My Motorola Moto Z phone is basically a "retina display", even taking my
glasses off and squinting at it with my horribly short sighted vision,
I can't see pixels.  Strapping it to my head in a Google Daydream is a
whole other story though, rather low res, not enough resolution to be a
monitor replacement.  Oculus and friends insist on 90 Hz frame rates, to
stop people feeling ill, but lower rates work fine for "never gets ill"
me, YMMV.  4k per eye at 90 Hz frame rate for augmented / virtual
reality headsets is likely coming soonish.  Then again, tricks like
foveated rendering will reduce the amount of high res pixels needed
(tracking what part of the display your eyeball is actually focused on,
and only rendering that bit in high res).  That's driving things a bit
for now.
