Hello
I think you could just edit your current xorg.conf and add (or modify if they're already existing) to the "Monitor" section something like this:
HorizSync 31.5 - 80
VertRefresh 59-75
Play around with those max frequency ranges if it still doesn't work.

or use ddcprobe to see what your monitor can handle in the way of resolution and refresh.. I have noticed that the use of a KVM blocks the system from probing the display, just in case you are using a KVM.. If you know the resolution and refresh rates of your display use cvt to calculate a modeline for the proper settings..


Code:
it-lenny:~$ cvt  1440 900 refresh 60
# 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz
Modeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync
insert the modeline info into your xorg.conf and away you go !!

hope that helps..


85 is a very high refresh rate for most displays.. typical LCD refresh rates are 60, 70 or 75
