I forgot to report that the skin tones are way too reddish, so it may also be related to wide color gamut in some way, but in the amd radeon settings panel there is nothing about it, I tried to switch between rgb full range, limited, YcbCr 4:4:4 etc, but there is no effect, always darkened blacklevels and oversaturated colors

on the tv I tried to change all the settings, but the only one that works is that "setup hdmi hdr", which turn off the hdr functionality for the selected hdmi port

p.s.

another thing, if I leave that option on the tv on, so the hdmi on the tv is able to receive hdr metadata, but I connect the pc to the tv through my avr that is limited to 1080p with no uhd funciontality the black levels are correct

just to dimostrate that is not that option on the tv that turn wcg on for the incoming signal

I also tried to output the desktop at 1920x1080 connecting the pc directly to the tv, but nothing, windows recognize an hdr capable display and black levels/colors are wrongs

Do you have Report BT2020 to Display set in MadVR? Try turning it off. I believe that this option will send HDR metadata even if MadVR is tone mapping to SDR. A dark overly red picture could be a sign that your TV is switching to its HDR picture mode.
