The NP-PA521U supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) data projector, which is the most common resolution supported by 5000:1 contrast ratio projectors that came out more than two years ago. 640 x 480 (VGA) is also supported by this NEC multimedia projector. In addition, this multimedia 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).
This data projector's resolution (1920 x 1200 (WUXGA)) is actually the best supported resolution amongst all multimedia projectors that have been on the market for a similar time to the NP-PA521U.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution amongst similar types of data projector.
