The Benq MS619 has a maximum resolution of SVGA (800x600). That's 39% less resolution than a XGA (1024x768) data projector, which is the most frequently found resolution.
A SVGA (800x600) native projector resolution is in fact the worst resolution across all similar spec data projectors that were released around the same time as the MS619.
Across comparable types of data projector the best resolution is WXGA (1280x800).
We compared all the other projectors that have a resolution of SVGA (800x600) to this data projector and we think cheaper projectors such as the Benq MS517 is also worth considering.
If the resolution of this data projector is not high enough for you then you might also want to consider the Optoma DX325 (XGA (1024x768)) which is also cheaper.
