HDR10 & Windows 10 post-Creators Update

Has anyone on Sup Forums gotten HDR to work with Windows 10 and nVidia GPU post-Creators Update?

>nVidia control panel does not allow for 4:4:4 10bpc w/ full range.
>Allows for 12bpc 4:2:0 which causes banding and too dark image.

>Windows "HDR & advanced colors" either causes too dark image (if you force 12bpc 420/422) or way too washed out colors.

>mpc+madvr = washed out colors OR brightness gone.
>mpv = same.
>Movies & TV (W10 program) = image looks like SDR processed to look like HDR, but brightness and grayscale is gone here too.

>Resident Evil 7.
Grayscale/mediums gone, but not brightness.

>Hitman (2016)
Grayscale & mediums are nearly gone, and so is the brightness.

>F1 (2017)
Ultra bright image and colors are like neon colors.

The thing I noticed the most is that brightness of any kind and greyscale / medium colors are completely fucking washed out which makes the image in games or films look terrible.

Both my GPU and TV support HDR10, I used a HDMI cable that came with 4k device. I tested HDR10 sample with PS4 Pro and it-just-works.

>nVidia control panel does not allow for 4:4:4 10bpc w/ full range.
It does, but your display doesn't. If you're trying to push 4K60Hz@4:4:4 10bpc, no current HDMI standard supports that bandwidth.

>Allows for 12bpc 4:2:0 which causes banding and too dark image.
Then use 10bpc, dumbass. Regardless, this shouldn't cause either of those two things. Your display or GPU should dither for you, and the brightness should be identical because they're both still BT2020.

It all works for me. mpc+madvr plays HDR content correctly, and all games play correctly.

Yep, it should be identical but it is not. Only time I got the brightness working was with RE7, but it also included washed out mids/grayscale when running under Default Application Settings (N-CP). SDR content played without HDR modes looks better than HDR content played on HDR mode (pick any of the three players I mentioned).

Testing things out with
>developer.nvidia.com/high-dynamic-range-display-development
this, made it easy to pinpoint out which fails and its the grayscale and NIT brigthness which are both too fucking low.

Can't seem to be able to fix it on my own.

Nice hardware Mr. Moneybags.
Are you sure you're not confusing "washed out grays" with what HDR actually looks like? Windows 10 looks pretty garbage in HDR mode because all the UI is calibrated to 100 nits (so you don't burn your eyes out), which is relatively dark for such a display, so it all looks quite gray even though it technically isn't.

>grayscale and NIT brigthness which are both too fucking low
What's the max brightness of your display? I thought this information was exchanged during HDMI signals, or should be. Are you sure your TV is also switching to the correct colour space automatically? If it's still in sRGB colour space in HDR, you're going to have strange artifacts.

I'm running in 10bpc 4:2:2 by the way, which is the mode I see most others run HDR on Windows with.

HDR is part of the Windows 10 fall update.

I haven't even got the creator's update yet. No idea why, it certainly badgered me about redoing my privacy options for it enough.

I can't even get full range with 8bpc 4:4:4 YCrCb, which is weird because the U2414H does full range RGB. I don't understand why. I've given up.

I figured out that Windows was calibrated to low brightness with HDR for that reason, but should that extend to films and game media too? I don't think so.

the LG is 700 nits maximum brightness and seems to work properly with PS4Pro HDR10 media. I'm not sure about the correct color space the TV sets when it switches to HDR when you play HDR media FSE.. I should check that out (but last time I checked, you couldn't change much from it).

Might be for displayport only, that's the way 10bit colors work for the 32 Ultrasharpie IIRC

Yeah, just checked. LG changes to correct color space when it switches to HDR and wide color gamut is enabled.

Looks like Windows issue or nVidia driver issue.

>I figured out that Windows was calibrated to low brightness with HDR for that reason, but should that extend to films and game media too? I don't think so.
I don't think the calibration can change on a per-window basis. Applications need to go fullscreen to enter exclusive mode where they can override to what they want. madvr only enables the correct HDR mode in fullscreen exclusive mode, and same goes for games.

RIP. We're still in the early days of HDR support after all.

I’d just like to interject for a moment. What you’re refering to as Windows, is in fact, NSA/Windows, or as I’ve recently taken to calling it, NSA plus Windows. Windows is not an operating system unto itself, but rather another locked down component of a fully functioning NSA system made useful by the NSA corelibs, shell utilities and vital system components comprising a full OS as defined by the government.

Many computer users run a modified version of the NSA system every day, without realizing it. Through a peculiar turn of events, the version of NSA which is widely used today is often called “Windows”, and many of its users are not aware that it is basically the NSA system, developed by the NSA.

There really is a Windows, and these people are using it, but it is just a part of the system they use. Windows is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Windows is normally used in combination with the NSA operating system: the whole system is basically NSA with Windows added, or NSA/Windows. All the so-called “Windows” versions are really versions of NSA/Windows.

>enables the correct HDR mode in fullscreen exclusive mode
Yeah, *when* it does. I had a bug last night when trying this. It enabled HDR (the faulty looking) in non-FSE, when I turned it to FSE it went away - and when I restarted my PC it started working as you describe it (HDR on when you make MPC FSE and gone at windowed).

At least I can always plug media to TV and it will work with HDR, but it would be nice to get it working with Windows itself properly.

You don't have any issue with grayscale or medium colors? Good for you, mate.

Next time you're too stupid to understand a thread, just don't reply and save yourself the embarrassment.

>RIP. We're still in the early days of HDR support after all.
HDR is a stupid fad that will die soon anyway

I've implemented HDR in multiple projects and read more ITU-R specs than you ever will in your lifetime; but sure, whatever. I'll leave the thread, have fun figuring out HDR

Might also just be one of the U2414H's many isssues.

>You don't have any issue with grayscale or medium colors?
Define "issues"? Windows in its current state still looks really ugly in HDR mode. I don't enable it unless I'm playing games or watching movies. I run in 8-bit RGB for the rest.

>HDR is a stupid fad
Yeah sure let's just run all run on BT709, a colour standard designed 30 years ago, forever.

Windows 10

>nothing incorrect about the OP picture
>hey guys look at me I know everything and you're stupid
Not only are you not proving anything, but you're also reaffirming that you're stupid. A picture of the corresponding relative colour spaces of different HDR standards, what's not to get?

I am running Windows 7 with all updates (with Spybot anti beacon) because it does what I need it to do and it has the software I need. It doesn't have a buggy half-baked UI like all of the alternatives do (with exception of MacOS).

So there is no real alternative to NSA spying

1. that's not how colorspaces or HDR standards work
2. the picture is LITERALLY lying; a 5 sec google search could tell you that HDR10 and Dolby Vision both use Rec. 2020

>So there is no real alternative to NSA spying
GNU+Linux

The video primaries have nothing to do with the dynamic range, sweetie

Sorry, there is no usable* alternative

Oh THAT's your complaint? 90% DCI-P3 coverage is enough to allow a label saying that the TV supports HDR though, so it's not exactly wrong. That defines it as supporting a "wide color gamut". I don't think any displays currently support the full Rec.2020 space anyway.

That's exactly the problem, sweetie.

I know Windows looks piss ugly in its HDR+Advanced Colors mode, but what I meant that you don't experience any problems with medium range shadows/brightness and medium grayscale in your films or games?

It's like the image is either incredibly bright or incredibly dark with contrast at maximum and no in between (Resident Evil 7).

And if I play film with mpc-hc+madVR (or Movies & TVs application) I get a really flat image even with HDR test sample and SDR files look way better. It's like the wide color gamut of the LG panel doesn't fucking work under Windows itself, and shows the HDR with limited color space.

Okay I'll develop special for you a BT.709 HDR monitor, then you should be happy, right?

I just gave it a shot. It doesn't work for the U2414H. Oh well.

>SDR files look way better
SDR films look better when played in SDR mode*.

It's really weird interaction.

Hmm no I'm not having that. When you run RE7 in HDR, you get to calibrate the settings for it, brightness and all. Even after setting those correctly you still have those issues?
Setting up mpc-hc+madvr was a real pain and a half. Open the madvr OSD while you're playing a video fullscreen to make sure it says it's in BT.2020 mode and HDR is on. It could very well be a support issue with LG and Windows though.

I don't think it is LG issue when I can just put a physical drive to the LG and it plays back HDR test samples correctly, or plug in PS4 Pro and it plays back HDR films correctly.

Yeah, I had the issues even after tinkering with the two options RE7 provides for adjusting max brightness and brightness itself.

>Open the madvr OSD while you're playing a video fullscreen to make sure it says it's in BT.2020 mode and HDR is on. It could very well be a support issue with LG and Windows though.

It is. HDR pass to display, and correct color space set, yet it looks like limited mode.
