I found this on Sonys site which is intersting.
Their new 1.3" Micro OLED looks to be 3,552 × 3,840 which is 13,639,680mp.
So one could argue this in not technically 4k either.
But hey don’t shoot the messenger lol.

It would be a smart move to update the Pico4. Hope it has some worthy updates.

Errr… this is like complaining that a car hasn’t got a 6 cylinders in a row engine - while it has a V8. Where you trying to laude the AVP for its resolution in your original post? If yes, I failed to recognize that.
Agreed it doesn’t mean much when the resolution is spread almost evenly onto a square panel.
I’m not anti AVP as it’s the best Micro-OLED HMD you can get right now and I can understand people getting defensive after spending 4k.
But looking forward when FOV gets wider will manufacturers like Pimax stick to 16:9 panels like in the 8kX? Might we see wider panels maybe 2:1 with Hypervision lenses? Even if they use 2 panels per eye we’ll have to add that resolution together.
Imaging 4x 1” Micro-OLEDs at 2560x2560 per panel. That’s 10k wide in Pimax speak but only 2.5 high.

It’s not always about resolution, also lenses are affecting the observable PPD by a huge margin.
Look at the XTALs, same Panels and resolution like the 8KX, but PPD like the Aero. It is really astonishing to me how this is achieved by the XTALs and to some way for me magical. I can really see no pixels in the XTAL 3, where I could see some with any other HMD including the Aero ( only backlighting pixels as Murra tough).

But how big are the panels in the XTAL3?
I think the Pimax 8kX are 5.5” so it’s no wonder the SDE is small.
What we’re talking about with the Micro-OLEDs is a 10k resolution using pancake lenses in a HMD as big as a Pico4.
Now we’re hitting Micro-OLED mass product I’d expect prices on 1.3” displays to tumble especially with LG coming onboard.

If I am not wrong the panels are sharing the same size like the panels of the 8KX, so 5.5"
The SDE of the 8KX is minimal but still observable, with the XTAL 3 pretty much gone.
The pixels are roughly twice as small in the XTAL 3 compared to the 8KX, as in one VR scenario I could saw them, but 99% the time you can not see them no matter how hard you try to see them (I have perfect vision and eyes btw).
What I can see often though is a little Murra with my XTAL 3, but these 2160p 5,5" LCD Panels always have some.
So basically you have with the XTAL 3 a Pimax 12K, FOV and resolution wise, but with the big advantage of a FPS performance like having with the 8KX + while having a full native resolution.
I am really looking foward to the HyperVision 240 lenses, but these are some years away to be implemented into a HMD. The four seperate display panels are/ will be very difficult to be implemented into Steam VR. I am currently not really sure which VR manufacture will use the HyperVision lenses for the first time in a VR HMD. Vrgineers will most likely improve their current lens design for the XTAL 4 to achieve 200 degree hFOV and maybe with 7K Panels for each eye, but I do not think they will use the HyperVision lenses for the XTAL 4, maybe at the earliest with the XTAL 5.
That is for sure and I really hope for decreased prices as well.

The size of the panel itself is not the key factor. As you not looking at the panel directly. You would need to know the Projected screen size. The larger the projection like a projector that uses mobile size screens.
Think of a 1080p projector. The larger the projection the lower the PPI becomes.
The Xtal has the advantage of much higher quality lenses.

You’re completely right with that and I forgot mentioning about that.
The thing with XTAL lenses is that they are improved nearly every year by VRgineers and Pimax did not really did that with the Pimax fresnel lenses. They want to keep the 2160p resolution at all costs for the XTALs, as even with a 4090 you are coming very fast to performance limitations for that massive wide hFOV. The 2160p panels are on it’s self awesome display panels and they have great colors and good blacks. So the approach by VRgineers with improving the lenses instead of increasing resolution is really nice and very intelligent TBH.
I think the XTAL 4 will arrive at first in 2 to 3 years from now. If they will release on the way to the XTAL 4 like a updated XTAL 3 with 200 degree hFOV , I would be highly interested into that or they can upgrade my current XTAL 3 unit with the new lenses.
I just love the XTALs for this modularity and many more reasons, so I am sorry for me being such a fan boy of the XTALs ;), because I am really a XTAL Fan Boy

No need to be sorry. Tbh it was well discussed prior to the KS to have easy to change lenses for lense replacement & upgradability. Unfortunately pimax didn’t listen until the Crystal.
While they added a pass through mode. It is too bad they didn’t use better cams. Opting instead to later on create an Mr faceplate; which isn’t necessary if they had the foresight. Though imagine that was a decision to have an item to purchase later…
@Djonko had discussed the virtual resolution of the project screen back when this was branded as pimax forum.

If you were referring to me re getting defensive, I really am not even though I spent way more than 4K to get this product into Germany.
I spent even more on the XR-4 and am extremely disappointed at what it is right now, calling a spade a spade.
What I am saying though is that the AVP is such a remarkable product when actually using it that it is simply beyond comprehension to me how any VR enthusiast can offer an opinion on it without having experienced it.
We are the very crowd that knows how good specs on an HMD can still lead to a terrible experience when actually using it as it’s a wearable and there are so many more variables to get right compared to pretty much any other electronic product in order to achieve an optimal experience.

Enthusiast already has a number of creditable outlets of users and professional media. Plus there are different types of VR enthusiasts and for now AVP is not for Gamers.
Yes AVP does have some nice things but ATM there apps for it are still small which is to be expected as it needs time.
Don’t discount other enthusiasts as not knowing there stuff. Hard core VR gamers are also quite aware. And for now it just don’t fit there requirements.
This topic has an article regarding a Surgeon using AVP. Which is quite cool as it was discussed this kind of application in 2017 Immersed in Toronto So while not a new idea; it is finally bearing fruit on the idea.
Your disappointment with Varjo is a bit of change as you were once very positive about them. I am guessing the XR-4 must have really dropped the ball vs earlier model?
