Pimax,is there a way you could reduce the mura on the pimax 8kx?Also a black vertical line in the middle

Hey, anyone ever think about the fact that the mura looks like a texture we can focus on with both eyes?

That suggests the mura is not a random effect, but could matched at least between pairs of displays. Which means it might actually be predictable enough to correct in software for entire ranges of serial numbers.

i just tried the quest 2 that i have also here now… But there was no mura to be found…
i hope the pimax can get this also to be the case on the 8kx

Thats a very interesting question. If there is a matching pattern it would mean it could be patched quite easily via firmware. Maybe worth investigating by the technicians.

But i fear “Murphys law” hits and its completely random. :crazy_face:

Well you might be right in theory. If there was a market for faulty 4K-displays having Mura.

But in practice: Who would buy them?
If you had a company using displays, would you buy batches of faulty 4K-displays having Mura? How many? For what purpose?

See, I am working in a steel mill for more than ten years now.
We are producing high quality steels, some million tons per year. But as you can imagine, often enough our melts don’t meet the customers specifications and requirements. Yes, most of them can be used for other spec’s and other products, and then, they will be used alternatively, for sure.
But first: This used to be common practice when I started there - the market’s general conditions weren’t as tight as they became in the last ten years. Since then, many things changed. And second there simply isn’t enough demand for faulty melts any more - we already have supplied the global 20 year demand of flat washers :wink: … further more not being the only steel mill in Germany nor in Europe or the rest of the world :wink:

Of course I don’t know anything about the modern display manufacturing, market and alternative possible applications.

But if it was that easy, why then Mura occurs more often in customer products since a couple of years and the more performant and ambitious the display applications get…? As mentioned by my other refered links, it’s not only Pimax 8K-X having Mura…
According to this

, preventing Mura is getting ever more difficult the more challenging the display application gets. So does the faulty / Mura display rate over the whole display industry increase.
All theoretically wanting to sell their faulty units to someone else :wink:

Last but not least, all my refered links mentioned, Mura was not repairable.
Don’t you think if it was that easy, too, to predict the effect and neutralize it via soft-/firmware, every company whose products are hit by Mura would not already try to do so? This too, would certainly be cheaper than rejecting whole display batches or calm down upset customer complaints :wink:

Of course, it might also be that simply nobody did so yet :+1:

But as Mura existed already long before Pimax 8K-X, I doubt all the display manufacturers just lay back and relax :wink:

Last but not least:
I totally understand you from our customer point of view: We payed several hundreds of Dollars for a high-end VR HMD, and apparently the majority of us is getting suboptimal HMD’s with Mura. That is annoying or even worse, depending on the individual grade of Mura.

But it might well be it is simply not as easy to resolve, sort out or neutralize as we all wish it would be :slight_smile:

Hm, I can’t imagine that there is the same pattern on both panels - should be random on both. Unless it’s no real panel mura but the (same, wrong) mura correction profile applied to two almost mura free panels?

It is there on the quest 2 (at least mine) from what I can see… but it’s extremely faint, enough to not be intrusive, at least better than the 5k+ & ody+ dirty screen look from what I remember.

i cant hardly see it on the quest 2, i also did a test right now to take the faceplate off the oculus quest and put some thin foam inside the quest(without a faceplate)

i did get a much better and acceptable field off view with great clarity… those lenses are realy good!

It is conceivable the Chemical/Physical Vapor Deposition Process, or similar manufacturing steps, introduce somewhat consistent aero/hydro-dynamic turbulence, causing roughly the same thickness variations on each panel manufactured by a specific machine.

sounds like you have encountered this issue. Now i guess we can add Phantom to the list.

I definitely noticed mura (‘dirty panels’) in a few places, but to notice it requires looking at a static bright predominantly single colour image / filter.

For example, the main Squadrons menu often has an orange filter on the background image and then it becomes obvious when moving your head. But in game I would not be able to see it.

Hello @PimaxQuorra will there come a fix for the mura (‘dirty panels’) on the 8kx?
Or is it not fixable?

You would want @Alex.liu to look into tjis question.

Any updates on the situation?

For me the mura,is even more now… its very very distracting…

Its weird I notice it too in Virtual Desktop on the white back ground but then there are times i dont notice it at all in the same situation.

Its like it depends on my mood or something.

Is this something that could even be solved via software ?

Is this thread pointless?

My 8kX replacement arrived yesterday. And mura is about the same as with my last one. Neither worse nor better. So either I have bad luck or this is what it is and one better gets used to it.
For me it’s the same as for drowhunter, only realize it on very bright backgrounds, so in usual use it’s not too distracting for me.
Well, guess we still have to wait a few generations for the perfect headset. Mura here, small FoV or screendoor effect there, or perhaps some grains of Facebook account bondage, we can select our imperfections of choice.
It’s probably best to accomodate with the “good enough” that we have here and now. Or for people who just can’t to sell and wait.
