That’s what I’ve been trying to say for a very long time… 
It could indeed also be a physiological thing. I’ve read reports from people who said the sweet spot increased when getting closer to the lenses. Also read people who complained and then said they had 73 ipd… Yeah that’s just never going to work unfortunately. Either way it’s awesome that mrtv is going to research this, should have done this with pimax headsets too, always wondered if there was much variance among headsets or that it was mostly physiologicaly. And to a certain extend also maybe even psychological, our brain is great at pulling tricks when we compare things, especially when we don’t A/B compare directly, but from memory

What is exactly the problem which @mixedrealityTV is going to investigate? It seems I am missing some context and cannot find it here.

People complain about blurry lens image when looking even slightly away from the center

I’ll note, though, that when I write this, I do not mean something like IPD or face topology – these are only simple “mechanical” matters, that make it harder to wear the HMD in such a way that one’s eyes are positioned in the sweet spots of the lenses, which can usually be overcome with some more or less involving degree of modding effort.
What i am talkng about is something that more directly affects one’s vision, such as the refractive properties of one’s eyes, and how they are governed – so not just the refractive index being off or range limited, but also the field curvature given by lens- and retina cutsection profiles and sizes, accomodation behaviour, and so on. :7
Different users report wildly different percentages of the view appearing in focus for them, with the HP Reverb G2.
…so, being one who find it good, he has called for users who find it bad, to borrow him their devices, so that that he can try them all on and compare his impressions with them, with what he has with his own, in order to determine whether the problem lies in differences from unit to unit.
One might argue that such a test should include testing in the opposite direction, too, across all test group participants, but… :7

I have a 5k+, 8k+ and now a G2. I don’t have sweetspot issues with the G2, my IPD is 65mm and its very clear for me for a good range of the screen. The FOV was awful for me but using an old Pimax replacement face pad and removing the original HP facial interface that has improved dramatically.
I had expected to sell the G2 immediately as I like the Pimax FOV, however I can’t go back on the clarity.
How close is the 8KX to the G2 in that regard, I know its not as sharp but wondered how close you guys would rate it.
Thanks

But wouldn’t that exactly result in that: affected vision, also without a headset? And wouldn’t that cause the same problems with other headsets? I’ve read many reports from people who claim that ‘the g2’s sweetsport is much smaller than my headset brand X’s sweetspot’, while me myself and others don’t experience it like that at all.

Check out some of @NextGenVR video comparisons on this. He has done a lot of testing between the two. He found that the G2 is sharper but the 8kx is close to it. I haven’t tried the G2 but I can say that my 8KX is very sharp when I can feed it the proper resolution. My only issue is that my 1080ti is not strong enough for me to keep all games at 100% resolution. They still look good even when I have to lower the resolution a bit but they really look awesome when I don’t have to turn it down. Of course it’s basically impossible to get one of the new graphic cards right now so I’m not able to use the 8kx to its full potential yet. Does give me something to look forward to though.

Sure - absolutely. We’re all a little bit different, but how light falls on the retina for each of us, is our personal normalities, simply on account on being what we are accustomed to, and have evolved our instances of visual perception around.
With a VR headset, we are bringing in certain unfamiliar elements and limitations. A large aperture lens is introduced into our optical paths, extremely close to the eye, and needs to serve us a good image, even when we move around slightly within its eyebox, by looking around; And the light all emits omnidirectionally from pixels on a singularly distant flat surface, and remain so, even after the effects of the lens; Only refracted to appear farther away, as opposed to the light that reaches you directly reflected from a real world three dimensional environment.
One would think everybody should get the exact same impression out of the 2D facsimilie of a real world lightfield, that comes out of the lens identically for every user, without any need to concern oneself with how the producing part of the optical train adds up with the receiving, from case to case, but I certainly do not have the physics chops to assert so, so am wide open to learn. :7
I have a tiny radius of clear vision in my Pimax8kX, and the 5k+ before that, but much, much less of such a problem with my Valve Index; But then there are others, who claim the opposite – so what on Earth could it be that differs between my case, and their’s? Answers on the back of a postcard, please. :7
Or they can take advantage of generous return policies
here’s the hard question. Even if they knew they weren’t getting a review sample , shouldn’t they WANT the best HMD on the market for themselves anyway?

My G2 arrived today and all I can say is “Wow!”, like as in as much of a wow as when I first even tried VR, it completely blows the 8KX out of the water for me.
Going from a 5k+ or Vive to the 8KX was a big improvement in terms of SDE, though the 8KX was still a washed out grey like the 5k, I would say the 8KX SDE is similar to the quest 2, but with the G2 so far I can’t see any SDE at all, and the colours and blacks are the closest I’ve seen to oled, the G2 has me completely stunned, it’s everything I could have wished for in a VR headset.
I can understand that some people get on well with pimax headsets and seem to like the fov, but for me personally the G2 is just so much better in every way that counts.

@NextGenVR is probably the best guy to answer that question for you, as he loves both headsets, and installs latest updates and firmwares to take advantage of the current features available, and view the headsets as is today rather than at launch. He can give you a fair comparison on them.

Sure but to truly be the best it needs all around good feel from all aspects of customer experience.
However there is also reviewer’s own biases/preferences. Some reviewers review all kinds of things well known and obscure. While others mainly focus only on what is popular
You didn’t get a chance to try the X after the backlight options were fixed up before selling? If so on that side it was ashame as many have reported with the right balance in these settings the g2 vs 8kX is less pronounced. Though iirc the g2 still has better color.
Glad to hear the G2 worked out for you! The 8KX colors are now great for me after the backlight controls were introduced but I know you had a lot of issues with the optics. At least now you can move on from Pimax in peace and just start enjoying VR again. It’s just good that there are so many options out so hopefully everyone can find a headset that they can be happy with even though they all have their strong points and weak points.

my main problem with the X was the black levels, I can’t see how increasing the brightness of the backlight would help with improving black levels, I already adjusted colour, brightness and contrast options and they all had zero effect on black levels. Looking at dmels videos this is still true and the colours still look really awful in comparison
on top of this SDE is completely gone on the G2, and whilst its “good” on the X it really surprised me how much better an image looks with zero SDE compared with almost none

Can I ask what game blew you away the most? Just curious.
Also can I ask what your IPD is?

My ipd is 64
The first game I tried was zero caliber, I spent must have been like 10 minutes just looking at my own gloves and guns, like I couldn’t even believe there was absolutely no SDE, I really really tried to look for it
Half life alyx is also obviously stunning in this headset
I also fired up the blu quickly as that was one the pimax really struggled with in terms of black levels
I’m not sure what the OP’s complaint about wmr is, I actually really like that I can boot the PC, put the headset on and just say “play zero caliber” and the game loads, I don’t need to handle wmr or Steamvr at all once it’s done it’s first time setup, pitool used to give me all sorts of problems having to take the headset on and off and keep re-connecting controllers
I’m also really impressed with the comfort and how the headstrap works, you adjust it once with the straps and then it just hinges up and off really easy, even with glasses, I was assuming I was going to need prescription inserts but now I’m not so sure I need them

THANK YOU!! I dont know WTF is wrong with the Pimax headsets 5K+, 8K, 8KX. I have the 8KX now, I used to own the 8K and 5K+. I could NEVER dial out the eyestrain in any of them, even with the new Pitool that has the 2 different IPD tools I had no luck. I really want to love the 8KX but I simply cannot use it for more than half hour before it starts to wear on my eyes. Somebody said its the canted displays?? My IPD is around 62ish. I just got the headset a couple weeks ago but I might have to sell it, but before that Ill open another “eye strain” thread and see if anyone has any good fixes
