The resolution of your projector is also important especially if you want a cinematic experience at home; if you are working with content at HD resolutions like nop or 1080p then the resolution becomes even more important. For most users an XGA projector capable of 1024 x 768 pixels should suffice. Remember to look at its native resolution; and not the list of supported resolutions as this is misleading. Projectors, like LCD monitors produce the best results when run at their native resolutions. Stay away from VGA (640 x 480 pixels) or SVGA (800 x 600 pixels). An XGA projector will easily handle HD content; but there are nop projectors that work with widescreen content (like HD content) better.
