It just depends how far you sit. You can easily see the difference with a 32" pc monitor on your desk.

I'm more interested in 4K projectors coming down in price. I sit about 11 ft away from a 92" screen. I can easily see pixels at that distance and size at 1080p.
I did some research some time ago and at around 100 pixels per degree you lose sight of individual pixels with a maximum of 200 pixels per degree beyond which you can't notice any difference anymore.
At 8 ft you need a minimum of 37" diagonal to notice any difference between 1080p and 4K and can go up to 74" before you can use 8K.
9 ft -> 42" to 83"
10 ft -> 46" to 92"
11 ft -> 51" to 102"
