I switched from Red October Advanced to Red October Standard and that seems to help.
Unfortunately the Ctrl-J output is not available so I can’t analyze the settings.
I will leave it this way for a while and see how things go, it is frustrating to see the behavior change each day when I turn in the projector,

Seems need to address your resolution and refresh rate first ...
See attach screenshot of your setting. In box enter mode that MadVR allow to switch ... enter following
2160p23,2160p24,2160p29,2160p30,2160p25,2160p50,2160p59,2160p60
That should cover all pissible scenarios

I added the resolution settings mentioned above and tried watching Flash Gordon.
The picture was back in 4k (no downconversion) but once again the colors look washed out with a lot of additional brightness in picture. I stopped watching the file and switched to the 4k Bluray where everything looked fine.
It sounds like I need to consider upgrading my video card to a GTX 1650 LP or build a new HTPC with a larger case that has room for a full size video card. Both options will likely be delayed while GPU prices remain artificially high.
I am not sure I want to bother with MadVRs tone mapping. The JVC projector firmware does a good job with tone mapping and knows other important details like the age of the lamp and the size of the screen.

Ok ... now resolution anf refresh rate done ... back to HDR
... does your projector enter HDR mode when playing with "HDR passthrough" and "send HDR metadata to display"
... try not to use mouse so the cursor dissapear ... if mouse trigger play control to be displayed ... hdr is lossed
... also do you have secondary monitor connected to you htpc?
curiousMonkey:
The projector enters HDR mode with either "Let MadVR decide" or "HDR passthrough (send metadata to display)".
I had not noticed any issue with mouse movement. I generally try and use JRemote from my iPad to control MC27.
There is no secondary monitor. When I need to configure the HTPC without turning on the projector I use a VNC session from my office.

Did you turn off Windows HDR ... it must be off
