20/20 vision is being able to distinguish 30 cycles per degree (at max contrast, it's lower for lower contrast) which is the same as 60 pixels per degree. 40 degree fov comes to 2400 pixels wide, thus 2560x1440p is more than enough for great immersion. |
Keep in mind that 20/20 vision isn't the maximum extent the human vision can go... You can have better than 20/20 and 30 cycles per degree.
