In recent releases some default mode lines stopped being generated, so
that just requesting a higher resolution in your xorg.conf file won't
work. You also need to define appropriate mode lines as well. You can
use cvt (or a couple of other programs) to generate mode lines that
won't fry your hardware and add them to your xorg.conf file. I have
a couple of monitors that I need to do that with.
For example:
# Xorg configuration created by system-config-display
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
Section "InputDevice"
# keyboard added by system-config-display
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105+inet"
Option "XkbLayout" "us"
EndSection
Section "Monitor"
Identifier "Monitor0"
ModelName "NEC MultiSync LCD2010X"
HorizSync 31.0 - 80.0
VertRefresh 56.0 - 85.0
Modeline "1280x1024_70.00" 129.00 1280 1368 1504 1728 1024 1027 1034
1069 -hsync +vsync
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "nouveau"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"

SubSection "Display"
Viewport 0 0
