bump!!
Looks as though I found the answer to why this isn’t working in Windows yet.
It basically boils down to the transcoder being 32bit.
They are working on a 64but version but as always no Eta from plex unfortunately.
Did you ever get this working?
I think it should be possible to get it working, but I stopped trying. I setup a Proxmox server and run Plex in a Linux vm now.
After much searching and trying i’ve given up.
my options are either ;
- move my entire setup to linux
- wait for plex to maybe bring this to windows in 2030

Plex devs need to get to work and do something useful this is ridiculous…give us this feature now
Given up waiting for this…
They haven’t even finished off the Intel iGPU implementation, let alone undertaken this new development.
Migrated my PMS from Windows to UnRAID and have HW HDR to SDR Tone Mapping all working perfectly with a Quadro P2000.
Frankly, running under Linux is far more stable all the way around versus Windows. Since moving from Windows to MacOS (M1) and now to Ubuntu my Plex server has been rock solid no matter what I have thrown at it with an Quadro RTX 4000 doing the heavy lifting.
Can you clarify?
Quicksync on Windows and Linux doesn’t break a sweat with 10 4K HDR remux transcodes with tone mapping from KabyLake onwards.
According to Plex’s support article, they have listed the HW Tone Mapping for Intel on Windows, as ‘PARTIAL (Reduced Performance)’:
The ‘PARTIAL’ flag has been there ever since Tone Mapping was first introduced, however long ago that was.
I’ve not personally tested that combination, as I went down the Nvidia GPU on Linux route, due to the information provided on the above article.

Contemplating this move as we speak.
How was the setup? I’ve played with unraid on a Vm and think I can get around nicely.
Just wondering how easy getting the nvidia transcoding to work was? Which docker plex did you go for?
Also regarding plex metadata, did you manage to get this transferred to? Or did you start fresh
Much easier than I expected to be honest.
I’ve never used Linux before and didn’t have to do anything in the command line, UnRAID is very intuitive and I can’t recommend Spaceinvader One’s videos on YouTube highly enough.
I started from scratch, didn’t bother with transferring metadata, however have read it’s as simple as just SMB sharing the appdata folder, then copy & paste, should you wish to.
I used the official Plex docker image and followed the below video to pass through the Nvidia GPU to the Plex docker:
All worked perfectly first video I tried!
Yikes I finally found this thread after banging my head against this for a while. +1 to the devs, please add this feature in Windows! Powerful CPU and Quadro M2000 handles multiple simultaneous 4k transcodes but flops on its face with SDR tone mapping enabled. As I run this entire system in a Hyper-V server, with discrete GPU passthrough I think it would be a pain to figure that out in Linux.
Hurry up devs get off your ass and fix this
Fix this!
This has been driving me crazy for years now! … PLEX please fix it. Need NVIDIA HW support under windows server.

I agree, i’ve had to run Emby side by side with plex for this reason.
Emby transcodes HDR 4k on windows with no issues with Nvidia GPU.
PLEASEE PLEX

It even sucks for Direct Play in local network setup. Kodi works without issue on Windows. Infuse app on Mac, iPhone and Apple TV 4K works fine using the PLEX library. … But PLEX … lost in the weeds … pretty shameful.
Wtf is the hold up! Plex developers need to get off their ass and fix this now!
