Hi guys, as you may know, Pimax 8K VR will be join the CES show and there are some questions for these who have not used Pimax product yet, come here to back Pimax up if you want, thanks.
Back Pimax here:
Question 1,
Is that a true 4K display?
Question 2,
Is that clarity or not?
Question 3,
What’s your computer config to power Pimax 4K?

1_ It will be a true 4K display.
2_ It depends of the signal.
It seems that Steam locks the signal resolution to htc and oculus resolution for the moment.

If you fool SteamVR to make it think the HMD is and HTC VIVE, is normal that it locks the resolutión to the one of the HTC VIVE.
Pimax is supposed to work with VALVE in defining a new HMD en SteamVR, as OSVR did …
The HTC and the Oculus are just displays like your monitor.
When you connect your monitor to your PC you don’t have to fool something in order to use the max resolution of your screen with your steam games.
It does not work like that in VR which is not normal.
Take Project Cars for example.
If i get a 4K monitor i will be able to set a 4K resolution into Project Cars and get it on my screen.
Same game in VR mode. The resolution you set in game is only used for your monitor (though with VSR and DSR the ratio is affected) not for the headset resolution.
By the way “Pimax 8K” categorie is available now.
Keep in mind that 2x a 4k screen is NOT the same as 8k resolution. If you put 2 4k screens next to each other, the total resolution will be 7680 * 2160. This is half of 8k resolution (which is 7680×4320).
Also regarding the ‘clarity’, I think that’s the biggest problem here. It will only be clear if you supply it with 7680*2160 (or even higher, like 8k) input. I don’t think there’s any such content at the moment. Maybe if they can unlock that resolution for Steam that it would make sense. But if not, then the resulting image will not be as clear as our 4k headset running 4k input (which it hopefully soon can). So in that case you’ll have higher FOV but at the cost of lower clarity.
Nevertheless I think it’s awesome that a company like Pimax is pushing the VR field with technology like this. Hopefully the content will follow.
It’s quite simple when you figured how the 200° FOV is achieved.
What you will have is 4k max resolution for each eye, nothing more.
Then each eye will see a different picture with cross regions in the center of the image which means left for the right image/eye and right for the left image/eye will be common.
I don’t think that is necessarily true. The PIMAX 4K screen has 1920 x 2160 per eye. The PIMAX 8K should be 3840 x 2160 per eye. Even with 4K input some content should look a lot better if nothing else in the data path to the two screens limits it. Also, there is already some 6K content and more and higher is on the way with the introduction of better and more economical cameras.
Look at it this way: the screensize per eye will be larger (this is what’s yielding the high POV). In fact I’m guessing they’ll just use 2 of the same LCD screens that we’re using now. So if you’re feeding that bigger screen the same amount of input pixels, those pixels have to be stretched out over a much bigger screen. Hence the result will be lower clarity. UNLESS of course you use higher resolution input.
IMO pixels don’t have to be stretched.
You will have the same oversampling process if the resolution does not match the source signal. That’s what you call stretch?
Yes. The ‘missing info’ is just being calculated. That never gives the same clarity as original data. If you play a 480p movie on your 75" 4k TV, the resulting clarity will be nowhere as good as playing a 4k movie on that TV.
Sure it’s the same issue than with the Pimax 4k but the FOV will be greater.
By the way they said that they have found a way to get higher resolution from steam.
Sure, our engeers figure out the solution by the support from Nividia and AMD. Then we managed to unlock the resolution limition in steam VR and oculus HOME. Internal test show it works well with all steam VR games, as well as all Oculus games. I can say big image quality improvement was achieved when set the direct mode in 2560*2440. the screen looks more clearer and sharper.
But the original pimax has way less pixels to feed. In fact if you play a 4k movie on the pimax in 4k mode (which it hopefully can soon), then every pixel has its original data, no calculations are needed. If you have double the amount of pixels (in the new version), but not double the amount of input data, then the missing data needs to be calculated.
So, the PPI is going to be the same, but half of the data is missing if you just send it a 4k input signal, so the other half is calculated, resulting in a less shaper image.
Yes, if they find a way to get Stream to work with 7680 * 2160 and you have a fast enough computer to get that in 60 hz, then it will start to become interesting 
No being able to get 1440p out of steam games will be enough (not perfect) and upsampling will help for aliasing.
If you play a 4K movie on the Pimax 4K you will have to downsample to 2K the image because you only have half of the screen for one eye.
But feeding 1440p into their new headset will result in way lower clarity.
Ok but who does that. I want a VR experience so I want SBS 4k movies. No downsampling there. Neither for games.
I see what you mean, you will have upsampling 1440p to 4K which is always great for aliasing.
You should not take them for fool.
The 8k version is announced when they are able to get 1440p out of steam. I don’t think it’s hasard.
For me it looks perfect.
SBS 4K movies should be doable with the 8K version.
