The display scaling controls appear on the Adjust Desktop Size and Position page when you click the icon that represents your flat panel display or non-HD digital display connected to the HDMI, DisplayPort, or DVI connector.
Use these controls to change how lower resolution images are scaled to fit your display.
Aspect ratio - This setting expands the desktop as much as possible while maintaining the same dimensional proportions, or aspect ratio, as the original image. There may be some black borders, but you may prefer this setting to avoid distorting the image.
Full-screen - This setting stretches the desktop to fill the entire display screen.
No scaling - This setting leaves the display image in its original size and centers it on your screen resulting in a small though crisp image. A black border may appear around the display image.
Integer scaling - Available only when scaling is performed on the GPU, and only for NVIDIA Turing and later GPUs. Scales smaller-than-native resolution source by duplicating pixels at the maximum possible integer factor in both horizontal and vertical directions.
