Hello,
With new top level TVs that are able to handle 4K HEVC 10bit and HDR films, it could be really great if PLEX (at least PLEX Media Player) was able to play them in 10bit with HDR metadata.
Currently PLEX is handling 4K HEVC 8bit only.
Definitely something I would like to see considered. nVidia shield TV is another prime candidate.
No idea how much work is involved though.
HDR support in Plex is what I’m waiting for before I upgrade my HTPC to support 4K output. I don’t want to have to upgrade again, and I’d prefer not to have my HTPC to act as only the media transcoder and be forced to use something like a Roku for the same TV that I have my HTPC hooked up to just to get HDR content.
And if “handle 4K HEVC 10-bit” included being able to efficiently transcode it on-the-fly to non-4K devices.
+1 for this feature. PS4 Pro, XBox & NVidia Shield have the hardware for this. Some Macs as well.
I’d definitely love to see this implemented soon. I’m about to get my hands on a Shield TV in the hopes that it will be able to play and transcode h265 10bit 4K. It should have the grunt for it, I’m less bothered about transcoding of them tbh.

It does currently using SPMC (providing you disable refresh rate switching within SPMC). Edit: so will plex but Plex doesn’t pass the HDR metadata so HDR won’t work.
@georgejolliffe
Do you mean that SPMC is passing the HDR metadata to the TV correctly?
I guess this is SPMC on the Nvidia Shield TV only that can do that, correct?
Having just bought a 4K HDR TV, to not be able to watch ANY of my 4K content as it’s all 10-bit HEVC is such a disappointment. Some of it is also in 23.987 fps (24fps) which too would be a factor, and it’s all in mkv containers.
Basically, everything about them is wrong for Plex, but right for my library.
Sadly my little Mac Mini can’t transcode the video, it’s not powerful enough. Worst still, re-encoding any of it would take days on the hardware I have, so that’s out of the question too.
Such a shame 
@MaGNeTiX What type of TV did you buy? I ask that because I have an LG 65C6P and I can direct play x265 10bit to it… The thing is, I can only do it through a third party application called XPLAY (Well used… PMS 1.3 broke it and the developer has the fix but is a holding patter because LG needs all devs to update their apps for WEBOS 3.5… I digress). PLEX the server can serve of the media via direct play… It comes down to the PLEX client that receives the media… and in LG’s PLEX app it totally craps the bed in that area… and its not a priority of PLEX… So if you have an LG tv… then def get XPLAY… if its a difffernt TV… like Samsung… then yea… you will be limited to 8 bit… and PLEX has no concern about that because they will say it effects a small portion of the users…

Thanks for the heads up. It is (another) LG I’ve just bought (last one was just before WebOS), so will give it a try (when the issues are fixed with PMS!)
@MaGNeTiX Try to connect to PLEX service as a DLNA server… Just go into your sever settings and give those permissions and then connect to the server through the “Video pictures music” app built in on the TV… You can def direct play all 4K 10 bit through there.

Sorry I missed this.
Yes SPMC will pass HDR metadata on the Shield, i’ve not tried other hardware with Kodi.
One must disable refresh rate switching inside SPMC for HDR to work because the shield can only do HDR (and 10 Bit) at 60Hz at this time.
SPMC with the latest Kodi plugin from Plex is my new favorite client. (Sorry for going of topic, i’ll stop now).
When will PLEX will start investigating on HDR support for PMP?
I’m getting my new LG C7P TV on Wednesday and paid for the “Lifetime” subscription with plex, because I’ve used the free version for years. I was sad to know that HDR content is not supported, when will this software update arrive?
Yes it would be great if PLEX staff starts working on this. I have to admin that I don’t know how many work it requires but I think it would be a great improvement.
For the moment, on Windows 10 (with creator update that brings HDR), you can play HDR files with the default windows media player or with PowerDVD17, but not with PMP.
maybe it is possible to write an script. That one programm regonize 10bithdr, the windows desktop switch to hdr mode.
Kodi+dsplayer with madvr support this very well
Early 2021 clean-up: implemented (playback devices are however still limited in the exact capabilities to play certain combinations of HEVC 10bit and HDR media)
