A 1920 x 1200 (WUXGA) graphics resolution is in fact the best supported resolution across all 13000:1 contrast ratio multimedia projectors that have been around for a comparable time to the MS630ST.
The worst supported resolution amongst comparable types of projector is 640 x 480 (VGA).
We compared all the other data projectors that support a resolution of 1920 x 1200 (WUXGA)|640 x 480 (VGA) to this projector and we think the Benq MW526 ($402.74) which has a better Rating is also worth considering.
If the resolution of this projector is too low for you then you might also want to look at the MX570 ($462.99) (1024 x 768 (XGA and cheaper)|1920 x 1200 (WUXGA and cheaper)|640 x 480 (VGA and cheaper) and cheaper), or the MX525 ($445.48) (1600 x 1200 (UXGA and cheaper)|640 x 480 (VGA and cheaper) and cheaper) both from Benq.
