The highest resolution of the ZTE XMP800 is WVGA (854x480). That's 60% less resolution than a WXGA (1280x800) projector, which is the most common resolution.
A WVGA (854x480) native projector resolution is actually the worst resolution across all multimedia projectors that have been on the market for the last year.
Across comparable types of data projector the best resolution is DCI 4K (4096 x 2160).
We compared this projector to all the other multimedia projectors that have a resolution of WVGA (854x480) and we think a better rated projector such as the Acer C120 ($142.15) are also worth considering.
If you want a projector with a higher resolution then you might want to also look at the Benq MS514 (SVGA (800x600 and higher rated) and higher rated), or the Epson PowerLite 61P (SVGA (800x600 and higher rated) and higher rated).
