The NP-M403X supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of the most frequently found supported graphics resolutions of 640 x 480 (VGA) (which is also supported by this data projector). In addition, this projector support supported graphics resolutionss of 800 x 600 (SVGA), 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 768 (WXGA), 1280 x 800 (WXGA), 1400 x 1050 (SXGA+) and 1440 x 900 (WXGA+) and 1600 x 1200 (UXGA).
This projector's resolution (1920 x 1200 (WUXGA)) is in fact the best supported resolution across all data projectors of a similar age and spec to the NP-M403X.
A 640 x 480 (VGA) supported graphics resolutions is the worst supported resolution across similar types of projector.
