The highest resolution of the Hitachi CP-X8800 is XGA (1024x768). That's 23% less resolution than a WXGA (1280x800) projector, which is the most frequently found resolution.
This projector's resolution (XGA (1024x768)) is actually the worst resolution across all 10000:1 contrast ratio data projectors that were released in the last year.
A WUXGA (1920x1200) native projector resolution is the best resolution amongst similar types of projector.
If the resolution of this multimedia projector is not high enough for you then you might also want to look at the Sony VPL-FWZ60 (WXGA (1280x800)), or the Hitachi CP-WX8750 (WXGA (1280x800)) which is also cheaper.
