The Epson EB-1980WU has a maximum resolution of WUXGA (1920x1200). That's over two times the resolution of a WXGA (1280x800) data projector, which is the most common resolution.
This projector's resolution (WUXGA (1920x1200)) is actually the best resolution amongst all 10000:1 contrast ratio data projectors that have been available for the last year.
An XGA (1024x768) native projector resolution is the worst resolution amongst similar types of projector.
We compared all the other data projectors that have a resolution of WUXGA (1920x1200) to this data projector and we think cheaper data projectors such as the Benq TH670S is also worth considering.
