The problem is almost always you didnt purchase the licenced HEVC video extension decoder from microsoft app store for $1
listed by microsoft corp. then play it back using windows photos app or mediaplayer app.
Or you are maybe using incorrect fake player software. since many players are open source they are fake version of source code of a different one. You probably rather stupidly use free codec pack which riddled PC with viruses or install third party overclocking or monitoring software which is NOT part of the amd adrenaline software or ryzen master.
You should if you have multiple monitors set them to the same refresh rate and ensure you are not exceeding the bandwidth of your display cable, or the ports of your hardware 2.0B cant do FULL SCRGB 444 HDR 120hz above 1080p.
if you've an ultrawide load of cheap monitor you must halve the height resolution vertical. So if you want to game in 1080p set it to 720p. if you want to game in 4k set it not to 2160p that doesnt exist for those displays it says half that 1440p.
I am familiar with ancient very old not too great VLC player that simply takes a bunch of old dos trash and puts old linux codecs which as super fake and inferior into one complete package built into the player but many modern features are absent.
You would honestly be better off running KODI. and even thats not the greatest either honestly and has issues with WASAPI not working for reasons unknown? and the direct sound maybe causes some strange distortion or rather normalization issues.
Another alternative player altnerative is KMplayer reloaded or DAUM potplayer. pot player being open source KM player recompiled with some better filters and plugins and settings installed.
but i'd just stick with windows media player for most things and make a text file called config.ini and enable things like HARDWAREHEVCDECODING

i actually have a much much bigger custom config file that turns on more stuff and is rather good i think for a mentally ill man typing AMD display driver words in to try and guess how to use his true military super computer hardware from AMD.
well i found some words on AMD website others on AMD's GPUopen.com
