Image resolution
The projected image resolution is 1024 x 768 (XGA). The projector is compatible with screen resolutions
up to 1280 x 1024 (SXGA). If your computer screen resolution is higher than 1280 x 1024 (SXGA), reset it
to a lower resolution before you connect the projector.
Note: The image automatically expands 640 x 480 (VGA) and 800 x 600 (SVGA), SDTV, and HDTV
images to 1024 x 768 (XGA). This expansion can cause some slight blurriness to the image. If this is
a problem, try to change the resolution of the signal source to 1024 x 768.
