resolution.
Reasons for Recommending Optimal Resolution : The aspect ratio is 16:10.
If the input resolution is not 16:10 (for instance, 16:9, 5:4, 4:3), you might encounter
problems such as blurred letters, blurry screen, cut-off screen display or tilted
screen.
The setting method can differ by computer and O/S (Operation System),
and resolution mentioned above may not be supported by the video card
performance. In this case, please ask to the computer or the video card
manufacturer
