[Google Pixel 2 XL Questions & Answers] EeZeEpEe:
Just cause I have some time this morning, I'm privately uploading a 4K video I took over the weekend to my YouTube and going to compare it's playback versus casting it.

---------- Post added at 10:13 AM ---------- Previous post was at 10:13 AM ----------

Yeah I have Android TV as well.

---------- Post added at 10:31 AM ---------- Previous post was at 10:13 AM ----------

So my YouTube video played way smoother and sharper than casting it directly off my phone. It was a sunny beach shot and it was especially noticable in the blue sky. Also, this was just the 1080p version as I didn't wait for the 4K processing to finish and become available.

Conclusion:

Android TV with Chromecast built-in does the job to playback recorded videos but don't expect full quality. There's definitely some kind of on the fly compression going on and to be honest, I don't know if a standalone Chromecast Ultra would do any better. I think it's really 4K for the apps that support it like Netflix and Prime Video.
[Google Pixel 2 XL Questions & Answers] Mwoagh:
Casting from Google Photos terrible

I can add to this. Casting from Google Photos on my Pixel 2 to Chromecast Ultra does not give acceptable quality video. There are very annoying artifacts, making it unusable (good quality 720p would be better than this, really!). Casting the same video (after uploading) from Youtube does give the expected 4K quality (needed to wait 10 minutes before the 4K processing was done).

Same problem when casting pictures, the quality is just not good enough. I hope Google will fix casting from Google Photos soon, but from reading on several sites, people have been complaining about this since 2014.

I got help from the above article.

so I am using daydream as 4k / 2k.

1. Use adb to change the resolution to 4k / 2k.

2. Use the attached 4k / 2k qr code.

3. Enable the skip vr entry scene in Day Dream Developer option.

4. Turn off nfc.

5. Use Daydream.

Daydream by pass (release app limits)

https://xdaforums.com/mobile-vr/google-daydream-vr/spoofing-daydream-compatible-device-t3534943

Beyond the sexual and monetary moralism surrounding virtual reality devices, I just want to know the truth.

I think. Xz Premium is the highest visual quality of all virtual reality devices for use with YouTube Vr Platform.

I might be telling a lie. I'm just curious.

4k ips That's great. Video quality.

(Pimax 4K is similar panel)

Low latency could be a problem.

But I had no problem viewing flat screen videos.

I liked the movie watching very much with Xzp.

One could say

the daydream view 2017 fov is narrow..

Netflix vr has a film, Pacific Rim.

Watch this movie. If you use big screen size with Daydream View 2017, you don't understand the movie action scenes. Symbol recognition fov of a human being is 60 degree.

I think..

Daydream View 2017 is great for movie watching..

There are already sufficient viewing fov to watch movies.

I think..

4k ips came close to the experience of looking at PC monitors.

I wonder if I was wrong..

I wonder if people just don't know..

--------------------

Further information...

Oreo rom is good working in 4k/2k vr.

not nougat..

In nougat..

The screen is stained.

Kernel problem?

Sadly, I have no ability.

moonlight for daydream

https://www.reddit.com/r/daydream/comments/877mcp/moonlight_for_daydream_stream_your_pc/

It is an app to stream 'PC screen Itself' with high video quality wirelessly.

'Wireless'

I think...

Netflix vr has a video quality of 500 ~ 600p

With this app,

more than 1080p netflix video contents enjoying is possible.

This app works for only nougat..

Operating in nougat..not oreo.

Sometimes the screen gets stained.

if reboot, ok..

I want to use this app and 4k/2k vr at the same time.

If so, the app should work in Oreo or there should be no spot problem in Nougat.

Can someone solve this problem?

[Sony Xperia XZ Premium Questions & Answers] Miustone:
That's great Man! Thanks for sharing! But the Title... lol

I will share it on My Patch since i just enabled Hard/Software Support for Daydream / VR with the coming Update. Hope it delivers the wished Quality and that the 4K Display switch Option on AOSP soon works again on Oreo...

For now works just the ADB Command.

BR

Edit: Would be interesting how good this works on top of My Patch on AOSP since it has full Support for Daydream and VR (Including Configs, Permissions and Settings + Play Store App Compatibility). Will release it soon and hope somone can test it with a Daydream Headset...
[Sony Xperia XZ Premium Questions & Answers] onkelfeix:
That sounds very interesting - I will test this in the near future.

I don't get the thread title though , but I can say the XZp has a much clearer image than my Oculus Rift or my last phone (Galaxy S6). But it is only really good for using a vr setup that doesn't require to move your head. I use VRTV as my player, not the perfect app but pretty near to perfect, if Daydream will ever work on my XZP again, I'll test DeoVR , which is in my opinion the best player for PC/Oculus and hopefully for android as well
[Sony Xperia XZ Premium Questions & Answers] Miustone:
Awesome to hear from someone who can compare the Quality! I was never a fan of this Headmoving Stuff. SONY HMD was the true sh** when it comes to a great Head Mounted Display Experience and as a Gamer to i still prefer to move the View Field with My Mouse instead of using Sensor. I can just recommend this kind of using even with VR Headsets. Less shaky and a lot more Precisely!

Another Question, Is heat a Problem on Your actual Setup? I can ensure it will be much cooler at all with AOSP and the Patch. Just played a Dungeon Session Shadowgun Ledgens on Ultra Settings with 60FPS and i got almost no heat or Performance Issues. It's incredible how big the difference to Stock is...

I'm also one of the Founders from Riftcat (VRidge), and i can really recommend it btw. I also bought Moonlight but i was never able to use it as HMD (Without Headtracking). It would be Ultra Killer to have a Way to use the XZP as a 4K Head Mounted Display with this two Services. Would be really thankfull for any Ideas (Mainly using the PC for Video and Work, just sold My GTX 1060)!

And a last Thing i have to say after reading Your reply again. The XZP doesn't supports VR with Hardware or Software (But it could) on Stock right!? The funny Thing is, i really enabled full Support for it. You can choose between Flicker Reducing or Sharpness in the Display Settings, and it allows You to setup Daydream on the normal Way. Visit the Play Store, Download the Daydream App (VR main Services are included in the Patch) and set it up. It does also support advanced Daydream Options and it handles the VR Services over advanced profiles which are involving the Hardware and the Software Parts of Android (Full Support). So it should be a huge upgrade compared to Stock. And AOSP has also Options for the Display Resolution / Frequency (Which are not working yet), which could be the perfect addition to that (Switching between Options without ADB).

I would really appreciate to hear from You what You can reach with the Patch and AOSP! Sadly do i not own a Daydream Headset (Just a Chinese Cardboard which collects Dust), or any other Kind of VR Headset so i can't fully test everything. But i think i will go to buy a Daydream 2017 Headset when i have some Money again. Would really like to use My PC on My XZP Screen...

Can't wait to know more about all this! BR :highfive:
[Sony Xperia XZ Premium Questions & Answers] D daydream:
I've always used the vrtv, my best player ^^

It plays on the Sony 4K panel without adb command.

Daydream Skybox app

can also be used with 4K panel using adb command.

I haven't used deo vr,

but I'm looking forward to a great experience.^^

I do not know about PC vr device( Samsung Odyssey was put on for a while, and tracking was great.)

but I think it is okay to flat video watching head tracking. Move less than one expected.

I think smartphone head tracking capability is poor and there may be a problem there. Instead, Xzp video quality is supplementary.

I think

not suitable heavy game.

suitable video watching like youtube vr, casual game, 2d screen game..

I look forward to your response with experience as I can not use a large number of vr equipment.

thanks your reply^^

Carbonrom + snappatch

It doesn't go over daydream vr entry screen.

I can't get to the next step on the controller setup screen.

stock rom v1848. It runs well.

I haven't checked more anything else.

Sony Oreo stock Rom are well run but the screen brightness turns dark during long time using 4K setting vr because of the heat problem.

------------

Daydream View 2017 headset is recommended. It is comfortable-fit, lightweight, and has good fov and very little misting. First of all, It has a 'heat sink'.

https://www.virtual-reality-shop.co.uk/

There is a best-seller baofeng mosing s1.

It is known as the current mobile best fov.

I bought it.

For xzp, size do not fit, so further work is required.

There is a misting. can't use glasses. I think fov is fine but that doesn't get ahead of Daydream view 2017 quality.

Fov is less interested when adjusted.

I eventually use a Daydream view 2017 headset.

Fov small, awkward sense of wearing,

but untouchable video quality is Antvr.

For image quality, sometimes I use antvr.

That's all.

I can give you information now~

Post moved backwards.
[Sony Xperia XZ Premium Questions & Answers] onkelfeix:
Wow, seems that this thread is starting to skyrocket :)

I will take my time and read everything again, currently at work and a bit in a rush....

With my current setup ( g8141, turbo p75d rom , vrtv , bobovr z5 headset with daydream compatible controller, with sitesinvr calibration ) I have no heat issues (my galaxy s6 got so hot after just some minutes , that it would be more safe to wear aramid fibre gloves..... ) and the image is not distorted.

The manual "sharpness setting" the headset is offering seems to end right at the position the image is getting sharper for me, if the phones display is moved 1-2mm further away from the lenses, it might be even better, but not possible.

So maybe this is something that can be dealt with on the software side. (I remember the Oculus, DeoVR software offered a sharpness slider which did magic to some videos.... )

[MENTION=4756773]Miustone[/MENTION]: What I've read about your Snappatch is that you can alter the max bitrate limits etc which the snapdragon835 is able to play? Being able to play higher resolutions than regular 4K would be great as well.

Anyway I'm highly interested in testing this, even though this is completely new for me. Have never been using an aosp rom, has always been a little bit too debloated for me.
[Sony Xperia XZ Premium Questions & Answers] D daydream:
you are right.

From my experience..

In general use, there are no heat problems.

In general use Youtube vr operates at 1080p.

there are no heat problems.

but image is blurry.

In general use Youtube cardboard option, vrtv is 4k working. but youtube vr is not 4k working.

In adb, qr code setup use Youtube vr is 4k working.

Image is sharpness like youtube cardboard.

but heat problem..

In high temperature and sony stock oreo, the screen turns dark brightness automatically. but There is nothing wrong with the performance.

Thank you very much for your courtesy to me.

I just want to share my vr experience about Xzp.

I'm looking forward to your work.

Anywhere in the world, I don't find detailed comparison between 2k oled and 4k ips smartphone vr experience.

All devices is not perfect.

there are good points and bad points

there is a good place to use.

I was curious.

Although good video performance,

xzp can not be mentioned in vr battleground.

there are any advantages to use xzp,

I would like to let it know for people.

Someone may use vr with xzp for the first time

because of this thread.

I'll leave a brief piece of information for xzp users.

It's no big deal. People who are interested and experienced may know.

However,

it is better to avoid the stress of first vr experience.
[Sony Xperia XZ Premium Questions & Answers] onkelfeix:
A real in depth comparison is hard to find. I can just tell from my personal experience with Galaxy S6, Oculus Rift and now XZP.

I'm curious what can be achieved by software / settings with that 4K display the XZP has, but I'm pretty sure that it'll stil be a "high persistance" display overall and is lacking external "correction". If I remember correctly the Daydream headset has no electronics built in, so the phone is completely on it's own and will most likely start to drift away.... thats one big disadvantage to the GearVR for example. Don't know what regular "Daydream Ready" phones do in that case but I think they might have better calibrated sensors, or just have the same drifting problems.

He is not usually interested in smartphone and vr.

I gave my friend youtube 4k vr experience with xzp.

He was very interested in flat screen images quality.(especially music video.)

He showed interest in your work I told him.

He said your work would be valuable.

Surface reactions of people in online are unimportant. Everyone who has experienced with xzp, it already knows it.
