The Benq MX763 supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of a 640 x 480 (VGA) data projector, which is the most frequently found resolution supported by projectors that have been available for around the same time as the MX763. 640 x 480 (VGA) is also supported by this projector. Across all multimedia projectors of this age and spec the resolution ranges from 640 x 480 (VGA) (worst) to 2560 x 1600 (WQXGA) (best).
