Note:
When the input display mode is not 1024x768, the display uses a smoothing and scaling algorithm
to expand the image to 1024 x 768 dots. After expansion from any resolution other than the prime
1024x768 text and graphics will loose sharpness and proper proportion. This panel is not
recommended for extended use at resolution other than 1024x768.
