The Acer P1286 has a maximum resolution of XGA (1024x768). That's 62% less resolution than a 1080p (1920x1080) projector, which is the most common resolution. The resolution of all recently released multimedia projectors ranges from SVGA (800x600) to WUXGA (1920x1200).
It may also be worth considering one of the alternative multimedia projectors that have a resolution of XGA (1024x768) currently available including the Acer X125H, the Optoma X341 ($349.00), or the Viewsonic PJD6250L ($392.99) which is cheaper.
Projectors with a higher resolution that might be worth considering include the Optoma H114 (WXGA (1280x800 and higher rated) and higher rated) or the Optoma W331 ($399.00) (WXGA (1280x800 and cheaper) and cheaper).
