all the low resolution and high resolution modes.
You can run this monitor on normal video cards with the above specification. You must also
use a high resolution mode and refresh rate. This monitor will not work in DOS, Safe mode or
640x480 in low refresh rates without the MIRAGE card.
We recommend that you use your existing system and previous monitor to change the display
settings to one of the high resolutions mentioned below. Please make sure that you also
change your monitor type to one which supports higher refresh rates like the Sony G500
Multiscan monitor mentioned below. Then switch to 1280x1204 60 hz mode on your previous
monitor and make sure that the picture is ok (some small monitors may not be able to run
high resolution and high refresh rates, so if you could not see a recognizable picture, go back
to your previous mode). Once the picture is ok, without rebooting and without turning your
system off, switch the monitors and connect this monitor. You should get a stable picture on
this monitor now.
You may want to go to a different resolutions or higher refresh rates. Windows will switch to
the new mode and asks you to confirm the new mode within 15 seconds. If you can not see
the new mode and do not respond within the 15 seconds, the screen will go back to the
previous mode.
Important Hint: When changing resolutions and refresh rates, change one at a time. For
example to get 1024x768 @85 hz which we recommend on this monitor, first change to
1024x768 resolution. Hit Apply, then change the refresh rate to 85 Hz and hit Apply again.
Try using the following resolutions and refresh rates:
800x600 @ 100 Hz
1024x768 @75, 85, 100 Hz (* recommended mode)
1124x864 @75, 85, 100 Hz (* recommended mode)
1280x1024 @60, 70 Hz
1600x1200 @60 Hz
