Ok, fair enough. That is definitely true for SDR.

Madshi, that OS API could be buggy or poorly optimized, have you inquired with MS about it? I wonder if 1809 has improved it.

Is there any proper test content one could use to roughly determine optimal peak nits for tone mapping?

Same here

Please don't quote entire posts for two word replies. We know most AMD users are satisfied with their setups.

Hi Guys,

Please forgive me if this has already been covered in a previous post but I need advice in some of MadVR features involving those who have a 2.39:1 scope screen with a projector.

I have recently changed my 16.9 setup to a 2.39:1 setup and built a new screen. Most of my movies (99%) that I watch on this setup are wide screen format and I use my JVC projector to zoom the top and bottom black bars away and fill the screen with the movie.

I notice that madVR has functions that may assistance with this setup under screen config and zoom control... Can someone with a similar setup who are using these features or someone who knows about these features and believe this may be helpful please assist me and give me some tips...

Also there is apparently a way to overcome the multi format movies (ie Nolan movies) what is the setting for that please?

Thanks I advance for all your help..

i'm using windowed mode with both. Another strange thing with nvidia 4xx.xx drivers, HDR passthrough work fine with mpc-be but not with kodi dsplayer and yet both in windowed mode.
Anyway back to 39x.xx and everything is working as it should.

Oh sorry for not being very clear about it. I was just wondering, because the mapping curves are changed each frame accordingly, would it work like some HDR formats with dynamic metadata like Dolby Vision or HDR+?

Also, I just tested with passthrough and tone mapping with target peak nit at 800 in HDR mode and I noticed some of the bright lines could result in haloing while in passthrough, while tone mapping doesn't and seems to produce a more detailed image, but is also slightly dimmer than passthrough. I personally prefer tone mapping but I'll read more comments here to see what everyone else thinks before I settle down on the settings.

Correct me if I'm wrong but highlight recovery seems to be quite GPU intensive and more so on higher levels? I want to try the "are you nuts" setting because some other users here suggest it might work well in HDR tone mapping mode but with NGU sharp chroma upscaling and tone mapping together it's a bit too much for my gtx 1060 even when overclocked at +170 MHz core clock and +179 MHz memory clock

Sacrifice the chroma, it doesn't make that big a difference most times anyway, go to medium or low, doubt you'll notice the difference.. Personally I'd go NGU AA over sharp for chroma but your choice.

Hi, out of interest, have you moved to 1803 yet, i've been putting this off for fear of problems, there has been much said about AMD card and 1803 on here with MADVR.

Do we have any update on which Nvidia driver works best for custom resolution in Windows 10?

totally agree and reading all the issues around with nvidia drivers....not sure which one is better. Sometimes i had to struggles with specific driver, but generally speaking all is more than good with amd
(win10 1803)

I would set target nits to 480 nits and increase the backlight of your display until the image looks balanced. 480 nits is considered a neutral value for BT.2390 when it comes to compression. I've been using different backlight settings for SDR and HDR content, just adjusting this by remote before and after playback.

There is some more information on target nits in the link in my signature if you're interested.

All of the driver versions should work more or less the same. If one driver version doesn't work, try a different driver version. Also, some driver versions work for some but not others.

Well, NVIDIA also don't have issues, so it might be your own personal issue. We all know that NVIDIA is always performed better when using madVR + MPC.

So far the issue that I always complained is related to FSE mode. I don't even want to use AMD #poorpeople. No offense, but I really don't want to argue with you.

In this world nothing is perfect. I don't know which dictionary you're using. Furthermore, I don't use HDR or any AMD cards, but I dare to confirm that AMD had more issues than NVIDIA when come with into this topic.

I have to say the driver situation is becoming very messy for NVIDIA users at the moment, constant requesrts on here for which version to use. Someone should setup a thread specifically to monitor drivers changes and how it affects MADVR / HTPC playback, we could then just refer people to that. You could then maybe work out which driver works for most people and have that listed as the fallback, goto most stable driver.

if this ever becomes necessary for AMD cards i'd do that.

Windows 10 surely doesn't help to stabilize drivers.
That said, I neither experienced any driver related madVR issue with my RX 560 nor with my 1070 Ti this year. "Good" ol' 8 bit DVI output...

We can all agree on that I think, all this AMD vs NVIDIA is a bit pointless, especially the power vs poverty argument as that is the most irrelevant one as everyone has different needs, stability over power every time for me, I oculd have bought a more expensive NVIDIA card when I got me RX580 but I cant live without native 23,976 support and the stability AMD provide with 3D playback as I am a 3D superfan.

I'm seriously looking into the possibility of rolling back to Win 8.1 on my HTPC. I didn't think I'd be able to originally but the more I look into it and the things I use, I think it's more possible than I thought. I already backed up my Win 10 with fall update installation so I just need a couple hours to pull the trigger and see how stable it is compared to what I have now. The fact that we have to continue to play these driver games is annoying. That's on MS not AMD or nVidia.

If the AMD situation ever gets like that I think i'll drop back as well, have you not thought about switching to RED just to see what life on the other side of the tracks?

Many years ago I was a huge AMD fan but nVidia surpassed them a long time ago. I've no real desire to go back. AMD has their own headaches. I know you've no issue with them and that's excellent. I'm not discounting that at all. I just have zero desire to switch away from nVidia at this point. I suspect that if I get back to 8.1 this week things will probably be a lot better HTPC wise with madvr.
