madVR - high quality video renderer (GPU assisted)

set this up, and report back.

Set your PC to FUll RGB 4:4:4
set MADVR to 0-255
ensure MADVR is set to 10 bit
ensure windows HDR is turned off
set your TV to computer mode
set your TV to colour space YCBCR

play the normal black clipping pattern in SDR, does it look normal, lightened or crushed?

Black clipping pattern just incase you havent got it:

any graphics card will run MADVR, generally the more you spend the more power it will have in MADVR, peoples setups are too different to really recommend anything to people now, even though some try.

If you want 3D however you'll need to stay with AMD or use an NVIDA card with much older drivers.

The correlation between MADVR and gaming is close enough for most so that should be a good enough tell, the better a cards gaming chops the better it will likely be in MADVR, as a very general rule.

However the older RX polaris cards were not as good as the equivalent NVIDA cards, AMD now seems to have made up that ground though.

Best advice, spend as much as your budget will allow.

Do Multi-GPU setups help madVR or isn‘t it optimized for that. For a game which isn‘t optimized for Multi-GPU might be slower than using a single GPU. Driver might also be relevant.

sli CF are not properly supported and usually slow the rendering down.

Hi guys. When I was using MPC-HC native functionality to set TV resolutions based on the video, it would output all video at 1080p, because madVR was upscaling it. Then I switched to madVR's "Display Modes" function, and now it outputs DVDs in 720p instead of 1080p. But why? I have upscaling options at the maximum in madVR, so why it doesn't output in 1080p? My display modes are: 640x480p50, 640x480p60, 720p23, 720p24, 720p30, 720p50, 720p60, 1080p23, 1080p24, 1080p30, 1080p50, 1080p60

Right now I'm playing a DVD at 720x576p50, and it outputs it at 720p. But when I disable "Display Modes" functionality in madVR and switch to MPC-HC functionality, it outputs it at 1080p.
Any suggestions?

UPD: fixed with chros's advice. Thanks.

[chros]

You should only use the native resolution of your display in madvr:
1080p23, 1080p24, 1080p30, 1080p50, 1080p60

I just did use EVR standard and EVR custom presenter for playing a videofile and these wash out the video like 0-255 vs. 16-235.
However since I normally use madVR where it is fine and also in VMR9 (windowed) it is fine.
Playing the exact same video on youtube in Firefox is exactly like VMR9 and madvr.
Need help to find the culprit: driver or Windows or anything other perhaps?
Happens on both MPC-BE and MPC-HC.

[huhn]

the issue can range from GPU driver settings (AMD removed the setting to output full range AFAIK it is still in the registry) up to renderer settings -> output range.


BTW. wrong thread.

[Klaus1189]

But in driver 19.9.2 the pixelformat is "RGB 4:4:4 Full RGB" ("4:4:4" for those who don't know that RGB is always without chroma subsampling.)
But madVR and VMR 9 windowed is fine. Strange, at least for my understanding.

Yeah sorry, for offtopic. Better to continue here, if someone can help me with this issue:
AMD, Intel and Nvidia driver issues and last recommended version

[mclingo]

i hadnt updated my AMD driver for a while but i've just installed 19.9.2 and got quite a nice surprise, although i dont know if microsoft has sorted out some issue or AMD have, I now no longer need FSE for anything, both 3D and HDR work fine with no issues at all, no frame drops or skips and the odd overblown reds issue with sub 60hz SDR has also gone so I no longer need to calibrate for BT2020 in MADVR.

I think i'll take a macrium image snapshot of this as its rare to have a 100% working 3d/4K/HDR HTPC that requires no workarounds at all.

Anyone use this with a FreeSync monitor? I've noticed that when seeking during playback, the monitor refresh rate would dip below 120Hz (the current refresh rate).

[huhn]

that's a bug somewhere. freesync doesn't work with madVR it's best to make sure it is not used with it.

HDR metadata passthrough

In the last couple of days I've talked to Microsoft and NVidia about HDR metadata passthrough. And the current situation is as follows:

1) In Windows 10 Creator's Update there's a new option in the OS display settings dialog named "HDR and advanced color". If you turn this option off, your TV will always be running in SDR mode. If you turn this option on, your TV will always be running in HDR mode. Windows does currently *not* support dynamically switching HDR mode on/off while you're playing an HDR movie (or playing an HDR game)! Microsoft may consider dynamic switching in the future, but don't hold your breath, I'm not too optimistic that they'll add that any time soon (if ever). But let's wait and see.

2) If you switch the "HDR and Advanced Color" option off, your TV will always receive SDR from the PC. If you play an HDR movie in this situation with the madVR option "passthrough HDR content to the display" activated, the OS/GPU will perform a low quality HDR -> SDR conversion behind madVR's back. Consequently, HDR content will look "ok", but the quality is not really good. SDR content will look "perfect", though.

3) If you switch the "HDR and Advanced Color" option on, your TV will always receive HDR from the PC. If you tell madVR to "passthrough HDR content to the display" in this situation, HDR movies should look "perfect". If you play SDR content in this situation, the OS/GPU will convert SDR to HDR behind madVR's back. Consequently, SDR content will look "ok", but it will not be perfect.

4) Currently HDR and fullscreen exclusive mode is a problematic combination. It's partially the fault of the OS, partially of the GPU drivers. It's not clear yet if this will be fixed, or when. Generally, Microsoft wants to get rid of fullscreen exclusive mode. It might suddenly disappear in a future Windows 10 version. I'm not happy about that at all. Which is one of the reasons I've been recommending Windows 8.1 for months now.

5) Nvidia comes to the rescue of all HTPC users who want perfect quality for both SDR and HDR content: Nvidia's private HDR API allows madVR to dynamically switch the TV into and out of HDR mode, as needed. For this to work, you need to deactivate the OS "HDR and advanced color" switch.

6) madVR v0.91.10 had a bug where Nvidia's private HDR API was only called properly in the 32bit madVR version, but not in 64bit. This bug is fixed in madVR v0.91.11.

7) All Nvidia drivers starting with 381.xx up to the latest (384.76) have a bug which results in madVR not being able to switch the TV into HDR, when using FSE mode. You can workaround the issue by disabling FSE mode. Alternatively, using any driver between 376.xx and 380.xx should make dynamic HDR switching work perfectly.

As it stands right now, for all Windows users who want to do both SDR and HDR playback in perfect quality, I can only recommend Nvidia GPUs, because only Nvidia's private API allows madVR to dynamically switch the TV between SDR <-> HDR atm. I'm talking to Intel, maybe they will add a private API, too. Unfortunately my AMD contacts have gone silent. There's still hope for Windows 10, but I'm not overly optimistic atm.

Hello everyone, I noticed my MPC-HC + madVR + HDR passthrough setup is still doing that odd screen thing when you go full screen in windows 10 with HDR on.

Is there a way to fix this yet? Or is there still no way to have full screen HDR in windows 10?

[mclingo]

NOt really sure why MADSHI posted that, AMD cards have had relaible HDR support via AMD's API pretty much since HDR TV's were available, i've only had one driver release which broke HDR and that was a very long time ago.

What odd thing are you talking about exactly?

What can you say about this HDR color issue?
1 - AMD HDR
2 - Windows HDR (Movies & TV)
3 - TV HDR
Source.

thank you for the news, I'll try soon

Hi, not sure what i'm looking at to be honest, I havent seen this movie in HDR so I cant really compare your source to anything, I have the SDR 3D copy. These movies are colour graded in a very specific way to make them look unnatural as well so it hard to say exactly what is wrong.

What problem are you having exactly?

[DMU]

Download "source" and comparison. AMD HDR vs TV player.

[mclingo]

I dont know if there is a language barrier here or not but i'm still not sure what you are asking here, if you want some help on a forum be clear, be polite, dont just dump half formed sentences onto the page and expect people to try guess what you want.

Please explain in clear english, with Grammar exactly what your problem is.

[DMU]

Excuse me for my bad english. I just wanted to say that AMD is still not so good. A problem such as this is still not resolved. I would be grateful if you download that "source" and check with yourself.
