4K HDR MKV playback
Hendrik:
I thought about providing different madVR profiles, maybe I'll revisit that idea some time.
If D3D11 mode doesn't become fully featured anytime soon that it might make a reasonable default, I might also think about somehow offering an easy way to opt into either DXVA2 Native or D3D11 for its 4K efficiency, but not sure how that would look.

Since we introduced Red October, we've recommended using it. Customization of madVR isn't something JRiver recommends or supports.

It may not be the solution that you use for MC - or perhaps it could work like that behind the scenes, but do you think it might be possible for the Condition field in custom video mode settings to support expressions that output a 1 or 0, like the example I posted above?
That would work very well for only enabling/disabling custom settings above a certain resolution.
My system can only run SVP on videos up to 1440p in resolution before it starts dropping frames, which means that I have to send 2160p videos to a separate zone.
Reducing that to a single zone would be a massive improvement to my setup.

Jim, when RO was introduced it made a very complex system simple for everyone. You either had strong hardware or your did not, and you could choose one mode or the other. For me, it was probably the single biggest factor to stick with MC - you won my loyalty right there.
To be fair, though, the times are changing now. What was an ROHQ powerhouse system at the time of its release or even 2 years ago, is now not able to keep up with the latest video encoding technology, but can still brute force its way through 1080p videos.
2160p and HDR requires more complex and nuanced settings, and ROHQ as a default does not do well. For example, after resetting all my MadVR settings to default, it wouldn't even produce a picture with 2160p HDR. Some tweaking, and thus discussion of it, must be done for functionality. Unless, of course, a third tier of RO is introduced that will work out of the box for those with the right systems. That would be in the spirit of RO, because the formats that exist have once again introduced complexity.

Do you have 2GB of VRAM or 4 GB on the GTX 1050TI?
Also check that madVR makes HDR passthrough to the TV. On the TV, Deep Colour (or similar naming depending on the TV vendor) must be enabled.

I have 4GB.
HDR passthrough is set in MadVR for the correct device. Deep colour is available for all HDMI inputs on the TV.
I tried a local copy of the files, rather than the NAS, and the issue was the same.
Soon it may be moot, as I shall be switching to a faster system, but it would be nice to get it to work with the current configuration.
