The highest resolution of the Mitsubishi Electric FD730U is 1080p (1920x1080). That's over two times the resolution of a WXGA (1280x800) projector, which is the most common resolution.
A 1080p (1920x1080) native projector resolution is actually the best resolution amongst all 23000:1 contrast ratio multimedia projectors that have been on the market for more than two years.
An XGA (1024x768) native projector resolution is the worst resolution across similar types of projector.
