The NEC P401 has a maximum resolution of WXGA (1280x800). That's 30% more resolution than the most common native projector resolution of XGA (1024x768).
This data projector's resolution (WXGA (1280x800)) is in fact the best resolution amongst all 4000:1 contrast ratio projectors that have been around for a comparable time to the P401.
Amongst comparable types of data projector the worst resolution is XGA (1024x768).
We compared all the other projectors that have a resolution of WXGA (1280x800) to this projector and we think the NEC NP-P451 ($1,799.00) which has a better Rating is also worth considering.
