The NP-PA500 supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) projector, which is the most common resolution supported by 2000:1 contrast ratio data projectors that have been on the market for around the same time as the NP-PA500. 640 x 480 (VGA) is also supported by this projector. This data projector also 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 amongst all 2000:1 contrast ratio data projectors that have been available for a similar time to the NP-PA500.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution across comparable types of projector.
