I have just bought a new Tv and receiver. When I play a 4K file with HDR the screen turns to a magenta color and looks terrible. VLC will play the file correctly so I know its a configuration of Mediacenter.
The TV is a LG OLED and the receiver is a Denon AVR-X3600
Can someone please help me with the setup.
Thanks

Are you using Red October in video settings? Start there.

Madvr standard 4K playback is fine but no HDR
Madvr HQ HDR turns on but all colors wrong too magenta.

start by feeding the PC HDMI output to the TV HDMI input and bypass the Denon. Not saying the Denon is an issue, but these things are easier to troubleshoot by eliminating as many variables as possible.
I have an LG OLED through a Marantz. GPU is an nVidia 1080 Ti with older drivers because 3D :). Windows 10, but not latest Fall update.
What GPU are you using? Which version of Windows?
What GPU driver version?

If you are using an Nvidia card, some forms of HDR will lead to the green/megenta mess, depending on your video settings (8-bit RGB full range will cause this problem, even though this is what many including Madshit [I think] recommend). I think rips from Netflix have this issue. Funnily enough, older Nvidia drivers did not display this behaviour. One workaround is to get MadVR to convert HDR to SDR using Pixel shader math. The resulting picture has been better than simply passing on the HDR info to the display in many cases.
