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.
