My brother and I have done extensive testing on his 46" LCD TV between 720p and 1080p.

We both concluded that at that size there was almost no difference in PQ between the two, sitting about 10 feet away.

Has any one else found similar results?

I suspect there would be a difference in a front projection system with screen sizes over 80"
