We can find a pimax 8K advertising on gearbest for 799$.
Is it too expensiv? I think so.
Perhaps it’s explained by the tracking technology if they used the htc vive technology, they have to pay fees.
I would be interested by the headset only but it will probably never sell alone, because it needs tracking.
I’m afraid i will have to pass on the pimax 8k.
And you???
It really depends. Pimax first has to show that they can fix the issue’s with their Pimax 4k driver. If they can’t resolve them, why would it work any better with the 8k ? In that case I’m not going to buy.
If they resolve them though and everything works fine AND it supports native resolution, then I’m buying for sure.
I agress with @Sjef
For the reasons he has mentioned. Also to clarify techniquely it’s Valve’s tracking system.
Now let’s be positive; when the PiMax team works out the current challenges. The cost is quite cheap compared to the competition for these reasons:
But like Sjef said its a matter of solving current challenges.
No oled, bad optics?
OLED’s 4k VR display’s are not yet for sale I think. Not sure what you mean with ‘bad optics’, the lenses ? It would be really nice if Pimax would use some high quality lenses for the 8k. For this kind of money you’d expect them to.
According to the only one test of the pimax 8k that i knows there was some severe distorsions.
I’ve read something about the pimax 8k being very dark. I hope they can resolve that by replacing those damn filters with something not so dark. Not sure I’ve read something about problems with distortions, although now you bring it up, I think it does ring a bell …
AH yeah
“weird inconsistent warping or geometric
distortion when getting farther away from the center of the lenses, an
inaccurate distortion profile in general, a low binocular overlap (the
volume of FOV that overlaps between both eyes), and a very little bit of
ghosting and/or smearing in motion”
I’m not sure if they refer to render distortion though or a problem with the lenses, I’d guess the first.
Anyway, all issue’s they first clearly need to fix before release.
Myself? While Oled is being marketed as the prefered vr solution for display. I am not convinced this is an absolute must.
LG for example from my knowledge does not make an oled panel. & is working with Valve on making the next SteamVR headset.
With Google the new spec for Daydream compatible phones need to have Oled displays to meet the low persistance requirement.
The LG G6 is quite impressive with its 18:9 (2:1) display and i think on Android will do well with VR. But it doesn’t meet the Daydream specification with this display.
As i think you or someone else has mentioned Unity Chan works perfect; which suggests VR implementsion on the game developer also plays a huge part on VR quality experience.
I think while lcd panels have limits with the right balance between controls & display response it can work quite well.
Oled is safe for eyes not led.
Do you have any info on that ?
Are you serious? Why do you think they have to put a filter?
Yes I’m serious, I’m not aware on any info that LCD is more dangerous than OLED. They’ve put that filter because they’re more cautious than other firms in my opinion.
EDIT Hmm although LCD supposedly does emit more blue light than OLED, that could indeed be a factor. I’m not sure how damaging this would be though. Research in this area lacks and I guess we’ll only know after years of VR usage history. But agreed, it’s probably a good idea to have a blue light filter in place, just to be safe.
Surely they don’t have the audacity to charge $700+ after the quality they’ve been outputting so far…
Blue light kills the retina and it’s known for sure now.

I don’t think it’s too much.
Hmm do you have any link on that ? I’ve read the contrary:
"There is some early laboratory research using animal models that suggests excessive blue light exposure can damage some sensitive cell layers of the retina. There is no clinical evidence at the present time that links blue light exposure from digital devices to any pathology or disease of the eye."
I did put my blue light filters back in though, just to be on the safe side. But it’s not a known fact that using a VR based on LCD without filter is damaging. It might, it might not.
Besides, what makes you think the Oculus blue light levels are safe ?
Those Kopin screens are not a valid option, they’re 1 inch, that’s not going to give you a good FoV. Besides they’re not on the market for sale as we speak.
Sharp is developing a 4k" IGZO screen for VR though, but it’s also not on the market at this moment. At least not that I know of.
EDIT that’s not OLED, it’s IGZO, not sure how that compares when it comes to blue light though.
Here for example :
La lumière bleue dangereuse pour les yeux
“Il a été démontré sur un modèle in vitro de dégénérescence maculaire liée à l’âge (DMLA) que la longueur d’onde la plus toxique pour les cellules rétiniennes est située autour de 415-455 nanomètres”, explique le Pr Serge Picaud neurobiologiste et directeur Inserm à l’Institut de la Vision1. Cette zone phototoxique correspond bien à une lumière bleu-violet dans le spectre de l’arc en ciel.Des recherches scientifiques ont conclu qu’une exposition prolongée au rayonnement de lumière bleue ou lumière HEV artificielle provoquait des lésions photochimiques de la rétine et du cristallin. “Plusieurs études épidémiologiques ont démontré que cette lumière bleue était bien un facteur de risque de la DMLA”, rappelle le Pr Serge Picaud2,3. L’implication de la lumière bleue dans le développement de la cataracte est également suspectée.
Blue light dangerous for the eyes
“It has been demonstrated on an in vitro model of age-related macular degeneration (AMD) that the wavelength most toxic to retinal cells is located around 415-455 nanometers,” explains Serge Picaud neurobiologist And Director Inserm at the Institute of Vision1. This phototoxic zone corresponds well to a blue-violet light in the spectrum of the rainbow. Scientific research has concluded that prolonged exposure to blue light or artificial HEV light caused photochemical lesions of the retina and the lens . “Several epidemiological studies have demonstrated that this blue light is indeed a risk factor for AMD,” recalls Serge Picaud2,3. The involvement of blue light in the development of cataract is also suspected.
Interesting then that 3glass s1 uses oled & has customized the panels to reducr blue light.
Might be wrong. However there is currently not enough study to say oled is safe either.
Remember sunlight is not too harmful on its on. But put a magnifying glass n you can burn things.
That’s an ‘in vitro model’, which means not a human model. There’s simply no clinicial (human) evidence about the possible damage. Besides how much blue light is it really emiting, to do you have data ? For comparison, a monitor’s brightness will typically range from 50-400cd/m2 for white. The outside world will typically expose you to HEVL-rich light of between 5,000 cd/m2 and 50,000 cd/m2 simply through reflection.
I’m not saying it’s safe. I’m just saying we don’t have the data like you claim that using VR based on LED without filters is going to cause any damage to us. Time will tell. If you’re really worried you should probably stop using VR at all.
Did you read this???
