The highest resolution of the PT-FZ570 is WUXGA (1920x1200). That's over two times the resolution of a WXGA (1280x800) multimedia projector, which is the most frequently found resolution.
This multimedia projector's resolution (WUXGA (1920x1200)) is actually the best resolution across all data projectors that were released in the last year.
Across comparable types of multimedia projector the worst resolution is XGA (1024x768).
It may also be worth considering one of the other multimedia projectors that have a resolution of WUXGA (1920x1200) currently available including cheaper data projectors such as the Hitachi CP-WU5505 ($2,229.99).
