How to enable Large Widescreen Support

• 24/23" widescreen monitors sometimes have issues running 1920x1200.
• Examples include: Dell 2405, HP 2335 or an Apple Cinema Display.

sudo gedit /etc/X11/xorg.conf

• Add the following line to the appropriate "Monitor" section

Modeline "1920x1200" 154 1920 1968 2000 2080 1200 1203 1209 1235

• For example the HP2335 should now look like:

Section "Monitor"
 Identifier "hp L2335"
 Option  "DPMS"
 Modeline "1920x1200" 154 1920 1968 2000 2080 1200 1203 1209 1235
