if the image posted earlier is correct and the 5k used nearly double the number of pixels of native resolution then the 8k indeed has no business existing as far as i am concerned. They would be better off releasing 5k plus now, sorting out the 8k and releasing it in 6 months to a year, with a modified industrial design to place screen a cm or 2 further from eye and bring the screen usage in line with 5k plus.
All this information has already been public for a long time in the forum, even revealed by the testers themselves. I assure you, I analyze very well how far I can explain.
This doesnāt hurt anyone anyway. It only increases understanding of why a lens with other features might be better. We are even seeing it in StarVR what is the way forward with regard to lenses. If you read my proposal, it matches StarVR lenses a lot, before StarVR showed images of their headset and lenses.
Knowledge is not bad and frees people. Encouraging @Sjef to keep researching is good. Progress is good. I wish more people would do what youāre doing @Sjef
If you read my message history carefully, what youāll see is that Iām saying that the Pimax 8K headset is a wonderful piece of work and that even though weāre not taking full advantage of it right now, it has enormous potential for improvement. Not only with regard to the lenses, but also the upgrade to 8KX, and even the possible exchange of screens by OLED with 4K/UHD resolution.
In the Spanish forums there are many detractors of Pimax 8K, and I put the great potential of Pimax 8K in front of everyoneās face. In those forums they call me āthe unconditional supporter of Pimaxā. Yes, I am critical and demanding, especially with the image, but where I see that something is good, I say it clearly and loudly. And the Pimax 8K is now good enough and has enormous potential for improvement.
If Pimax reads to me, he knows that all this is good for Pimax and Pimax 8K sales. And you can take advantage of all that to make improvements, which many of us will gladly pay for.
The Pimax 5K+ is also good for those who want a headset that surpasses the current headsets like Vive and Oculus. And I think itās ideal for most of the 6,000 backers. To my friends who are not VR freaks and who donāt want to disassemble and experiment with their headset, and when they want a better one, they sell their current one and buy their new one, I recommend Pimax 5K+. Itās good, itās easy, it works well, you need less GPU power, and you can sell it better for its lower price.
About the 50% screen usage, itās not exactly like that. It should be noted that there are two screen areas, a sharp central and a blurry peripheral, in addition to other factors such as software FOV. All this is public and Iām not explaining anything new. Thatās why Iām encouraging @Sjef to keep experimenting. And I still think thatās very good.

Then donāt tell him his image is correct and he just needs to add 4k image. holy shit.

If you look at what sje posted. and understand what he posted, then you would say the 8k is a deeply non optimal design.
It would be like selling someone a 8k tv, and the bezel of the tv covers literally half the screen, and uses half the volume of native res of 5k to form the final image on top of that. which would be regoddamndiculous.
But apparently when a tester confirmed it as correct what they meant to say was it was in fact completely wrong .
wrong on the guess at panel utilisation. wrong on the guess of native res utilisation.
Thatās how you get mass hysteria. testers carelessly confirming shit they like the sound of but which they literally know is wrong, and admit is wrong when called out on it.

I absolutely canāt believe the 8K is using only 50% of the screenā¦ whatās all this about?
its not. the tester incorrectly suggested sjeād panel utilisation image was correct then when called on it said
which means its way more than 50 percent and probably the 80 percent pimax has said it was all along.

Pimax 5K+ seems to have a good design and makes good use of the screens (probably due to its more suitable form factor). According to the Berlin backers, there is currently not much difference between Pimax 5K+ and Pimax 8K.
Why donāt you go get the Pimax 5K+? From everything youāre explaining, it seems a lot more reasonable.
I donāt think Pimax 8Ks need to stop manufacturing and create a new design. I think they need to be launched now. New improvements to realize their full potential will come in a few months or next year. The Pimax 8K is a product for the more geeky.
Honestly, I think most backers would have to order the Pimax 5K+.
And again, it is not correct to say that the Pimax 8K screens use 50% of the screen. There are more points to keep in mind. I canāt explain them because Iām under NDA. In two weeks if all goes well I will be able to explain it, and I will enjoy talking to @Sjef and everyone else who wants to participate. And if Iām wrong, Iāll admit it (Iām human, like you).
But it is not a negative thing, it is a positive thing. Itās a chance for improvement, but again, only for the most geeky.
Itās as if I buy a BMW car for $50,000 and they tell me that in the future for an additional $15,000 I will be able to put super-interesting accessories, such as autonomous driving, electric wheels, electric battery with double capacity with half the weight, etcā¦ I donāt see any of that as a disadvantage or a problem. Now I can enjoy my BMW car and within a year I will be able to improve my BMW car.

Then donāt tell people who say the screen usage is 50 percent they are correct in the first place. Edit your reply to tell them, their guess and calculations are incorrect, instead of telling them they are correct.
YOU are the one who told him his image was correct. you do understand that.

Yeah, I want some too.
Unfortunately they do not yet exist for sale, and seem to be only in the laboratories. And if they were for sale they would be really prohibitive because of their high price.
These OLED 4K/UHD displays are not interesting for mobile phones and that slows down their development. But as VR grows, it will become increasingly profitable to manufacture them, and with mass production, they will become more economical. But Iām afraid weāll have to wait at least 3 to 5 years (hopefully no longer) for it to be affordable.

I will try to calculate the math again from this picture
If we convert the calculation.
4.4M used pixel = 50% of 8.85M pixels.
What will happen if we decrease the size of panel such as 8.85M pixel to be 6M pixel.
Then 4.4m pixel / 6M pixel = 73%
Then 70% of 1440 p = ??? (sharper?)
What anything will change? And 8k to be 6k still be good for sde or not because I think the sde is relate to the PPI? Can we change the resolution without changing the PPI?
If you try to make a wide fov hmd like pimax 8k, you will find out how Pimax has done a great job.
And we are out of the topic.

The image has been confirmed to be completely incorrect in regards 8k panel usage. please donāt base any further calculations off it, the situation is confused enough as it is.

Maybe, so we wait to know the real cause from pimax engineer.
I am not sure that the 50% will be correct because if we decrease the panel to be 50% of usage which they assume. That mean it will become 100% usage and 100% of 1440p which better than 5k+panel. I am suspect that it is correct equation or not. I still not clear about upscale process too much, try to think more.
I feel that although it use 50%, it still have some mistake of calculation.
Done.
I agree with you and have modified the message and added the following.
I edit at the request of @destraudo to add and clarify the following:
About using 50% of the screen, itās not exactly like that. Note that
there are two screen areas, a clear center and a blurry peripheral. Now
in your green box youāre just drawing the clear center area.
If you do the same drawing for the Pimax 4K you will notice that
there is only a clear central area and no blurred peripheral area. With
the Pimax 5K+ and 8K it is necessary to add an additional frame with the
blurred peripheral area corresponding to the peripheral FOV. This is
the added bonus of the new headsets.
You also have to take into account other factors such as different
lens magnifications, software-selectable FOV, eye-lens alignment, IPD
displacement, etc. into account. This is all public and Iām not
explaining anything new.
@destraudo, thanks for helping me get better.

The guys ask me, and I answer.
@Heliosurge, could you move all these messages to Shanghai Surprise?
http://community.openmr.ai/t/shanghai-surprise-neoskynet-directors-cuts/7699/64
I think they are the most appropriate place, being general information about screens and lenses, which broaden the knowledge of colleagues.
Sorry for the inconvenience to all our colleagues.
@Digital, as a family member, you know that I am programmed to always speak with respect, I donāt get upset with other peopleās opinions and if one of them is different from what I want to hear, I try to learn because I may be wrong.
I never tell anyone to shut up because I donāt like what heās saying, nor do I kick him out of anything. And this not only in the forum, but also in real life.
Anyway, thank you for your comments, because it is always good to know other opinions to better balance my neural network.
Cheers,

If the 5k+ is 9% sharper than the 5k. .then the 5k+ utilizes 89% of the screen.
54.5%-59% & 30%-34.9% in the peripheral.
The 8k at 80%. 50% main view area & 30% peripheral.
Yes. The tester has edited their post to reflect this at my request. The 8k uses way more than the native res sjeās image suggests to form its final image

With the physical panel size being originally the same both would have the same utilization.
The 5k+ increases in utilization due to the panel being smaller.
If you use a 5" base panel size for the 8k the 5k+ would have an approximate panel size of 4.5". The 8k would have 80% (based on pimax update) & the 5k+ approximately 89%. (9% sharpet than 5k)

80 to 89% is an improvement of 11%
