WXGA (1280x800) Native Projector Resolution

The highest resolution of the NEC NP-P451 is WXGA (1280x800). That's 30% more resolution than the most frequently found native projector resolution of XGA (1024x768).

This data projector's resolution (WXGA (1280x800)) is in fact the best resolution amongst all projectors that have been around for a comparable time to the NP-P451.

Amongst similar types of data projector the worst resolution is XGA (1024x768).
