The projector automatically determines the incoming signal and displays it in its appropriate aspect ratio.
• This table shows typical resolutions and aspect ratios that most computers support.

VGA 640 × 480 4:3
SVGA 800 × 600 4:3
XGA 1024 × 768 4:3
WXGA 1280 × 768 15:9

tions to fit the screen. Parts of the displayed image are cropped at the top and bottom
edges and therefore not visible.
NATIVE The projector displays the current image in its true resolution when the incoming com -
puter signal has a lower resolution than the projector’s native resolution.
