The NEC PX800X 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 projectors of this spec and age. 640 x 480 (VGA) is also supported by this data projector. This NEC multimedia projector also supports a graphics resolution of 1024 x 768 (XGA).
A 1920 x 1200 (WUXGA) graphics resolution is actually the best supported resolution amongst all similar spec projectors that were released more than two years ago.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution across comparable types of multimedia projector.
