The Optoma EH320UST has a maximum resolution of 1080p (1920x1080). That's over two times the resolution of a WXGA (1280x800) data projector, which is the most frequently found resolution.
This data projector's resolution (1080p (1920x1080)) is actually the best resolution amongst all multimedia projectors of this age and type.
Amongst comparable types of data projector the worst resolution is SVGA (800x600).
We compared this data projector to all the other multimedia projectors that have a resolution of 1080p (1920x1080) and we think a cheaper data projector such as the EH319USTI ($1,648.98), and the EH319UST ($1,470.98) both from Optoma or you might consider a higher scoring data projector such as the Sony VPL-HW40ES ($1,563.03) are also worth considering.
