20/20 Vision, Uncorrected.
20/15, closer to 20/10, Corrected by contact lenses.
OK, you have to notice Screen door then. I’m sure is minimal though

According to my last visit at the optician in summer last year, my vision is 1.0/1.0, which I guess is 20/20 as you call it. No correction needed and definitely no glasses needed.
Now, first hours with the 8KX back in summer 2019 in Florida, I couldnt see any SDE at all.
Then I started to look for it (especially on white text on top of dark background) and indeed finally I saw a slight pattern of pixels when looking at detailed objects and especially white small text. While gaming, I would never notice this. Until this day, I must say I never really “see” the SDE while doing flight/racing simulators. Staring at a gauge for a moment with my head completely still, then yeah I can distinguish some pattern, but its really something that would never bother me. And I highly doubt people in general will see the SDE at all.
Although, I do see a slight (horizotal) pixel inversion at time, and thats something we are still working to improve or eliminate. Its a minor problem most LCD panel has, just live Valve Index has. Many (or most) people wont see that either, but its curently there.
Either way, unless you spend days pixel peeking instead of enjoying your VR experience, the minimal SDE will never be a problem. Not even in simulators.

The SDE will be like it was on the p4k. You more will notice it from time time on static images. Moving images it will be majority of the time unnoticed.

Yes, exactly, never see or don’t notice it on the index when playing games, so the 8KX should be no problem even IF you could see it.
Maybe get the StartVR One if SDE is worrying anyone, it just came out.

It has been released? If so need to find someone to use @risa2000 hmdq program to scrutinize/verify FoV. 
If you have a link please post it in Other Hmd discussions

Not sure StarVR ONE can beat 8KX in SDE/ resolution, from specifications on the website they have “Full RGB AMOLED” 16 million sub-pixels (whatever it can be), that is far less than 4K. Plus “custom Fresnel lenses”. Unless they are using technology similar to Samsung Anti-SDE.

Agreed howevet keep in mind that psvr also used a combination of a filter with RGB Oled it was very effective like the Samsung’s Anti sde screen. With a good pc to power the psvr with it’s 120hz refresh being fully utilized it in terms of screens is better in some degree in visual quality than og rift and vive.
Could you please tell me what advantage we can get from parallel screens? Also, how do you know that Reverb has better pixel density than 8kX? Both Sweviver and MRTV said 8kX was displaying the better image quality (colors?sweetspot?). Personnally, there is no way I won’t be able to not see immediately (and be a bit bothered by) SDE on 8kX if pixel density is inferior or on par to the Reverb.

Parallel screens is how a majority of games are programed to render as it matches flat panel gaming. The Pixels/subpixel by degree is consistent wear with canted screens it varies from close to farther away.
I think I might have the basics on this. Though there are others like jon (Infinite to beyond blog) and @risa2000 and @Neoskynet that can likely explain it better.
As for color comparisons without special equipment it will vary from person to person as to which one looks better. Ie a photo printed a couple of times on different paper or settings a technically inferior reproduction may “look” better than one that matches perfectly.
Simply put if you put the headset on and it looks great! You as the end user’s opinion is the one that holds the most weight.

If I may specify closer…?
The advantage of a parallel setup is that since both lenses sit facing forward in front of both your eyes, optical alignment falloff is identical in all directions, and identically for both eyes, so if I look to the left, things will blur and distort in the exact same way as if I look to the right, or up, or down, and in the exact same way for both eyes, whereas with a canted design, looking left will cause things to go into focus for the left eye, but out of focus for the right.
The reverb spreads its 2k pixels over a smaller FOV than the 8kX: 2160 (common screen height in pixels, for both devices) divided by 90, is more than 2160 divided by 100. This is a very coarse sort of calculation, that fails to take multiple important factors into consideration, but should give a rough idea, given neither device has particularly radical optics.
I can’t speak for any of the few people who have had the opportunity to test both these devices in depth, but I can observe that in macro through-the-lens photos that SweViver have published, the Reverb does indeed seem (just looking - not actually counting) to have a slightly higher pixel count per degree than the 8kX, but in those pictures the image displayed on the Reverb screen is rendered at significantly lower resolution than that of the physical screen, not making proper use of it.
Supposedly there was a software bug around the time the pictures were taken, causing the image to degrade somewhere along the line, before it got to the HMD.
EDIT:
…so if you see screen door effect in a presumably higher PPD Reverb, but not in the lower PPD 8kX, that could be down to any one of at least three major factors, leaving psychovisual ones out of consideration:
-
The 8kX screens could have better fill factor than the Reverb ones; I.e: less space between the picture elements - “more painting, less frame” (EDIT2: I doubt this one).
-
The Reverb lenses could be clearer than the 8kX ones, allowing you to better resolve the SDE.
-
The lens-to-screen spacing of the Reverb could be better tuned to the focussing abilites of your particular eyes than the 8kX, to the same result as the above.

The problem plaguing the Reverb is the lenses

Man most importantly, a WMR headset NEEDS to adopt the oculus strategy of 4+ cameras on the HMD. 2 camera tracking just doesn’t cut it for high end VR. I really hope HP lead the way with this, because otherwise I find WMR to be very attractive. If a 200 dollar HMD existed with solid tracking and the same res as the oddysey or better, all of my friends would own a HMD.

Tbh I think a 6 camera setup of sorts would be best. With the 2 extra cameras implemented approximately above the ear.
But yes the Rift S does have a much better implentation than the gen1 Wmr headsets.
The new reverb g2 though I believe is said to have Steam Tracking support planned as Valve is in the mix.

That might be resolved with the Valve partnership along with the fixed soft ipd adjustment replaced with Mech ipd.

Not in all situations in the 8kX.
Any space between pixels is airtight. There are some situations in which pixelation is not even visible.
some situations, for sure. Anyway, I will get the 8kX eventually and will confirm. But pretty I will notice Screen door or texture
If you had an Oculus CV1, you might remember the way that tried to minimize screen door effect by using tiny Fresnel ridges to create blur. Which had the side effect of such terrible ray effects, duplication, and haze, that these actually became harder to ignore with time rather than easier.
Pimax Vision 8kX lacks screen door effect in the sense of black lines for a similar reason. The difference of course, is the resolution is so high, it is competing with actually decent optics.

Well I guess it’s the same as on the +
I m not sure if I like the smudge technique to clear SDE. We had some pictures in another thread of an Odyssee+ and the 8k+. Still quite good but more details in the 8K+. While being hard to say by pictures of through the lens (TTL) with different environments, I like the 8k+ from those more then the Odyssey, also sometimes the blacks swallow details… Normally I love OLED.

From what I understand they offer a rather small FOV, have quite rapid falloff of focus away from the centre, and lack lens spacing adjustment. Is this true, and do they have other issues? Pretty sure they are fresnels?
I guess we’ll see soon enough, whether the new model have the same, or similar, lenses as the Index (for better and for worse). :7
