There is also the option to use an older pre-WDDM 2.2 driver, like 378.xx.

And the custom resolution trick:

HDR Playback, need some help

Can someone provide simple instructions on Window Settings and MadVR settings to get HDR to work.

I have a GTX 1080 TI, Windows 1703 and and HDR TV (samsung KS8500),

1. I can get Windows to display HDR if I select the silder to HDR, but then it is aloways in HDR mode no matter what I do, and everything looks like trash.
2. I can disable HDR in Windows, and then use mdavr, using DX11 Playback. I have passthrough HDR Content to the Display selected.
2a. Nvidia's private API
2b. Windows 10 API
In both cases playing back of an HDR video such as "LG_Chess_HDR.mp4" or "Sony_4K_HDR_Camp.mp4", does not switch to HDR mode, according to the TV. The splitter is LAV and the decoder is LAV, so I do not see why madvr is not sending HDR10 data.

I also have an HD Intergral inline so I can monitor what is happing and the Intergal in both cases shows I'm not passing any HDR10 data, so the TV seems correct.

What am I doing wrong?

I am having so much fun with HDR. It keeps getting stuck in that mode even though I turned it off in Win10. So SDR gets incorrectly tone mapped. If I switch from 10bit to 8bit in MadVR settings I can get it back. Either that are rebooting fixes it. But then I have to mess about getting HDR working again as it does not like switching to HDR without clicking on MadVR's system track icon, leaving it for a few seconds then clicking away. I hope this is fixable and not something Win10 or the driver is doing.

Using newest madvr 0.91.10 causing Potplayer to close really slow and start really slow, I can't click on movie instantly after closing potplayer, I can see potplayer going from 100+ mb of ram to 35mb and then close which takes about 4-5 sec, within this time it doesn't open another movie or the same movie cause I limited it to 1 instance of player. without using Madvr , just any other renderer , potplayer closes fast and opens fast. 0.91.9 worked properly without an issue.

EDIT : Nvm , it still happens with 0.91.9 , I figure it's the new update, he changed something for people who have crashes , might kind of timeout which doesn't close it instant. with version 1.7.1916 it works like it should. Still for some unkonwn reason, potplayer opens when the internet is disabled ! , can anyone figure out why !? it opens the movie instant without internet ( network adapter disabled ) compare to with internet takes like 2-3 sec saying it's opening ...

I'm gonna ask again because I didn't get a clear answer the other time.Will I have a benefit if I leave smooth motion always on in 60hz for 29/30 fps movies?

Using it always is pointless in my opinion.

Which is the better alternative: 60hz with smooth motion or custom refresh rate 72hz with reclock?

Why not 50/75Hz custom refresh rate?

To playback what sort of source material? 72Hz is good for 24fps material. 71.928Hz is good for 23.976fps material.

Depending on your screen, you might be better off implementing a custom resolution for 23.976Hz, because the screen might already be working "behind scenes" to multiply it in order to reduce flicker.

You should just disable game mode and the game bar if you don't want them and think they intefer - if your alternative is to not use CU anyway, you also don't lose out on anything you wouldn't have anyway (not to mention that game mode is largely irrelevant anyway).
Come over and we test it together:
1. Stock Win10 x64 RS1 + run Windows Update + NO TWEAKS + install latest NVidia drivers + install latest MPC-HC x86, LAV, madVR, ReClock = no issues with playback
2. Stock Win10 x64 RS2 + the same as above = severe frame-droppping with exactly the same settings.

I did this comparison several times and you're wrong to say I am the only one. Windows 10 RS2 does bring significant changes to the way it treats video drivers, refresh rates, adds overlays and "Optimizations" to FSE. There is no way to get rid of it. Its integrated into the OS, most likely hard-coded into DWM.EXE. Just because you aren't getting the same problem does not mean it is not there. As I mentioned, I do not have this RS2 frame-dropping problem on all of my displays, just one of them, and the other 2 work the same way with either edition. It just happens that the one display that has issues with RS2 is my TV!

On my i5 intel iGPU pc, among Potplayer and Mpc-HC/BE, Potplayer gives me the best madVR result by playing 4K/HDR clips, no dropped frames, no glitches, lowest rendering ms and full filled queues. The same madVR setting on Mpc-HC/BE drops lots of frames, means unwatchable. Maybe Potplayer internal decoder is better than the others, I'm not sure.

Madshi, with D3D11 I still get some frames presented from earlier in the video when I jump forward on my HD4000.

Mostly for 23.976 fps material, my monitor can't handle 23.976hz, and madvr acts weird with 71.928hz. 72hz is ok.

Better is the third alternative - 72 with smooth motion and reclock, of course.

why should you use reclock AND smoothmotion at the same time?

it should work together but still why touch the audio or video if it is clearly not necessary.

Use SmoothMotion at 72Hz, then. No Reclock needed (if you need WASAPI you can use Sanear... or Reclock I guess, but no x64 in that case).

I made 71.928hz custom refresh rate again, to see how things will behave, personally I don't like the blur that smooth motion adds.

The closest to 71.928 hz I could get was 71.931 hz...anyway looks ok for now.

Returning to the issue of oversaturated colors of some videos on wide-gamut displays:

For the sample video, I made the following test: in the video player that was using madVR, switched to interpreting video as full range (via madVR shortcut) and made a screenshot in PNG. Then opened it in Photoshop and analyzed the values in the areas of these artifacts.

Red areas were indeed oversaturated in R channel (highest R was 255), but G and B were less than 252 (and even less that 235 in green area), although R values were 0 (or close to zero) there. So, most of the visible problems are in areas with R not in range 16-235 (or even 1-254).

Here is the captured frame:

of cause i have no clue how much work that is.

As for the range of the original video - I couldn't understand your answer on whether it's limited or not.
should be limited(a normal video). it is not worth to check it with a histogram and the issue has nothing to do with the range anyway.
It seems that either the video is badly encoded, or it is wrongfully interpreted.
Anyway, does it really has any sense to have values 0 and 255 pass to 3D LUT then?
