[Openchrome-users] Acer AL2423W monitor at 1920x1200

[Ondrej Wisniewski]

I had a similar issue with the CLE266 chip on a 20'' Samsung monitor 
(1680x1050). And the fix for this was indeed a proper modeline !! But 
don't be scared, you can use the command line tool "cvt" 
(http://www.uruk.org/~erich/projects/cvt/) which will calculate the 
modeline for you. You just need to provide the desired resolution and 
refresh rate. This tool is usually installed along with the X.org server.

Note: if you use "Reduced Blanking" timings as used on LCD panels, you 
need to set the option "AllowReducedBlanking True" in the display 
section (?)  (IIRC) of your xorg.conf, otherwise the mode might be rejected.
