I have a few different HVEC files with BT2020 HDR encoding, but they all look super washed out when I play them back on either the XBox One S Plex client or even the standard plex web player on my PC. My Plex Server is a Windows 10 PC i5 with 16GB Ram.
Examples of file types getting washed out colors are…
Hi, sorry i don’t have an answer for you but this is something I’m interested in as well. Were the files being direct played or were they transcoded? When playing does your TV recognize that they are HDR content?
This question is more about playback of HDR files on regular 8-Bit TVs. Half the TVs in my house are 4K HDR, the other half are regular 8-Bit 1080p screens, so I need to be able to transcode the HDR to SDR for the older devices.
I’m also seeing the same thing. Anytime my HDR files get transcoded (for remote viewing, device that can’t do HDR, etc.) the colors are very washed out compared to the the equivalent SDR version (ripped from blu-ray rather than UHD blu-ray). I find it interesting that playing these files locally on an SDR monitor, I get the same problem using MPC-HC or VLC, but PowerDVD 17 is fine. Also working correctly: Direct Stream (of the video, the audio was transcoded) to a Shield that then is connected to a 1080p SDR TV. It seems like Plex’s transcoder is just not properly down-converting from 10-bit to 8-bit. I’m not an expert on color encoding, but it feels like it’s doing some sort of clipping rather than proper dithering. In the meantime, I’ve resorted to keeping both SDR and HDR versions of files (also partly until hardware transcoding supports HEVC 10-bit decode; software transcoding 55Mbps 4k HDR is pretty brutal, even on a Kaby Like i7 7700k).
Hallo VLC Player also does this, I noticed that with 4k UHD / HDR files and so on.
MPC - Best Edition however works fine, can admins look into the issue, I can show you an example of how it looks in VLC player which is the same exact look on plex, compared to MPC - BE(Best Edition)
Now this example is with 1080p from 4k source.
Look how MPC BE treats it very well.
VLC is just awfull and so is plex.

Keeping a second copy is also what I need to do, which sucks because I was originally going to keep 4k HDR copies, then use the Optimize feature to produce a mobile version to save space, but now I have to grab a . 4k and 1080p version, and then let my server transcode the 1080p to whatever resolution. Hopefully this gets fixed soon…I’d pay for another plex pass or donate if this got fixed sooner rather than later. you listening Plex?
vote please for this to solve Tone mapping
