He also show a comparison with 5K XR, 5K+ and 8K (but 8K looks a bit too unsharp, but the pixels looks right compared to 5K+)
When they are wrong labeled, what headsets did we see here? For me it looks right, you can see on all images the subpixel matrix good enough. 5K XR looks like Pentile OLED, 5K+ like RGB LCD, 8K like RGB CLPL and the XTAL like Pentile OLED.
About you could see less of the wheel on the XTAL Image when he explain how it works: I have seen last night a other video about XTAL and it seems the vertical FoV is not as good a the Pimax one, that would explain it. But on the pimax the vertical high of the LCD is not used completely, there is a small black border. Generally near the half of the pixel is not used, what a wast of resolution, but on marketing this unused pixels also counts.
When XAL say "our headset has a 2560 x 1440 per eye resolution" it is absolutely true, when all other headset developer say "our headset has a XXXX x XXXX per eye resolution" they lie to us. But the companies are not dumb, so they only speak about the panels, not about the true eye resolution. But the XAL shows that panel resolution is not what should important for us, the true eye resolution should it.
Right now it is not for game market only because it cost too much (but only you didn't spend x0.000 Euros already into your Motion SimRig) and need more development into the lenses.
Also Pimax has a problem with the 8K headsets: there are no OLEDs with such a high PPI for a 4K panel on the market.
Badly it is difficult to find enough near the same image material about the XTAL to compare it with the Pimax 8K X, so it's hard to say what image looks better. If you look only to the numbers: the 8K X have 3820 Pixels in width, the XTAL only 2560, 1.5x more pixels at the width (also at the height), but many pixels in the Pimax are never used. If i look on that second image, i would say the Pimax should have a higher PPI in the middle, on the border the XTAL should be better.
But one is pretty clear: you need much more graphic power for that advantage and you could use that saved power on the XTAL for better ingame graphic settings. If you want the same quality with the XTAL lenses compared to Fresnel lenses, you always need a much higher resolution (and SS because of that distortion of the VR image) and so much more power with Fresnel lenses. And what we didn't have today is endless graphic power.
But in the end both ways are dead ends, because we need a completely different VR optic in the headsets, that can show true 3D with focus levels so our eyes can look naturally in VR as in RL, because i fear when we stay too long on that cheap Fake 3D we hurt our eyes too much.
