I ticked report BT.2020 to display (nVidia only) for BT.2020 although I can't remember why. Maybe someone knows exactly what that switch is for and can elaborate.
Thank you.

Does this also apply if I wish to use two 3DLUT files?

Yes. But if a problem doesnīt show up for me, it is no problem to me.
E.g. why should a nvidia GPU user care about AMD GPU problems or vice versa?
In Windows 10 certain problems can show up which canīt show up in Windows 8. Ok, so itīs good to recommend Windows 8 in a general way.
On the other side many Windows 10 users donīt have problems. Letīs say 5% of the Windows 10 users have problems, which they wouldnīt have if using Windows 8. Then Iīd say: This 5% should downgrade to Windows 8, but the remaining 95% should still use Windows 10.

In my post I simply wanted to point at a personal problem with Windows 10 1903, a hint to maybe delay upgrading for others and the implicit question if someone else experiences similar problems.
Implicit answer: "Your fault, Windows 8 is the better/recommended/right OS for HTPC usage". Thatīs the point.

every 1903 user with new GPU driver get's banding everyone so you going to tell me that 5% and this is not the first time and this will not be the last time.

there is not a single know major problem with win 8 for years.

because you are willing to spend hours to fix win 10 don't except other user to waste there time.

windows 10 is a nightmare because it simply get's updated to often.
do we really need a new WDDM version every 6 months...

I think people are totally overrating the impact of the new WDDM versions, as if that will always break the drivers and cause all issues. And its not like they are just doing it out of boredom, there is actually new and useful stuff being included.

Short recap of recent WDDM additions:
WDDM 2.0 (Windows 10): D3D12
WDDM 2.1 (1607): Shader Model 6.0 (improved parallelism for much better performance), HDR10, Variable Refresh Rate
WDDM 2.2 (1703): VR
WDDM 2.3 (1709): Backend technology improvements for better hardware control
WDDM 2.4 (1803): More primarily backend improvements, support for choosing your rendering device on a per-application basis
WDDM 2.5 (1809): Ray Tracing
WDDM 2.6 (1903): Shader Model 6.4 (ML stuff), Variable Rate Shading

Now you might not be interested in all of those, most are gaming-only afterall, but I would rather have the graphics stack being brought forward then it stagnating just because some people don't like change.

the added feature are not the problem it is the to short time frame. the major issues aren't stopping game mode, deleting personal files, reboot loops and now banding for everyone.
heck i have to buy a new studio mic soon because because 1903 decided that the driver isn't a windows driver anymore for an USB device.

shader model 6.4 will not be used in huge quantities any time soon. using insider builds to provide these new features every 3-6 months is great so developer can create content with these features a proper implementation takes a long time anyway. there is a fine difference between stagnation and forcing it down your throat. windows update have a terrible track record and forcing it out every 6 month clearly doesn't help. how may normal user would be negatively effected by delaying WDDM versions from 1607, 1709, 1803, 1903 for 6 months?

2 and a half month until we get a new WDDM version which will come first the banding fix or this new version your bets are on.

Maybe the display can't do BT.2020 in SDR mode? Or maybe it has something to do with how the 3D LUT was profiled.

What would happen if you select ‘disable calibration controls to this device’?
DCI-P3 and BT.2020 should give you more or less the same colors with current content, but BT.2020 would be considered the correct setting if you aren't using a 3D LUT.

If you disable the controls, it defaults to BT.709 and pure power gamma 2.20.

One reason is for JVC pj users who want to output in 12 bit, the pj uses the wrong colourspace if the option is not set

If your 3D LUTs are for SDR and HDR content, that would work.

FWIW, HDR seems to work fine in Windows 8.1. madVR put the Nvidia card into HDR mode, the TV switches and everything seems to work.

NVIDIA uses proprietary API to enable HDR on Windows 8.1, only with WDDM 2.1 is there an official OS-driven way to do it, which for application developers means they don't need to build that stuff 3 times (once for AMD, NVIDIA, Intel each).

HDR switch has always worked in win 10 with AMD apart from one driver version if memory serves, has NVIDIA broken this again in win10?

Actually 19H2 is not a major version upgrade, its more akin to a Service Pack in the olden days. The next major update will be 20H1, which Insiders in the Fast Ring are testing now.

So there is a good chance it won't actually have a new WDDM version.

I use W10 1903. I have zero banding using nVidia. I'm also using an older driver. I have to. They took 3D vision away recently and before that screwed with drivers so much, non-madVR players started acting up. I don't mind. I don't need newer drivers to keep up with games. I'm interested in watching movies to help divert my attention from the screwed up world it has become and don't need to provide gaming drivers for children. Children who need to get a job more than sit on the couch with a bong and complain they can't play the newest kill or be killed parlay released. Xbox and PlayStation will have to suffice. I'm also using an older card. A 960. It meets the madVR processing I require. I don't need any more. Maybe when I start ripping 8k and need to decode it. I'd much rather keep the O/S updated for free than spend a mortgage payment on the newest wiz bang video card I need like a hole in the head and make my O/S suffer for it. But that's just me and how I roll... right, wrong, or indifferent.

I wish they'd continue introducing major changes only once per year, and half-year 'service' releases like they're doing this year, that way we can just update to the mid-year service release.
The problem is not really the changes, it's good to see advances in technology, it's that it looks like nobody is testing them before release, not even the hardware vendors & software devs.
The change to sound driver architecture in 1903 that huhn mentionned hasn't been talked about much before release (just a note 'Creative X-Fis don't work anymore lol' and no details from MS on their changes) even though it broke a lot of specialty sound hardware. The graphics vendors also seem to discover all the issues only after release.
At this point I just hope they're not gonna change BDA one day and break my TV tuners who are working just fine with drivers from 2009 even though the manufacturer doesn't exist anymore...
I never had problems until now but it's only because I upgrade to a new build after a few months, just before the next one is to be released really.
Preview is the new beta, and Release is the new Release Candidate.

The banding is not a WDDM bug, and there is a workaround for it:

When ticked it's used to autoswitch a jvc projector to sdr -> hdr when using a HdFury Vertex switch

it' at least here known that the issue can be fix by blockign that but that doesn't change that the WDDM version is clearly part of it the problem only happens when the new WDDM version is used.

using a driver that doesn't support the new WDDM version and you will not get banding, on the other hand using a new driver with an older windows build has no banding too.

well that'S bad for my bet because i have my bet on it get's fixed with a new WDDM version.
