According to the help file:
Under Image Scaling, select Enable GPU scaling, and then select the desired setting:
Maintain aspect ratioTurns on Ratiometric Expansion and scales the frame buffer horizontally and/or vertically up to the panel size while maintaining the wide-panel aspect ratio of the original mode.
Scale image to full panel sizeTurns on Ratiometric Expansion and scales the frame buffer to fill the panel.
Use centered timingsTurns off Ratiometric Expansion. If you are using a smaller frame buffer image (800 x 600 resolution) than the native panel resolution, the image displays centered on the panel with black bars around it.
It seems to me that if I had a 1920x1080 display, and selected 1280x720, GPU scaling would scale up to and output 1920x1080. Therefore, GPU scaling should not matter if you are outputting at the native resolution of the panel.
However, I read a post that stated the GPU scaling is also used if the GPU is fed an SD stream, with the GPU upscaling the stream to the window size (or the panel size in full screen). The poster maintained that the quality of upscaling was better if GPU scaling was enable.
Frankly, I don't see much difference, but I leave it enabled.
