Welcome
Maybe someone can tell me how you can watch HD, Dolby Vision on a regular SDR screen, there are just no problems in Windows, set MPC and turn on the madVR render everything. Wine - not at once
in VLC - I did not find how to implement it.
Have you tried MPV player? I think it comes with Zorin.
That looks like stuff for Windows.
@zkv do you have zorin-os-restricted-addons and zorin-os-restricted-extras installed? Might just be a missing codec. I couldn't play certain things myself on a fresh install; those cleaned it up.
