To resolve this I've found I can either unplugged/plug the HDMI cable at the back of my projector or switch back and forth HDMI 1 & HDMI 2.
This first instance of this was after altering NVIDIA color setting. I have since uninstalled/reinstalled the NVIDIA GPU drivers. Uninstalled jRiver/madVR and run a fresh. Neither of these resolved the issue.
Edit: It seems enabling D3D11 decoder fixes this. I was hoping to avoid using D3D11 as I pass through HDR to my projector. I then could have used the madVR zoom control for those IMAX aspect changing movies.
What do others do for IMAX aspect changing?. My projector can't blank the image. I guess I could use 'Handbrake' to crop/resize.
Why would you pass through HDR to your projector? No projector can handle HDR as well as madVR handles it. I'd say your cable is probably not up to the task and something about the data output by madVR requires slightly more bandwidth for whatever reason.
