Yeah, I'm not sure even this one is going to really be high res enough to make a good monitor replacement, but the other hmds I've seen certainly aren't.

11.5Mpx per eye I think it said in the video. Or almost 50% more than 4K, per eye.

  That's still not capable of producing a central "work area" the angular size of a book at the reading distance with a reasonable angular resolution figure.

    If they alternate eyes rapidly, like active 3D glasses do, couldn't that double or nearly double the perceived resolution (if each eye is offset by 1/2 pixel from the other)?

    Speculating but what if this screen pixel density is not uniform but much more dense in the center and they use eye tracking to shift those screens mechanically similar like the shift camera sensor array for image stabilization?

      Google saccades. No chance eye movement can be reacted and catered for fast enough.
      - pzo 3y ago
        From wiki: >Saccades to an unexpected stimulus normally take about 200 milliseconds (ms) to initiate, and then last from about 20–200 ms, depending on their amplitude (20–30 ms is typical in language reading). Are you sure? Seems like plenty of time - even current iphone camera since many generations have 240fps and most android even handle 720fps mode - current iphones should handle it probsbly even in software (except their camera has quite high latency last time when tested) but they handle it in hardware R1 chip anyway. Since they using probably something like truedepth IR pattern projector, with 720fps grayscale camera should be easy to have very fast motion detector just checking only regions around dots

        You'd have to process and mechanically move some lenses and screens at around 50hz in sync with moving imagery.

        Yeah definitely this would be the most tricky part, but someone mentioned here those screen are the size of post stamp - so if that's true they probsbly closer than lenses in standard correction glasses and the shift wouldn't have to be that big

1080p per eye resolution[0], not really a proper display replacement. Works pretty well for games and media though, these are semi-popular in the Steam Deck community. These also have zero processing and require a device to connect to, there is no positional tracking either so the display floats wherever you move your head to.
