2.5.3 Setting Display Resolution
To view a program at a specific resolution, both the video
controller and display must support the program and the
necessary video drivers must be installed.
Before changing any of the original display settings, note
the original settings for future reference.
Start > Control Panel > Pick a category > Appearance
and Themes.
Under Pick a task..., click the area you want to change, or
under or pick a Control Panel icon, click Display.
You can try different settings for Color quality and Screen
resolution.
If you choose a resolution or color palette that is higher than
the display supports, the settings will automatically adjust to
the closest possible setting.
