Display scaling
dropdown list
The Display scaling dropdown list allows you to let S3
Graphics software help set an optimized mode for your
DVI output.
Preserve aspect ratio is the default setting. The S3
Graphics software will maintain the aspect ratio and up
scale the screen image as large as possible to the
device’s native resolution.
Note: Even if you have enabled the monitor’s built-in
scaling, the monitor’s scaling will not occur. The S3
Graphics driver does the expansion to the native display
resolution.
Select the Disabled list item to have S3 Graphics
software use the display resolution and refresh rate
requested you specify, without any GPU up scaling. This
setting is appropriate when you want to use the
monitor’s built-in scaling.
Select the Full screen list item to have S3 Graphics
software upscale the screen image to a full screen
image which matches the device’s native resolution. The
aspect ratio may not be maintained.
Select the Center 1:1 list item to have S3 Graphics
software use the GPU upscale hardware to center the
display but do not do any upscaling.
