VR Display Limitations

The difference is that your eyes have much higher "resolution" in the centre of your view compared to the peripheral vision. But your eyes move all the time, so unless you can move the screen as fast as your eyes moves, a VR headset needs to have that highest resolution across your entire field of view.

That's not a FOV issue, that's a DOF issue.You can't comfortably use any XR system for more than videos, if you can't use your neck to look around.

Neither really. The VP uses a pair of 4K displays to render a high dpi section where it sense your eyes focusing. This is out of a much wider virtual display space (potentially 360deg). As your eyes and head move it shifts the image through that high resolution area. the space outside that area is rendered in a lower resolution to match your peripheral vision. This technique is called foveated rendering.People who have tried the demos say that it is a seamless experience. Moving your eyes and

You'd need to move your head a lot to look at stuff. Gets old quickly. Try out the VR desktop on oculus and you'll quickly discover the need for much more dense pixels.

foveated rendering should solve this if it can be done well, as you're only rendering high quality where the eye is looking.

Close one eye and focus on something really close with the open eye. Notice that things that are far away are blurry. Now still with one eye open, focus on something far away, and notice that things nearby are blurry. VR doesn't replicate this.

Subpixel AA for VR/AA helps, but it's nowhere near enough. You also need better panels and better optics.

Those 4k screens are at quite a distance right. 2cm in front you will see pixels. Thats why 16k inside ar/vr glasses.

The resolution was probably OK, you wanted lower FOV or higher pixels per degree (PPD). There are monitor replacement AR glasses with the same resolution or lower, but acceptable PPD due to their low FOV.

Have you used a hololens? The small FOV is very jarring.
