It's hard to say -- I'm currently playing BluRay disks through a 720p projector on a 100 inch screen at about 12 feet and I have to walk closer to the screen before I can see any indication of pixels. Not exactly the same thing but if I had a 1080p projector to do A/B testing with I would just retire the 720p and use the 1080p anyways wink
