I have a monitor similar to this (the Viewsonic VX2025wm) and a graphics card capable of handling the widescreen resolution. The changes I needed to make to /etc/X11/xorg.conf were as follows: Section "Monitor" Identifier "Monitor0" VendorName "ViewSonic" ModelName "ViewSonic VX2025wm" HorizSync 30.0 - 82.0 VertRefresh 50.0 - 85.0 Option "dpms" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "1680x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection Note that I'm using an nvidia card with their proprietary drivers, and have no problems at all with this screen. I'm actually considering getting a second one and going dual-head with it. -- During times of universal deceit, telling the truth becomes a revolutionary act. George Orwell
