Click the Start button, point to Settings, and click Control Panel.
Double-click the Display icon in the Control Panel window, and then click the Settings tab.

NOTE: Though we do not officially support the UXGA video mode ( 1600 x 1200 @ 60Hz ),
this monitor will display UXGA. Video performance could be impaired in this mode. The following message appears when
in this mode "Cannot Display This Video mode". In the event the system is in UXGA mode, the user will still be able
to view the screen in order to change the resolution to optimal.
