The Optoma EH7700 has a maximum resolution of WUXGA (1920x1200). That's over two times the resolution of a WXGA (1280x800) data projector, which is the most frequently found resolution.
A WUXGA (1920x1200) projector native resolution is actually the best resolution across all 5000:1 contrast ratio multimedia projectors that have been on the market for more than two years.
Across comparable types of projector the worst resolution is XGA (1024x768).
