Selecting a Screen Mode (Aspect)
You can select one of four screen modes depending on the aspect ratio or display resolution
of your computer
If the display resolution of the computer is higher than 1400 by 1050 dots (1024 by 768 dots for X600), select a lower resolution before starting projection.
The upper, lower, left, and/or right portions of a projected image may be missing depending on the Aspect setting.
