I just tried the Pimax 8k (Pimax 4K user perspective)

Yes, positive, 2 HDMI. They mentioned again the final model will have DP.

Definitely. Hardware IPD is a must.

Well, SDE is a factor of # of pixels / FOV. The FOV has sort of doubled, but so has the number of pixels (since there are 2 screens) so, overall, it’s about the same.

Sorry I was sleeping :slight_smile:

Ok, this is when being a professional reviewer actually helps so I’ll try. Better than Pimax 4k out of the box, no question. Similar to something like say a Nexus 5. I mean a medium tier phone screen. The environment is dark so it’s not like looking at your phone a sunny day, it’s more like if you set your phone’s brightness to 70%, turned all the lights off and put it right against your eyes :slight_smile:

can we have a picture/photo looking through the 4k version LCD using project cars or some “hard to see in the distance” game? I’d also like a virtual desktop photo just to understand what we’re talking about

Definitely not a proper review or even preview of the Pimax 8K. He’s been copying random snippets and images, such as the exploded view of a 4K and brain warp description with the 4K’s exposure rate. Also claims the 8K has a “powerful computer system” on board, which at best is conjecture from a mistranslation (the recommended GPU spec). Not going to bother digging through that for further details.

I’m not really an attention seeking person but I guess I’d be skeptical too. I added some pics, sorry for the delay - I had to pick the ones in which I look good! :smiley:

BTW a bunch of people are testing this now (see the recent post by Pimax asking for people in the San Francisco area) so I expect more (and probably better) reviews coming.

Sorry about the confusion, jjvvgg! My disparaging comment was regarding the veditto link d3stroyah posted. I do not have such reservations regarding your account that started this thread; it seems helpful within the limitations that can be expected of subjective comparisons and a short testing opportunity.

Oh yes, I realize that now. My bad! :stuck_out_tongue:

Then perhaps i don’t understand your confusion.

how is the immersion? did you feel you were there

Hey by powerful computer system inside they are refering to the onboard ARM cpu & rest of the internal mainboard.

As i understood he is using his 4k headset with no shutter glass and probably with supersampling (like many of us), therefore the ‘picture resolution’ looks very similar and he is simply not able to notice any improvements compared to 4k headset. If you remove your shutter glass from 4k you will notice a much clearer picture, lots of brightness and colors as well, however its not how it’s intended to work, so if you compare 4k version and 8k version with no tweaks - you must be able to see improvements.

In addition to this you should never forget that software resolution is not only limited by a driver or cable, but also by a rendering engine, in some cases (i think) it simply wont give you a proper resolution even if hmd using native 4k (its like running full hd game from early access on your brand new 4k resolution monitor).

p.s. As i mentioned before pimax8k is all about less ghosting, extremely high fov, frequency, mods, tracking system and so on. Resolution is something you will have to tweak manually using supersampling because there is never enough of it (playing a game in full hd on a full hd monitor looks not perfectly too, thats why we have anti-aliasing, dsr, downsampling and sh1t ton of other features as solutions to improve resolution and picture quality in desktop games and vr as well)

You are right but here come the trick, the Pimax 8K used for reviews is without shutter glasses too but they do not specify if at the end they will be mounted (despite we have asked several times), this is a key point that has to be clarified, maybe the coming review will tell us.

Can’t the shutter glasses just be removed?

It can, however it has some cons too. Search this forum for “shutter glass”; there is a big thread and lots of discussions.

Shutter glass wont comeback, its mounted only to decrease ghosting on a 4k panel. Since current 8k prototype has almost no ghosting thanks to new displays — there is no sense in mounting shutter glass back. Thats the overall improvement and difference between 8k and 4k.

Are you saying there’s no shutter glasses solely on the fact that the displays are custom made? We need to stick to facts before we throw money at something that may not be what your expecting. So far I’ve hea4d one person say the 8k is about as bright as the 4k WITHOUT the shutter glasses, which coincidentally is roughly as bright as the vive. Okay fine.

I need to know definitively at what rate each eye is blank. If it’s 45 times a second then I’d assume there’s 45 real frames being interpolated to 90, hence the proc3ssing savings-by alternating a blank eye cuts it in half. As long as it atleast feels like a solid 90 fps per eye, but ideally we want that perceived 180fps as advertised as by their brainwarp solution.

I don’t think any of us will know the answers to some of these shutter questions until it is released and tested in controlled environments. I’m sure PiMax wants to keep things secret for now. If you have problems taking a small risk then wait for the full release before purchasing. No matter how it is done it will be at least as good as the 4k and far better than what is available now.

Norm will give the best comparison on brightness. He’s used both the Rift and Vive a million times

Also Pimax confirm in this thread they are still prototyping the displays. The final product may be improved

@Sjef @Heliosurge

Xunshu said the “lenses” are are adjustable. Im sure the oculus slides the whole optical block lense and display for IPD adjustment. Not sure if she ment just the lenses specifically but I hope it’s not a half attempt for hardware IPD

Good point, best would be if the whole block including the display panels would slide indeed. If it’s just the lenses then it still would need software IPD adjustment too. Plus that we’d ‘lose’ pixels for the software IPD, so less image fidelity.

First of all its a logical conclusion, if there would be shutter glass reviewer would definitely notice hard degradation in colors and brightness, since he is comparing it with 4k version with NO shutter glass, remember? Makes sense for me.

And of course thats what he said and they said:

So pimax devs said there is no shutter glass in current prototype and this prototype has little to no ghosting, therefore i see no reason too add shutter glass (which reduces the picture quality significantly in order to decrease ghosting) to the consumer version.
