Hi all, so I bought 4k HDR monitor for my PC and I wanted to stream some HDR content from my plex server. When I first fired it up and played some HDR content via Plex HTPC it worked perfectly fine, with almost 0 CPU load on my server fast scrubbing on the timeline, etc. After that, I turned off my …

When you went away, did you turn off the computer or walked away and left it running? If the latter, did the monitors go to sleep? It’s possible when they woke up, the hdmi handshake with your computer didn’t work well so your computer doesn’t know they are HDR capable. Try turning the monitor of…

When I left I turned off both my PC and monitor as well as my plex linux server. I already tried restarting PC as well as the monitor but without any luck. I’m using displayport with DSC (without DSC same problem).

HDR enabled/disabled in Windows has no effect on whether the server will transcode or not. Usually a client getting a transcode when it wasn’t before is due to the connection method. Likely your client is connecting to the server over the WAN or proxy connections instead of the LAN. You should ch…

Okey, I tell you due we have a problem. When I booted my PC today HDR was ENABLED! So Plex is messing around.

Ok, so I disabled remote access to avoid going through WAN (even tho I have 1Gb/s upload so I should be able to push max quality), but even that didn’t help, however, I started messing around with the network so my plex server is in a different local subnet than my computer and phone, and suddenly w…
