There is a reason my 60" (152.4 cm) 1080p TV is 8’ (243.84 cm) away from my couch. That’s 96" (243.84 cm), and the pixel threshold for a 60" (152.4 cm) 1080p set is 94" (238.76 cm) for the average eye. I can indeed see individual pixels if I get much closer than that. Maybe you should go get your eyes checked if you are in disbelief. Maybe you do need glasses now. The reason that thought enters my mind is you say 10’ (304.8 cm) is enough to not see pixels from your projector, when 10’ (304.8 cm) should be well inside the threshold. Pixels should be very noticeable at that distance with a 1080p screen that size.
