4k HDR colors are muted with 1030 video card
curiousMonkey:
The installed driver was dated 9-30-20 but the only version information I found was a Microsoft release number.
Since Windows Update was not selecting anything for installation I downloaded the latest driver (471.96) from Nvidia.
I installed that and loaded the same movie. The results were almost the same. The first test using HDR passthru switched the projector to HDR mode but it remained in that mode even when I stopped the movie and returned to the desktop.
I switched to "Let MadVR Decide" and MC27 stopped working. I restarted it and the movie came up in HDR mode but there was no sound. I assume this is related to an issue with the NVidia HD audio driver which was likely updated as part of my new driver install. I restarted Windows and audio was restored.
The image in this configuration looked fine as well. However when I returned to the desktop, the projector switched back to SDR this time.
I think there is some other issue causing the HDR lock. It seems to come and go randomly as we try and debug the color issue here.
Movies do look great coming from the bluray player.

Tonight I noticed that 4k images were being down converted to 2k by MadVR.
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,

You will always need to tone map your UHD/HDR movies when using a projector, as a projector usually only have like 30-130 nits to work with.
Normally when you use a projector with HTPC and madvr you set madvr to "tone map HDR using pixel shaders" and often also use one of the madvr betas that are around. Madvr beta 113 is the last beta that don't have any date constrains and still works really well.
(madvr usually do the best tone mapping when comparing between a projector tone mapping and madvr tone mapping)
Also, for me I set the NVIDIA resolution to 8bpc, RGB and Full dynamic.
Madvr does an excellent job in handling banding so for me the 8bpc works the best.
This forum thread is a great resource of information.

He cannot tone map with MadVR ... his 1030 is too underpowered with too little vram
Sorry for not respinding in a while ... just could not figure out what can go wrong yet

RO Standard does not use MadVR - so not ctrl+j
