That depends on how far you sit from the TV. At some multiples of screen size you only need 2048p to hit the max for the human eye. At others you need UHDTV. If you don't have good eye sight and sit 3 - 4 X of the TVs width from the TV 1080p is already maxing out the resolution detectable by the eye.
