Hi, I will copypaste the thread I did post on reddit.
I've just recently got the S9+ Exynos (EU) variant and I wanted to be hyped about HDR media playing. Downloaded some 10bit HDR H265 files and played them through the Samsung Gallery. Cranked High Performance mode to 1440p, +10 brightness and tried between Adaptive/Cinema Mode (this didn't make any difference besides some slight changes in colour and gamma).
Problem is, I see color gradients and a bad greenish tint, lifeless appearance overall. I did try Youtube 4K HDR demos in 1440p as well and, while I can see the extra PQ, color banding is very apparent: background blurred images seem like a weird crushed rainbow :-/
Is this supposed to look like this? I did read about the release (around march) issues people had with black crush and Netflix's HDR, but also read that some update fixed it. It appears that S9+'s AMOLED is 8bit, so is 10bit HDR and Youtube's HDR the culprit? How to play HDR media properly?
PS: Another thing to note is that neither gallery video player nor in youtube player does say HDR in any window or setting while checking file properties. I did read some reports of people seeing HDR stamped at the start of the videos.
Thanks in advance,

I just recorded a small video of a local event with stock camera app set on 1080p video. In the video if you look around face of the singer or any thin lines, you will see little squares or jagged lines etc., as if the video was upscaled from 480p or something. It's even more visible on original file on a normal PC display, but even in the web version it's a defininte huge loss of resolution. This is very weird. I'm using madsurfer's ROM, but I don't think it's ROM related.
Here's the video: https://goo.gl/photos/c17a5iofhPas73aP9 - first few seconds are out of focus, then you can see the problem.
Any advice?
OK, I have found a workaround for the video problem!
First - I have confirmed, there is definitely a problem with 1080p video recording with stock camera app. I'm not sure if it's ROM related or stock is the same, but it's definitely there. The quality is very very bad, pixelated and feels upscaled.
However when I have installed Cinema FV-5 app, the quality is great, no more pixelation, everything looks better, even crappy digital zoom is smoother. I have shot same video at the same time with stock app and FV-5, and there is a huge difference:
Stock camera app video - pixelated and jagged edges, huge artifacts, digital zoom shows big square artifacts. Check roof edges on top left, and a street lamp pole line.
Cinema Fv-5 video - everything is smooth, no jagged lines, digital zoom shows no squares or pixelation - just sharpness loss.
You have to open both videos on a PC in full screen and with 1080p HD quality to really see the difference.
So the problem is clearly with the stock app, or madsurfer's ROM version of that app or settings. I think another camera app such as FV-5 solves this issue. I liked the simplicity of stock app, but it's not usable at this moment.
Hey anyone facing when playing a hdr video in youtube the color looks washed out
There is no contrast and no accurate colour see screenshot below
I don't think Poco supports HDR video with its "meh" display.
Edit: apparently it should support YouTube HDR playback in 1080p, but I think the screen is not capable of displaying it. I tried some videos and they look washed too.
Same Problem I have

Yup, I have checked for the same and yes colors are washed out tend to be more grey and white side so there is no hdr support in Poco. idk why they still show it in youtube listing like1080pHDR.

yes
this is annoying because if videos are HDR then we cant watch in youtube i didn't find any option to play hdr videos without HDR.
Pause the video in the exact frame, go to display settings, turn off Night/Read Mode and change the Contrast to Increased/Automatic contrast(Warm), reduce the brightness to the viewable range! come back to Youtube, you could see a nice difference in the paused image! shows good dynamic range! but once starts the video, display resets and it starts showing washed out images!! Looks display is ok to display issue in the software to me!
did anyone found how to disable hdr playback in youtube ?

This same video playback on my poco F1 looks like Ur screenshot 1 and def not ugly like the 2nd one.
Unfortunately I am not able to take a screenshot or screenrecord of the same .
The problem is with hdr playback the screenshot comes out black.
Is my display ok cos of the pie based beta 8.11.1 I am using.
Attaching screenshots to explain what is happening with screenshots
Well i played Avengers Infinity war 2160p.10bit.HDR.BluRay.8CH.x265.HEVC (3.69 GB) via both the stock video player and MX player and both rendered colors correctly ?
I can see HDR youtube videos near to the perfection for this screen. The colours are amazing.

I am whit MI 10.2 beta 8.11.1
I found a weird bug. Turn off auto-brightness and increase brightness. Now play an HDR video on youtube. While that washed out video is playing, hower your finger over the light sensor on and off. The screen will try to get dimmer for some reason as if the auto-brightness if on.
I can confirm too. YouTube HDR videos look more on the natural side and a tiny bit washed out. It's definitely doesn't render the more punchy Colors of HDR. Obviously because Poco display is not HDR complaint.
The youtube videos look way better on the web browser than they look on the youtube app.

Well I'm using the global rom but do check the screenshot for the additional details. As for the HDR screenshots, all of them comes out black.
Plays awesome in 8.11.1 beta Android 9 ROM...
Colours look beautiful for me in HDR. When I rotate the screen, it switches back to regular version for a split second and then back to HDR.
Running nitrogen OS on my device.
Check these screenshots
Videos downloaded in HDR format and 1 without hdr
Now you can tell the difference

U mean to say the bottom ones are hdr videos playing on ur phone.
If that is true I certainly don't have such problems.
I have compared YouTube hdr playback on poco with non hdr playback on iPhone 8 plus and mine looked better.
If u can link which videos to download and test i can send screenshots.
the colors looked washed out, because when the phone is at max brightness (which HDR videos turns up the brightness automatically).
there is an option in "display"
"Contrast and colors" select "standard contrast"
pretty sure your issue will be gone, but do note that selecting this option will make your display look yellowish
poco support hdr does it mean i can download hdr content and use it and get the reql hdr in my phone i mean will the viewing experience be real hdr
well it can play hdr files fine with the media player but youtube hdr videos are washed out .. you have to understand the screen is only 8bit not 10bit so if the app will not convert colors correctly form 10 bit to 8 bit it will be washed out
Hello.
I was wondering if some of you found a way to read x265 files with 10bit HDR content bt.2020.
Using the native video app or VLC, I just got a grey-ish screen like I have when watching the movie on my SDR computer screen. The native app didn't even decode the soundtrack (aac I think). Any clue?
I use a mobile version of Kodi, hdr works very well, mxplayer work . Besides I do not have any problem playing hdr on VLC either. Regardles to vlc you may consider turning YUV (FORCES CHROMA) In setting,advanced,
Ps sony Xperia one pick brights is not as high to fulfill full gamet of hdr , although do not qoute me on that
I will try those one, thank you.
I suppose it's about the codec used. I'll try another file

That a files format I use and plays perfect
I tried Kodi and MX player, and run the same as VLC:
SDR:
Video: MPEG4 Video (H264) 1920x808 23.976fps [V: English [eng] (h264 high L4.1, yuv420p, 1920x808) [default]]
Audio: DTS 48000Hz 6ch 1536kbps [A: English [eng] (dts, 48000 Hz, 5.1, 1536 kb/s)]
HDR:
Video: HVC1 1920x804 23.976fps [V: Avengers Infinity War 2018 x265 1080p HDR10 [fre] (hevc main 10, yuv420p10le, 1920x804) [default]]
Audio: DD+ 48000Hz 6ch 512kbps [A: VFF EAC3 7.1 [fre] (eac3, 48000 Hz, 5.1, 512 kb/s) [default]]
HDR content here is really darker. But I was wrong, it's not grey-ish like on my SDR computer monitor. I have to set the brightness at the maximum to watch the HDR movie, and be in the dark. Well, the trailer of spiderman far from home bundled in the phone goes the same way (Video: HVC1 3840x1644 23.976fps 12480kbps [V: video handler (hevc main 10, yuv420p10le, 3840x1644, 12480 kb/s)])… I'm in creator mode, but maybe I messed up other settings?
It's boring, but I'll try a factory reset to be sure.
EDIT: nothing after a factory reset. Maybe I just need to put the briightness at the max for HDR content to have enought output for the light peaks.
Ok, so it was just a misunderstanding from myself. HDR file should be watched with brightness at 100%. It will not use that much Energy since the movie is purposely darker, allowing brightness peak on some part of the screen. Just watched Shazam in full blu-ray iso and it was really great. Beautiful screen. I need a 2To SD card tho xD

After latest update, phone automatically turn brightness to 100% for HDR content. At least this has been consistent with YouTube HDR videos.

I'll see that when I'll get the update. Not really a matter since it's just a swipe on the screen with VLC. Just a shame VLC is not 4k. I have my 4K video downscaled to the app to be read on a 4k screen -_- (proof is if I set the zoom to "centered", the image is twice time bigger than the screen, it should be perfectly displayed if it was 4k on 4k).

I may find a solution for the problem, the sony xperia one is running at 21:9 version of the 1080p which is not really hdr standard, try to turn off the game enhancement , it will switch back to native 21:9 4k it should switch to natively hdr... I have disable that on the very first day of mobile phone usage since I do not game on my phone.

Thanks, but are you sure game enhencer is used even when it's not displaying the game enhancer settings and with app that are not on the game enhancer list?
Anyway, I disabled it and VLC is still in 2K (I never had game enhancer working with this app since it show a big round Rainbow on the corner of the screen when game enhancer is working).
And I'm positive it's 2K and not FHD, the 4k movie are only cut by half. And it's logical since most phone work in 2k so VLC was developped with that in mind. Xperia 1 use the max setting available on an app till 4k.
Anyway, pentile 4k is really crisp and it's ok for me.
About HDR, just set the brithness to maximum to allow the phone to use enought power for bright peak. The rest of the scene is purposely dark because of this.

The screen is not 4k native. It doesn't work that way.
Hello everyone.
The HDR mode in Android devices results in picture quality far worse than a regular HD mode. For instance, as you can see from the screenshots, "Our Planet" in HD mode looks way better than in HDR. The colors in HDR are washed, brightness is way down which results in crushed shadow details. I was demonstrating this at the local BestBuy where the staff was dismayed to see the difference. There is something wrong with that HDR algorithm?
