The Optoma S341 supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of the most common graphics resolution of 640 x 480 (VGA) (which is also supported by this data projector). In addition, this Optoma multimedia projector support graphics resolutions of 800 x 600 (SVGA), 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 768 (WXGA), 1280 x 800 (WXGA), 1360 x 768 (WXGA) and 1400 x 1050 (SXGA+) and 1600 x 1200 (UXGA).
This projector's resolution (1920 x 1200 (WUXGA)) is in fact the best supported resolution amongst all projectors that were released in the last year.
A 640 x 480 (VGA) graphics resolution is the worst supported resolution amongst similar types of projector.
