The highest resolution supported by the NP-PX700 is 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) multimedia projector, which is the most common resolution supported by projectors of this spec and age. 640 x 480 (VGA) is also supported by this multimedia projector. In addition, this NEC 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 projector's resolution (1920 x 1200 (WUXGA)) is in fact the best supported resolution across all projectors of a similar spec and age to the NP-PX700.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution across comparable types of projector.
