The NEC NP-PA550 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 data projectors that have been around for a similar time to the NP-PA550. 640 x 480 (VGA) is also supported by this projector. This NEC multimedia 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 in fact the best supported resolution across all comparable spec projectors that were released more than two years ago.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution amongst comparable types of multimedia projector.
