The highest resolution of the Acer P1525 is 1080p (1920x1080). That's over two times the resolution of a WXGA (1280x800) projector, which is the most frequently found resolution. The resolution of all comparable spec multimedia projectors that were released in the last year ranges from SVGA (800x600) to WUXGA (1920x1200).
We think you might also be interested in some of the alternative projectors that have a resolution of 1080p (1920x1080) currently available including the H6518BD, or the H6517ABD both from Acer which is cheaper; or the Acer Predator Z650 ($1,329.99) which has a better Rating.
Projectors with a higher resolution that might be worth considering include the Acer P1623 (WUXGA (1920x1200)).
