4K Display on phones Must not be underestimated! All you can do with 4k Vr! - Note 7 Guides, News, & Discussion

I Already started another thread trying to explain why imo a 4K Display is crucial for the future of VR and why the Galaxy Note 8 should keep its promise to include a 4K Display. (Link under Post Scriptum).
---- Then I realize that most people think that VR is just a gimmick and doesn't have its uses. Most users just picked up VR for 10 minutes, liked it and then forget about it. This would have been a completely different if that Display was 4K.
In this thread I will try to explain things that can be done with VR and thus show how these experiences would improve drastically with a 4K VR Display on your phone. This thread will aim to inform people who are not that familiar with technology and especially with VR, but still may be curious of what it can do.
1. Pocket Movie Theatre with true 3D Experience:
You remember when 3D tvs were "in"? And that period of time when movie companies started to release all their content in 3D for movie theatres. Well, there's a reason why 3D stood strong in Movie Theaters since then and not in the living room's Tv. The reason is simple. Movie theaters offer a "Focused" experience with a huge Screen, while the living room is more casual and most common 3D tv screen panels can't compete with the silver screen. VR can.
Most VR users only focus on 360 videos for VR or 3D-360 videos, but they mostly forget about an important alternative: Watching 3D Movies in a Virtual movie theater!
When I used the Gear VR with my Note 7, I was amazed how the experience of being in a Movie Theater was Vivid! BUT Don't get me wrong! Usually I hate watching 3D movies in movie theaters. It's dark, blurry, I hate it. And I hated it on my Asus laptop with a 3D Screen. Again, too dark. But when I tried to watch a 3D movie on the Gear VR, I truly liked it. I thought "now this is how 3D is supposed to be. VR is the gateway to true 3D". The "3D" experience makes sense only in VR. That's what you understand as soon as you try it.
Here's a link that can be helpful if you are interested: https://www.vrheads.com/how-watch-3d-movies-your-gear-vr
But still, something was missing. It was all there, but not quiet yet. I could still see individual pixels. This is called the "Screen-Door effect". Basically it means being able to differentiate pixels on the display. One thing was then obvious. The Display resolution of the Note 7 was not bad at all. But double it, and you'd have a better experience without the Screen Door Effect. 2K is not there yet. It gives you an idea what VR could be, but also states that "4K" is the resolution to start VR.
Here are some live examples on what I am talking about:
Here's a PC Game shot "Zoomed" and "Through its Lens" with the Occulus rift which renders around "2160 x 1200" resolution:
https://www.youtube.com/watch?v=-3yDMgiqqjI&index=7&list=PLVIzBp5A6H0pY5vktvnZomrUUK1de8zD9
Now, the exact same game, again shot "Zoomed" and "Through its Lens" with the Pimax 4K which offers 4K resolution:
https://www.youtube.com/watch?v=SlB5sCbezQM&index=6&list=PLVIzBp5A6H0pY5vktvnZomrUUK1de8zD9
Now you can easily imagine that when not zoomed you would hardly see any pixels on the Pimax 4K.
This shows how a 4K Display is the Milestone for VR. It's THE Resolution that once achieved, truly offers a decent VR experience all can embrace. Is it the ultimate? Of course not. 8K will be better, at 16k we won't see any pixels even when zooming etc... But 4K, even not the ultimate resolution that VR must reach to be perfect, is THE resolution that will validate VR and allow it to be mainstream. VR Should have started at 4K. It's safe to think that starting VR at 2K is premature and stained its capabilities.
With all that in mind, now maybe you could imagine an immersive 3D movie experience right in your pocket thanks to a 4K Display. And no movie theater or home tv system would even come close to compete with that experience.

2. Virtual Desktop
You already know how much technology tries to shrink the size of computing. And based on the past, everyone accepts that the future is "Stronger tech in smaller package". With the Snapdragon 835, smartphones now take a bolder step toward pc level computing. And one of the first steps came with Samsung's Dex. To come to my point, let's first see what Samsung achieved with Dex.
The Dex is simply a dock connected to a monitor in which when you insert your Galaxsy S8, it changes the basic android interface to a PC like interface and transmits the changed pc like interface to the monitor it is connect to, for a PC Like experience. A mouse and keyboard connected to the phone thanks to bluetooth are the last peripherals that allows a full "pc like" usage.
Link for more info about the Dex: https://www.theverge.com/2017/3/29/15104600/samsung-dex-galaxy-s8-dock-announced-price-release-date
My Point is, you don't need that. You can use your Gear VR as a monitor for your Phone. Many apps allow that. But wait. That's not all. There's more.
What if I told you that you could use a true Full Featured PC with Intel and Nvidia level performance on your phone already. And you could use your Gear VR as the biggest monitor ever. Yes, this is possible thanks to a new streaming service called "Liquidsky". This service offers you a "Streamed PC" available to you anywhere you go. Your Steam account, or Ubisoft account any other gaming account including your game library and any other Desktop application you like can be used thanks to this PC streaming service.
What this allows you to do is incredible. You truly don't need a laptop anymore. Just your phone and you're done. The streaming service uses its own server to compute and process your games and your interaction with the minimum latency, and streams you the screen which you can watch on your phone's display. Since the service also supports VR, you can actually play your game on a huge VR Screen, bigger than any gaming monitor. Imagine playing your game on a Movie Theater. Yes. GTA 5 on a movie theater. Knowing that 2K is less than decent to watch video content, wouldn't you want to have a 4K Display for a total immersion?
On the link above you can watch how to use Liquidsky on Android. In the video you will see that they can play GTA 5 on the smartphone, thanks to their streaming service. And sony has already jumped on the Streaming bandwagon already with their Playstation NOW! Service. It's only a matter of time that it will be available on Android. But IT IS avalaible on PC. Which again, you could use Liquidsky to stream Playstation NOW, and there you have it. PS3 games on your smartphone.
Sony Playstation Now: https://www.playstation.com/en-us/explore/playstationnow/
Official Liquidsky website: https://liquidsky.com/
Liquidsky working on Android: https://www.youtube.com/watch?v=1RQXRsrcObo
Any streaming service to come, like the one mentioned above, already is supporting, and will support, VR. So imagine playing your favorite PC or Playstation game thanks to your smartphone, on a gigantic Movie Theater size Screen on VR! With a 2K Display, the experience wouldn't be as neat and clear as a 4K Display. Any display on your smartphone short of 4K Resolution would make the experience "fun but tiring, not quiet there yet". 4K is THE resolution that would truly immerse you and make you forget that you are staring at a Virtual Screen.
3. Exclusive 4K Content for your Phone.
You realize that the two points I mentioned above are not even content directly aiming your smartphone. These are just the "side effects" of evolving smartphone technology toward VR capabilities. But there are so much more you can do just because your phone has a 4K Display. Here are basic VR and non VR features you can do with a 4K Display:
- Watching 4K 3D 360 or 180 degree videos. Way more immersive experience than what the common 2K content offers.
- Youtube's own 4K 3D, 4K 3D 360 Videos. If you think that 4K is niche, you should know that Youtube already jumped into 8K.
Link: https://www.youtube.com/watch?v=RNdHaeBhT9Q
- Able to see 4K Videos and pictures you shot thanks to your device in their native resolution on your smartphone. About that here's a review where Erika tests the 4K Display on Sony's latest flagship, which unfortunately has an LCD screen which is terrible for VR. But still, even as it can't be used for VR, (at least not as effectively as an AMOLED Displays can), Erika reviews the Display and claims that "Yes your eyes are able to see the difference between 2k and 4K".
See it for yourself at the exact time of the Review: https://youtu.be/Hl28F5k20eg?t=536
- And of course the 4K VR gaming content that would soon enter the Android Playstore, as soon as Samsung stands behind the 4K Display.
------------ Bottom Line
4K Display is not just a gimmick. It could open the biggest and the sharpest window to what your phone could show you. It would definitely take off the VR experience drastically. And as I already told in my previous thread, Samsung, or any other phone company, MUST, SHOULD bring a 4K Amoled Display for VR as soon as possible, if they want VR to have a brighter future.
PS: Perviously mentioned Thread Link:
https://forum.xda-developers.com/note-7/how-to/note-8-4k-display-t3622730
Also some mentions and questions how 4K would affect the Battery and the latest Sony 4K display flagship:
- Some worry about the Battery life. Well, this can easily be fixed as sony did on their latest flagship xperia XZ Premium. The phone uses a Full HD display for the everyday use. It initiates 4K when video applications starts. These can be change in options of course.
Same could be done for any 4K Display Smartphone. Just use a normal resolution for casual use, and switch to 4K when using VR, or a video app. Of course, even those settings could be change.
- Talking of the Sony Xperia XZ Premium, it has a 4K LCD Display which creates problems for VR such as motion blurr thus making it hard to use. Yes, it's weird to see Sony bring up a 4K display while totally ignoring VR.
Here's a review of the phone here: https://www.youtube.com/watch?v=Hl28F5k20eg&t

The issue is not creating a 4K display. The issue at hand is creating hardware that can process and render that massive detail onto a 4K display. THAT and that alone is why it started at 2k. Storage is not at par. Internet needs gigabit speeds at the least. And video cards neeed at least 4x improvement. While I agree 4K is a minimum requirement, 4k VR is just not here yet and hardware companies like Nvidia or intel are in no rush to release capable hardware. There’s no profit in rushing

TP Video Record Capabilities?

I, for one, was very impressed by the 'photography' capabilities of the TP recently discussed, but it made me even more curious to know about 'video'. Just ran across a 1080p recording on Youtube. I cannot post the link (too new here), but check the channel for 'ASUSNordicAB'
Video:http://www.youtube.com/watch?v=F_7thh_KUzs
from here: http://forum.xda-developers.com/showpost.php?p=19813697&postcount=13
Yea, just made the 1000 posts full
Though you have mentioned the video over here but still this is quite difficult to determine how would be the actual performance.

I agree that this video is not a perfect test, nor is it one being done by an average guy in his home/yard, but to my (undiscerning) eye, it is very impressive for clarity, frame rate, color, and effects. Since this video was released, here is what some of the other sites are saying:
http://androidcommunity.com/transformer-prime-1080p-camera-gets-a-look-at-segways-and-fashion-models-20111129/
"The 8MP 1080p camera is will also meet or beat just about any tablet out there, and the manufacturer aims to prove it with their latest YouTube video. Compare this with the impressive still images already released....An Asus demonstrator walks around the trade floor showing off the 1080p recording, as well as the standard color filters. Though the Transformer Prime isn’t launching with Ice Cream Sandwich, it will include its own video tools, including an interesting time lapse mode that takes one photo every ten seconds."
http://www.ubergizmo.com/2011/11/asus-transformer-primes-camera-demonstrated/
"Everything is shot in 1080p at 30 FPS (frames per second) and looks extremely sharp not to mention there were no signs of frames dropping. However the tablet wasn’t shooting in difficult conditions so it’s not exactly the best way to judge its capabilities. But for what it’s worth, it does perform well with adequate lighting."
http://news.softpedia.com/news/Asus-Transformer-Prime-Camera-Put-to-the-Test-237339.shtml
"The whole video is shot in 1080p at 30fps and the image looks really crisp (at about the same level as some budget Full HD video cameras we would say) with no signs of frames being dropped. Lighting also wasn't ideal as the video was shot indoors, so this is another plus for the Transformer Prime."
The video definitely seems to look good. I am curious how good the audio that goes with it is though

1440p virtual reality demos

So I just bought a Homido to use with the nexus 6p. It's fun but the resulting image isnt too sharp. I think this is because demo movies are 1080p generally and since our phone is quite big, the resulting image isnt too sharp. I wonder if someone knows a source for 1440p or 4k SBS movies to demo ? I couldnt find any myself. Not youtube but real movies for download, shot in QHD or UHD. Please share if you've found something in this thread, thanks !
Actually I'm starting to think there's currently just *no* SBS content higher than 1080p, even on the torrents I can't find anything higher than 1080p, that's quite a bummer ... Still, if someone knows a demo or something >1080p, please do share !
Actually so it seems the SBS format only goes up to 1080p24 ... Just starting to look into this, but wondering now if there's a format that supports higher resolutions ?
*EDIT* also just found this article, the makers of the Oculus rift say that 8k resolution per eye is needed to truely get rid of pixelation: http://arstechnica.com/gaming/2013/...esolution-per-eye-isnt-enough-for-perfect-vr/ and the article makes a point that you need even a multiple of that to get rid of aliasing.
Oh and 500 fps, hehe.
That seems still quite a few years away, lol.
Currently virtual reality is interesting but I understand now we're still quite a few (probably 10) years away from hardware that can generate a really good VR experience. 1080p24 just isn't it....
To answer my own question:
Full SBS = 3840 x 1080 which exists but requires specialist playback equipment
Half SBS = 1920 x 1080 which is very widespread and also of course broadcast-able.
So Full SBS is actually 1080p *per eye*, so our display cant yield true full SBS unfortunately.

Why the Note 8 MUST have a 4K Display!

Here's the deal!
Samsung is the last chance for VR to really take off. And for that to happen, the only way is to remove, (or at least greatly lessen) the screen door effect which is possible with a 4K Display. This year, VR has to give a serious punch to the market with: New occulus apps, an improved display (4K), and a sensational release such a whole VR movie for all audiences, and a very popular game. And they have to advertise the hell out of it.
That's how they can better compete with the iPhone and cover up a bit the disaster the Note 7 was last year.
-----
But if they don't go the "VR" way what will happen? (meaning no 4K screen, and improvement in their development for VR).
VR won't go any further. Don't count on google or Daydream. Google hits and misses since the Google Glass or any of their new software which come, change name and then disappear. Daydream is out since like what? 1 Year? And no one outside the tech community even have heard about it. Google doesn't have Apple's charisma when launching new products. Talking of Apple's they don't care about VR. They see it as a gimmick and think that it will disappear soon as 3D disappeared from TVs.
Sony just releases a phone with 4K Display but doesn't support VR cause they don't want it to compete with the PlaystationVR, which in its turn doesn't seem to be reliable after the mediocre titles announced for Playstation VR at E3 2017.
On the PC front, VR is completely absent. The HTC Vive and Occulus Rift can't sell. They both flopped hard. Samsung has sold way way more VR units then those two combined.
In fact, Samsung is the leader of the VR market with the Gear VR. Therefore, the fate of VR rests on their shoulder.
----
And that's why if Samsung releases the Note 8 as a Galaxsy S8+ with a Pen, (1440p Display), it will mean that they do not expect VR to take of, and will keep it as a fun gimmick in the side and that's it. And slowly VR will disappear.
As a fan of VR and believing that with the right content and approach, VR is a valuable entertainment and a great asset, especially if you travel a lot, and want to bring your "Home Media" with you anywhere you go.
So it would be a shame for Samsung to release the Note 8 without a 4K Display. A huge let down.
Do you really think they would do that with the Note 8 tho? the times where the Note line got spec update are long gone with the Note 5! They will wait for the S9 with new things like that.

You got a point there. Who knows? But maybe they'd want to experiment with a 4k screen on the Note 8 first as they did with the Iris Scanner which appeared on the Note 7 first. Who knows what samsung is thinking. To tell you the truth, them trying to get a fingerprint scanner under a display is ridiculously pointless imo, but the greater audience seems more focused on these gimmicks instead of way more interesting improvements like Dual speakers for stereo output, or a 4k screen for VR.

Samsung is 100% not going to do any half baked experiments with the Note line anymore after what happened.
I love using the Gear VR for 2D stuff like Browsing looking at photos and watching videos. It does that very good imo. But when it comes to 360° stuff you are right the low resolution kills it. And would love a upgrade. But urself are talking about the greater audience and do you think they care about VR? I don't think so! Most of them don't even know what it is, don't use it or think it'S a gimmick.

To be fair, they are bringing the dual camera to the Note 8 instead of the Galaxy S8+. There goes the theory that the S like is the innovative line. A 4K screen is not a "half baked" feature. Sony did it, Samsung can do it.
But the best anwser would be that 4K would be an option. When using your phone normally for daily tasks, the phone would use a full hd or qhd resolution, and may automatically go to 4K when the phone is used with the Gear VR. So unless a user changes the settings himself, the phone will have a usual resolution.
No one can argue against the fact that to have more options available is better.

VR on the Xperia 1 ??

Hi There XDA friends!
I have recently got my Xperia 1 here in the Netherlands and am really enjoying the Media benefits of the screen. I was wondering if anyone has tried VR with it?
I come from the S8 and have used Gear VR, but the truth is the SDE was always an issue as a distraction especially for movies and Netflix (Oculus APP).
Can someone maybe try a 3rd party VR lens and let me know the quality in terms of SDE, also would appreciate the suggestion for a good 3rd party gear compatible with the width of the Xperia 1. The 643 ppi of the screen coupled with OLED makes for a killer combination.
Sony should have just made a GearVR-ish setup for this and made it compatible with PS4 remote play, a lost opportunity there SONY!!
Thanks in advance and cheers.
Hello, I am interested as well which headset will fit the 21:9 ratio. I have owned Xperia XZ Premium for 2 years and have enjoyed the 4K (807ppi) which I can tell a difference from high end Samsung counterparts. Xperia 1 is less in PPI but it is OLED screen so I wonder quality-wise what would be the difference. Thanks

Hello, I own both Xperia XZ Premium and Xperia 1. From hands on experience, I feel Xperia 1 is better than Xperia XZ Premium when I compared both on the same clip.
Additionally, most 360 videos out there are 4K, 5K or 6K which I don't think would utilized full PPI of Xperia 1 nor Xperia XZ Premium. Those 4K, 5K or 6K resolution means total resolution for entire 360 canvas, so when you view it, the FOV is just a portion of it therefore you are not viewing the entire full 5k or 6K resolution. I am not an expert, but I am thinking it may take something like 12K+ video to fully utilize the phone screen quality...
Hello, I used Noon VR headset to try out VR with Xperia 1. Never ever tried VR before so no comparaison here. But SDE is not disturbing, you see it if you focus on it, I tried to get the photo as it appears, but it's slightly more visible in real life.
But then the main issue is that like 95% of the store app, VR app are not natively in 4k, so a 12K video will get downscaled into a FHD or 2K image by the APP, then upscaled to the 4k screen by the phone. So SDE is good, but quality not so much. But then again, just tried some game and video with the NOON VR app, now I'm waiting for the valve index xD
Also wanted to point out that OLED is not that good for VR since it use a pentile subpixel arrangement, that is less sharp than a true RGB arrangement you will find on LCD panels. That's the reason why Valve went with LCD rather than OLED.
That's also the reason why the 4k screen make sense on the phone, it reduce the blur effect induced by the amoled pentile panels.

Question Is there anybody know how to set global 4K resolution on xperia 1 iv?

I ve tried wm size command but it no longer work since it is Android 12.

I just never see it enable 4K even I m viewing images with gallery app.
So I just want to force it for better experience.

I'm not convinced, if this would be visible. Probably depends on your visual acuity.
Mine is not the best, and for the life of me I can't see the difference between 1440p and 1080p on such a small screen.

There IS it, I ve paid for it, and I WANT it.
And experience will be different for me when viewing large size image in 1:1 scale.
It is just like refresh rate, since there r people cannot get the difference between 120hz and 60hz(or lower). But you cannot just disable higher refresh rate FOREVER just because there r some people cannot distingurish.

It's also to remove unnecessary downscale/upscale when watching a 4k movie. Since most app view the screen as a QHD one, VLC for example, will render a 4k video as a QHD one by downscaling it, then the phone will upscale it back to 4K.
Sure you will probably not see a lot of difference with native 4k as the upscaling technology from Sony is pretty good and you still have the 4K screen resolution giving extra sharpness.
Also, what some people seems to forget, is that the image displayed will always be 4K on this screen, a FHD image will be upscaled to 4K by the phone, and the higher pixel density make it far better than the same FHD content on a QHD screen especially for AMOLED screen that are somewhat blurry on the edge due to the subpixels arrangement.
This being said, you can put the screen in native resolution all the time, just going in the developper option and setting the screen minimal width to 1644pixels to match the 1644*3840 pixel resolution. Doing this, VLC that I tried perfectly render a movie in 4K, but your overall UI is ****ed up and you can barely use the phone. That's not what is wanted. Sony is just boring us for 4 generation with its 4k white list apps. I don't even know what is the recommanded app to watch their 4k HDR spiderman extract.
It's stated that the screen only runs at 4k in certain apps and scenarios, Theres no option to change that.
More accurately: The phone only render graphic at 4k in certain apps and scenarios*
The screen always runs at 4K since it's hardware and number of pixels can't physically be changed. The phone upscale every content to 4K all the time but render some whitelisted app directely in 4K. Still better than proper 2K as the pixels are smaller, but also mean your 4K videos on VLC will be downscaled to 2K by VLC then upscaled back to 4K by the phone, only because Sony didn't whitelist VLC that is perfectly able to run native 4K.
I almost have the same question, but instead of 4K I want to set a global 2K resolution.
4K is way too overkill, but 2K is the best middle ground between display clarity and battery life.
that is what you basically have, 99% of the time your phone won't render 4k. Doing that for all scenarios in which things are rendered in 4k would make absolutely zero sense because then they would need to be upscaled again to fit the 4k reselution
