Pixel resolution of HMD without stating FOV is useless. Much better unit of comparison is pixels per 1 degree (PPD).
Original HTC Vive (2016), which was basically the first gen VR product, was 9.81 PPD, current Vive 2 Pro (2021) is 20.4 PPD. Oculus Quest 2 (2020) is 20.58 and currently the best is Varjo VR-3 (2021) with 70 PPD for central display and 30 PPD for peripheral display. Pimax 8K is 22.58 PPD.
- caslon 5y agoI know, and I was thinking about being more explicit, but Zamalek's comment was on resolution per-eye, so to keep it clear I decided to use resolution, too. Thank you for expanding on the comment!
- formerly_proven 5y agoThe Varjo VR-3 is a variable rate display but the zones are fixed, correct? So the locus of fidelity is always in the same spot relative to your eyes? I'm wondering whether VR display technology would benefit from the scan flexibility that some modern image sensors have. E.g. imagine a 12K display where you can select on a frame-by-frame basis which area you want to scan at full resolution, which at half, quarter, ... etc. -- be quick enough about it, and it'll always look like a 12K display but with a fraction of the bandwidth and compute cost.
- mlajtos 5y agoYes, the high resolution display is always fixed in the center, it doesn't move according to your gaze. I can't really comment on the other thing you are proposing...
