The highest resolution of the LG PF1500 is 1080p (1920x1080). That's over two times the resolution of a WXGA (1280x800) data projector, which is the most common resolution.
A 1080p (1920x1080) native projector resolution is in fact the best resolution across all data projectors that have been around for around the same time as the PF1500.
A SVGA (800x600) native projector resolution is the worst resolution across comparable types of multimedia projector.
It may also be worth considering one of the other data projectors that have a resolution of 1080p (1920x1080) currently available including the Optoma HD50 which has a better Rating; or the Optoma HD151 which is cheaper.
