The highest resolution supported by the Benq TW526 is 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) projector, which is the most frequently found resolution supported by 13000:1 contrast ratio multimedia projectors that came out around the same time as the TW526.
This data projector's resolution (1920 x 1200 (WUXGA)) is in fact the best supported resolution across all projectors of a similar type and age to the TW526.
Across similar types of data projector the worst supported resolution 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 because of it's better review score, the Benq MW526 (£468.48) is also worth considering.
If the resolution of this multimedia projector is not high enough for you then you might want to consider the Acer X133 (1280 x 800 (WXGA)|1920 x 1200 (WUXGA)), or the Benq MX507 (£277.98) (640 x 480 (VGA)|1600 x 1200 (UXGA)) which is also cheaper.
