The highest resolution of the Acer X112H is SVGA (800x600). That's 39% less resolution than the most frequently found native projector resolution of XGA (1024x768).
A SVGA (800x600) native projector resolution is in fact the worst resolution across all 13000:1 contrast ratio multimedia projectors that have been around for a comparable time to the X112H.
A WXGA (1280x800) native projector resolution is the best resolution amongst comparable types of projector.
We compared all the other projectors that have a resolution of SVGA (800x600) to this data projector and we think the Benq MS514 which is cheaper is also worth considering.
If the resolution of this Acer projector is too low for you then you might want to consider the Benq MX507 (XGA (1024x768)), or the Acer X133 ($655.40) (WXGA (1280x800)).
