In the Nvidia control panel set your display to use full range 8 bit RGB. Others have also reported the default for their display changing to limited range.

Yes, that was the first thing I changed - which is always required after a driver update.

On Full Range it flashes 20-25.

I had to unlock my calibrated ISF settings, adjusting the brightness from 49-50 got it back down to 17-25 with 16 faintly visible.

Obviously I would prefer to leave it on 49, especially as it seems the culprit is the windows update.

the screen is SDR. so it is clearly not directly out of the source.

I have an Nvidia GTX 970 with latest drivers 22 May 2019. Anyone else having issues?
Do those things really happen? I'm glad to continue in Windows 7.

But the Sony XF90 is HDR, and he says he's using passthrough. What I don't understand is how the screenshots have the proper transfer function. Is that possible with the Windows 10 HDR?

Edit: So when the source is HDR, madVR is tone mapping the screenshots with default settings despite the settings in the screenshots tab (good to know since I was unable to find any information about this), and VLC is also tone mapping but with unknown settings...

The surprising thing is that the results are so similar.

If you are using subtitles I would recommend Kmplayer. It's easier and the subtitles are better than x-y filter and any other players. Kmplayer will use the cpu to render subtitles leaving GPU for Madvr.

Uninstall lav filters.
Install Kmplayer
install lav filter (important to do this so lav filter will be system default)
Kmplayer setting - important that decoder usage internal for video and audio is disabled. Use external and system default for both video and audio. Video processing - general - transform disabled dxva2 checked. Renderer - madvr. Setup subtitles to your liking.

Dear Friends

I would like to buy Intel NUC Kit 8th Generation: NUC8i5BEH and use it to play my 2160p HDR 10bit movies collection via MPC-HC + madVR + LAV Filters. I would like to ask, if some of you have such miniPC from Intel and can confirm, if it works without any drops during playing at 23.976 or 60 (Billy Lynn's Long Halftime Walk and Youtube 2160p60 HDR)?

Will I be able to play also Dolby Atmos and DTS:X using LAV Filters + MPC-HC?

Thank you in advance for your replies.

Sincerely

I don't own this NUC but just looking at the specs I can tell that the iGPU won't get you very far...

You will certainly decode 4K but probably won't be able to use the most powerful features of madvr, especially if you watch 2160p60 content...

If you use Passthrough HDR, it will work fine.

Currently Madvr's HDR tonemapping which is dynamic and superior to typical TV's internal tonemapping requires 1060 (bare minimum) ,, we recommend a 1070 and above.

If you own a more premium TV, The TV's processing may look good enough.

There isn't an Intel API for HDR passthrough. Manual toggle of Windows HDR would be the only option.

a zotac zbox or an box with the same size housing an AMD APU should be cheaper and more powerful at the same time.

this should be relative easy to fix but out of the box unlikely.

Custom refresh modes for Intel also have more problems than NVIDIA and AMD, right? As VAMET wants to bitstream, it's important to keep in mind.

Yes, LAV Filter supports bitstreaming of Atmos and DTS:X. However when bitstreaming you need good refresh rate timings to avoid dropped/repeated frames, and Intel GPUs aren't the best at that.

I have the BOXNUC8i5BEK NUC, and I found the iGPU totally unsatisfactory for madVR use. My 4K TV actually does a better job with HDR10 content than the current official build of madVR, and it supports Dolby Vision. Of course, madVR can't be beat for upscaling everything else, so I ended up buying an eGPU enclosure with a Thunderbolt 3 interface (Razer Core X) and installed the GTX 1080 I had in my desktop. I spent more money than I intended, but now I have the best of both worlds in my living room.

I tried everything else, and even manually editing EDID to force 4K at all times didn't fix it. My theory is that windows loses connection to the TV/Receiver completely for a split second while HDR is being disabled. When loss of HDMI handshake occurs windows briefly goes into 480p, which screws up all your window sizes and positions. Honestly, why windows still can't remember window sizes based on resolution is beyond me.
I'm having the same windows resizing issues. Anyone else having issues with windows resizing after watching HDR (madvr) content?

Are you talking about the media front-end used or the media player?

This may have been asked before many times. Is thre any disadvanatge of using DXVA native instead of copyback in LAV filters? Thank you!

The chroma information isn't presented correctly. D3D11 Native is a better choice for that reason.

Hi guys, been lurking for years but I finally have a question to ask so I decided on signing up.
I have been tinkering with MadVR's HDR to SDR for a few days now, and for the most part everything is looking great, but I have noticed a few little issues that I would like to fix if at all possible.

A couple of examples;

Evil Dead 2. The reds are bleeding into the white area of Ash's teeth and eyeball.



Die Hard. The reds in this scene really overblown compared to most other areas in the film. There is patchiness on the right side of Holly's face and neck.



This isn't just limited to my PotPlayer/MadVR setup. It also happens with the all-in-one MPV Player.

Is this an fixable on my end, or am I expecting too much from HDR to SDR conversion.

The first screenshot is exactly the same in the SDR version. This kind of thing should be checked before blaming the conversion to SDR. As for the problems of oversaturation, there's not much you can do ATM apart from adjusting the color settings on your TV.
