Two questions about 8K

Right. thanks for that. The real question now for us 8K X backers is will the give any more information on the unit before kickstarter closes. We need confirmation on scaling!!

Hopefully they will have a better idea once their dp1.4 prototype is functional

It seems to me likely that the final 8k X will scale because why would PiMax sell a headset that will be useless without having to re-write all of the available software? that would completely defeat the purpose. Perhaps they do not yet have the means to upscale since the finalized chip has not become available yet. So far, they have addressed every concern users and reviews have presented. I feel confident that they want to become the Best Headset maker yet.

Games developers donā€™t need to rewrite any coding, any modern game is capable of rendering at differents screen resolutions, they just ask to direct X what is the current screen resolution. It is the same as when you open the graphics options in any game and change the resolution, they donā€™t write an option for every possible resolution they just ask for the list of available resolutions. The only thing different here will be that the game will ask to SteamVR for the resolution and that SteamVR will return the native resolution or whatever they decide. I am more worry about the changes that all the games will need to do to support 200 FOV.

@Sjef is correct though on resolution of textures. But games like Sleeping Dogs have released hi res texture packs. Even Doom 3 had hi res texture packs as well.

The problem is not that it wonā€™t work on the 8k X. It will work. The problem is that without highres content you wonā€™t see much difference between the 8k and the 8k X.

Imagine a 640x480 photo. Will it look much better on a 4k monitor instead of a 1080p monitor ? It will look pretty much the same. Of course thatā€™s not the whole story, because a game of course scales much better than an external hardware scaler, so there will always be some form of improvement. Yet to reallly appreciate the difference between the 8k and the 8k X youā€™ll need content with highres textures (or in the photo example: youā€™d need an 4k photo to really appreciate the 4k monitor)

With Samsung entering a 1600p headset surely steam and game developers will have to start supporting all these new custom resolutions

Excellent post guys. With the 8K unit and Piplay in Video mode (extended mode), what would be the resolution with 2 panels ?? 5120 x 1440 or 2560 x 1440?? Now, if I apply DSR (4X factor) , I would get; 10240 x 2880 or 5120 x 2880??? :fearful:

Hey we already told you games render at the headsets requested res. Lol

@Sjef can you expand on this.

Even in Duke Nukem 3D, which uses sprites in its 3D graphics much like Doom, Descent and Star Ocean: the Second Story, higher resolution means you can make out the details of a character at some distance rather than just a moving blur. Close up it just makes it less jaggy but just as texelated (it also improves depth detail as it can represent more precise angles). Iā€™d understand the reluctance to accept this if the 1440 pixels over 120 degrees youā€™re comparing it to was a high resolution, but it isnā€™t. Itā€™s just not as frustratingly low as the current contenders.

The photo analogy does apply to the upscaling of the 8K model.

Nice one, thatā€™s indeed an advantage too, a bit more detail in the distance since less scaling down needs to be done.

Tbh Iā€™m interested what you think the difference will be 8K vs 8K X in virtual desktop.

I love to use that app and itā€™s the main reason Iā€™m getting the 8K X.

Well on the 8K it will be the same quality as on the 4k. Itā€™s quite sharp but really not even as sharp as an 1080p monitor. Text is pretty readable but still looks a bit fuzzy. I think this is where the 8k X will really shine.

Iā€™m so used to my 4K monitor I canā€™t deal with 1080p.

I love virtual desktop but using the Pimax BE kinda limits me.

Do you have any experience? where is your full review?

Review of what? Virtual desktop on the 4k?

8k or 8k X. nobody knows anything about the X yet. it hasnā€™t been created yet. None of the reviews Iā€™ve seen (iā€™ve seen all of the available ones) say anything indicating blurriness in the 8k. Quite contrarily, they nearly all say SDE and Clarity are the Big Plus. I too have a 4k and a BE and a vive. if the 8k is better than the 4k which is what has been stated due to clpl displays, then I am confident the visuals will be top notch. @generic, I use Virtual desktop all the time with my 4k and although not perfect I have had no issues whatsoever reading any text in it or any other visual artifacts. I would disagree that it looks like a 1080p display I have that too and in my opinion, the 4k far surpasses it. especially in moving images. Truthfully, with static images, you can see some faint zigzag if you really try. I think that is because of the pentile led arrangement. You wonā€™t find anything better than it until the 8k comes out. By the way, I too have pre ordered the 8k X simply because I want the cutting edge tech. and am willing to invest in better GPUs to have that.

You must have missed this one:

"I donā€™t think itā€™s a viable monitor replacement yet, but I think itā€™s totally usable for some light web browsing, IMing, and reading and responding to emails."

https://www.reddit.com/r/Vive/comments/74omua/i_got_to_demo_the_pimax_5k_and_8k_headsets_heres/

Thatā€™s exactly my point. Itā€™s really not as good even as an 1080p monitor. If you think it is you must have a really horrible monitor.

Hereā€™s an actual image from the pimax 4k HMD, exactly as SteamVR sends it out to the HMD:

Setting 110 degrees FoV (download org image via the link).

ā€œCLPLā€ is a word invented by Pimax. Itā€™s just ā€œLow persistenceā€ LCD. The image might be a bit brighter and a bit more contrast but itā€™s not going to bring much difference in terms of readability of text in virtual desktop.

But since the 8k X doesnā€™t have to sample down to 1440p the result in Virtual Desktop should be way better. Remember that you are not looking at an exact copy of your desktop but a rendered version which gets distortion correction afterwards. These 2 ā€˜resamplingā€™ steps will always degrade quality and if you have to sample down to 1440p then thatā€™s going to negatively impact the result for sure. Thatā€™s why I think Pimax 8k X will excel here.

Agreed tge 8k-X will have a better effect for Virtual Desktop. The base 8k though should look better than the 4k Model though as it is 2560x1440/eye upscaled to 3860x2160/eye opposed to a single 4k panel shared by both eyes.

@jimh54 consider text on a 720p resolution on a 1080p monitor. Then switch to 1080p resolution; the text will look overal better.
