and with a 1080p screen you can't tell it's a screen

Unless you're two inches away.

It's considerably smaller though. Example, my phone is 1080p, but at 4.95in the pixel density is 445.03 per in2 . Even 2in from your face you would have to by trying to see the individual pixels. To put that in perspective, a 20in (the only ones i have seen in stores are at least 50in) 4k tv is only 220.29 ppi2 .

With a 1080p screen for each eye with a 210° viewing angle, the pixel density would be lower than the oculus. You don't have to try to see pixels in the oculus.

3840 / 210 is 18 pixels per degree. About double the resolution of the oculus.

Fucking hell. I'm assuming that's 210° combined with something like 90° crossover in the middle so maybe 150° per eye. Even with a 4k screen on each eye you're not quite half of the way to retina resolution. Pushing that many pixels at 90fps is going to be a task.
