Never mind on the above post - I read that there is an issue with Tonemapping atm and it apparently effects also the AMD iGPUs. At Plex this is being worked at, we'll just have to wait. I'll still setup the Asrock with intel as a second test Plex Server to see how that one handles. When I switch off Tonemapping it decodes perfectly with HW and plays back without hickkups. But, colours are very fainted of course. For those insterested, here's the link to the Plex issue/discussion: https://forums.plex.tv/t/hw-transcoding-with-hdr-tone-mapping-not-working-hw-works-without-tone-mapping-enabled/852524/204

Interesting that it all works...my experience is a bit different, but maybe I've not followed all the steps correctly. I have a Minisforum UM480XT with AMD Ryzen 7 4800H processor. It runs unraid with a few docker containers (Overseerr, Radarr, Sonarr, SABnzb, etc) and of course Plex. I have Plex Pass and enabled the hardware decoding. When I play a movie on my iPad and purposely downgrade from the 4K to 1080p, the movie stutters every 20sec for about 5sec. When I check the activity in Plex Server, it's states its 'buffering'. Processer hits 40-60% which tells me the real transcoding is still (partly?) done on the CPU, although it shows 'transcoding (hw)'. I have asked a friend who has an Asrock NUC (intel CPU 1165G7) and there it playes even without Hardware decoding perfectly on the ipad (from 4k to 1080p). I have the same NUC but it currently runs my Home Assistant instance, so I'm going to swap the two. But before I do, does anyone has any tips for checking in Plex Server if it uses the iGPU correctly?
