S10+ HDR Video Playback Issues! - Samsung Galaxy S10+ Questions & Answers

So I recently downloaded a few 4k HDR movies, I played them through Samsung Video Player, VLC, MX Player Pro and upon playing them they all looked pretty washed out and off. It was maddening because this phone technically has the best smartphone display, so i looked further into it.
I tried out various settings and video players but none seemed to work. Then i switched the display profile from Vivid to Natural and turned off video enhancer and rebooted. It finally worked BUT only in the original aspect ratio, changing the aspect ratio or zooming in again washed out the colors. Can somebody please help me out!

HDMI mirroring on atrix / gingerblur / 2.2.2 question / 1080p avi's

When I redirected my the output last night to my Sony Bravia, the dimensions on the screen were very thin/vertical, sort of like the phone. Is there any way to make it conform to true full screen / 1080p resolution? or is that just not possible?
What about if I have a high quality movie playing, ie: 1080p divx avi on the phone, and i want to mirror the output to the tv, to take advantage of the full screen 1080p bravia, and not that small smegment everything is chopped down to?
is any of this possible?

[Q] YouTube not playing 720p

Recently, YouTube has stopped playing videos at 720p or above on my 10.1in tablet. I'm not having this problem on my phone, so I don't think it's the app. Basically, I'll hear sound, but the screen will be black. If I drop the quality to 480, it works fine. Anyone else seeing this issue?

Blank camera video playback in every app.

No matter what app I use, I cannot get videos to play properly that I've recorded with the Camera. I can hear audio, but video remains black/blank. I've tried Photos (the stock choice), VLC, Focus, and MiXplorer. None of them can do it. Focus at least shows the first frame of the video but nothing else except audio.
Has anyone else run into this?

terrible screencast quality - screen casting not optimised for this device error -

I have Chromecast set up on my Sony TV. I regularly cast screen from my Moto x, picture quality is superb.
On my new 6t, upon connection of the screen casting, I get a toast that says "screen casting not optimized for this device.". . I can see my phone screen on the TV but it looks very pixelated and just general awful quality - nowhere near acceptable.
Has anyone else had this issue and if not, what method do you use for screen casting? My TV also supports Miracast which is screen mirroring(the 'enable wireless display' option under cast menu) and that fails to connect whatsoever with this device (6t).
Any input would be much appreciated, thank you
&Mod please move to q&a if you can. Accidentally posted in wrong section
I don't have any issues and I cast everything. I have a TMO 6t and I don't have regular cable. It could be an issue with your app? Have you been tied uninstalling and reinstalling? Make sure you are using the official Google app for screen mirroring. It works a lot better than other apps out there
I'm not using an app .I'm using the cast option under connection settings..
Yeah. This is something that has been bugging me since I noticed it a week or so ago. I have a Vizio 4k TV with a Chromecast built in. When I cast the screen of my 6t using the Cast button in Quick Settings, my TV reports it's only receiving a 720p signal. If I cast from YouTube Vanced, Netflix, HBO Go, the TV will report 1080p. If I cast a game from the NHL or MLB app those too are only 720p, although they do appear to be higher quality. However what bugs me the most is when I try to view photos or video taken with the phone's camera. I took some video at 1080p/60fps and when I cast it to the TV using Google Photos it will only cast at 720p and the video looks horrible. Same with pictures.
I tried VLC and it would cast in 1080p but 60fps video was really choppy. Also, if the video is recorded in portrait, it's rotated to landscape on the tv.
I tried AllCast and it cast in 1080p and was smooth with 60fps video. However, it doesn't handle videos in portrait properly either.
Any recommendations for an app that can handle casting local files at it's full resolution that also handles portrait video properly?
I tried it after seeing you having problems, but it works fine for me. It's not as smooth as regular casting (as in streaming via Chromecast, rather than screen mirroring) but there's not much in it. I wasn't expecting much, to be honest, so I was pleasantly surprised.
Hmm interesting..well thank you for the input
My new Oneplus 8pro China 11In2020 build has problem too. Cast quality very poor. What to do? My recent Poco F1 was top notch with little delay. But 8 pro, I did not expect.

Horrible image when playing videos, dark scenes.

Hi, I have a picture quality issue when playing Netflix. I also include links to the video. The image is horrible in dark scenes. It is dark and looks like a mosaic.
The paradox is that if I set the quality in Netflix settings to low, the image looks much better and brighter than with High Quality.
I tried turning the Brightness Boost feature on and off in HDR (new setings in A12), but no change. When turned on, it seems to me that there is more mosaic.
I also tried deleting the data in the Netflix application, it didn't help.
I have an OP8 Pro 256GB, A12, with no ROOT, no other intervention.
The mobile was upgraded to A12, reset factors, and then started installing applications and setting up.
I have the highest quality set in Netflix, max data allowed. The cell phone is set to 1080p and 120Hz.
Is it possible that HDR broke? HDR image create software or a physical component on the motherboard? I can't handle it.
I tried to compare it with my brother's OP8pro, but he has an L3. HDR doesn't even turn it on and it plays in SD quality. I have L1. My brother doesn't care. I also attach a video as I compared. That's the brightness I have when I set the LOW quality.
I tried to play DUNA on HBO Max on my and my brother's and it looked good as well as my brother's mobile.
I add another finding. This problem is not only with Netflix, but also with normal playback. I tried to release a 22GB qHD movie and also in the dark scenes a horrible mosaic in the shadows. I tried to play through the gallery, xPlayer, VLC and the same. When I make a printscreen, and I send it to the PC, the photo is like it is played by the PC (okay). So only the mobile phone has a problem. Interestingly, there is no such problem with HBO Max. I often watch movies, series on mobile. It's starting to bother me a lot, and I'm thinking of throwing it at a service station.
Turn off DC dimming.
and where do you have dc dimming options in oos12 ??
I tried this tutorial but it didn't work.

I'm not sure if it's been removed in OOS12, but you can try searching in the settings. I'm using a custom ROM right now, and my menu layout is different than OOS12, but I'm pretty sure you have an option like that in OOS11.
You might need to enable Developer Options to be able to find it.
DC dimming uses a different technique to control the brightness of the display panel at low levels. It basically turns the pixels off if the value would be close to black. This increases battery life slightly, but you lose some detail in dark scenes in movies and such.

You're wrong. It's not about DC dimming. On android 12 aosp there is also a problem with displaying HDR content the same as on oos12. I know because today I was flashing derpfest and there was also a problem with Netflix. There is no problem on oos11
