Now that I have a HDR 1440p monitor... am I supposed to go back to MPC-HC with MadVR instead of using mpv?
No use mpv it just works with HDR
assuming your mpv is reasonably up to date it will default to libplacebo and vulkan and handle hdr and dv and reverse tonemapping gracefully by default. you might want to make sure it can see your icc profile though. just add a line to the config file much simpler than the literal russian spyware that madvr embeds to do the same
searched mpv and madvr on /g/ and /a/ and read posts for the last half hourmore confused than everguess I'll just download both
