The NP-PX800 supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of the most frequently found graphics resolution of 640 x 480 (VGA) (which is also supported by this projector). In addition, this data projector support graphics resolutions of 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1400 x 1050 (SXGA+) and 1600 x 1200 (UXGA) and 800 x 600 (SVGA).
A 1920 x 1200 (WUXGA) graphics resolution is actually the best supported resolution across all 2100:1 contrast ratio data projectors that have been around for a comparable time to the NP-PX800.
The worst supported resolution across similar types of projector is 640 x 480 (VGA).
