The Ricoh PJ WX3351N has a maximum resolution of WXGA (1280x800). That's 30% more resolution than the most common native projector resolution of XGA (1024x768).
A WXGA (1280x800) native projector resolution is actually the best resolution amongst all 13000:1 contrast ratio multimedia projectors that were released more than a year ago.
Amongst similar types of projector the worst resolution is SVGA (800x600).
We compared this projector to all the other multimedia projectors that have a resolution of WXGA (1280x800) and we think the Benq MW724 (£349.00) which is cheaper is also worth considering.
