Hi There, Whether this configuration has been and still is working perfectly well for my all the content of my plex / unraid server since a bit more than a year now, leveraging my intel UHD630 integrated GPU from my Intel Coffee Lake Core i5-9600K for transcoding 1080p flawlessly to whatever needed. Now it seems that 4K transcode with tone mapping is (at least) available from Plex and it can leverage Coffee Lake or newer GPU assist to make it happening: https://support.plex.tv/art
