It adjusts center mix level in LAV Audio Decoder.

You can also find this option in Codec Tweak Tool.

I've recently upgraded my HTCP from an old Windows 8.1, GTX 1050Ti with MPC-HC and MadVR (unsure of the versions) - all was working fine HDR/SDR.
I now have a fresh Windows 11, RTX 3070 and the latest MPC-HC from here and MadVR Beta 205, I've matched the settings in MadVR (using HDR passthrough setting)
HDR works fine, it switches my TV and Windows 11 into HDR mode, then when playback is completed it swiches it back to SDR mode.
The issue I'm having is with SDR content, when I playback any SDR content the TV and Windows are switched into HDR mode and everything is washed out.
Is there anyway for SDR content to be left as is untouched? I don't want it to go into HDR mode.
This worked previously but I haven't touched anything in years, so there might be something I'm missing, any help is appreciated.

ddjmagic:
Are you sure it's it switches to HDR mode for SDR and not that your graphic driver or video decoder is set to output a limited range? (there's a setting for this both in the GPU driver settings and sometimes in the video decoder codec).

madVR doesn't care about this part like ranges in codecs it usually get's limited range from the decoder just as it should be.
the adjust video colours settings are also ignored by madVR.
the range settings for the HDMI signal are surely something that could be amiss

it also shouldn't be able to enter HDR mode with SDR files...

I can't seem to figure out the right madVR combination to adjust the color and gamma tab for brightness, contrast, saturation and hue for a few HDR titles I will make a special profile for.

SDR adjusts and applies fine - that isn't a problem. Using HDR, I can adjust the settings but they don't have any affect.

I'm using a panel, not a PJ.
madVR 113
Passthrough HDR to display selected.
This display is already calibrated selected.
Send HDR metadata to the display is checked. If unchecked, the picture is too dark to see barely anything.
Enable gamma/transfer function is pure power curve 2.20.
Auto FSE is not enabled.

Guys, how do you check if passthrough HDR "metadata" is working or not? Does this metadata tell the TV to tonemap to either p3 or 2020? Is there a tool to spoof this ?

Is 442.74 nvidia still the last recommended fully working driver?

the first line in the OSD.
display "framerate" (HDR api(if missing SDR) GPU output settings)

if metadata is not send to the display madVR will not engage HDR.
yes i know i'm pretty sure that's not your question.

in passthrough is always saying it is bt 2020.

possible this is not needed meta data but it could be send and used.

a HDfury Integral can and many other.
some AVR will happily show you too.
also some TVs can show this information.

if you can poke the GPU driver about that i wouldn't know how sorry.

551.46 works fine for me but i'm not affected by the majority of issues reported by nvidia users in the first place. i don't think this information is worth much.

Thanks Huhn. So at no point will nvidia tell the TV in passthrough to go p3 correct?

yes should count for all 3 vendor. the signal will always be seen as bt 2020 and the metadata can say the mastering display is DCI P3.

you can also use the custom gamut option to turn it to DCI P3 but the driver should still report bt 2020.

hello, how do you update the installation to a newer version? I installed this in my computer a long time a go with v0.92.17
i downloaded madVRhdrMeasure205 and overwritten the files in my v0.92.17 installation and then I ran install.bat again.
however, when I open MPC-BE options, when I display madVR properties it still shows madVR v0.92.17
thanks for your help.

properties don't tell you the actual version.

so you could be running 205

the install.bat doesn't change settings so it will not harm.

I have been looking for a breakdown of the new settings in the test builds... things like TM curve (Mercury, Mars, etc) and the differences. I haven't been able to find anything, and if someone can point me in the right direction, I appreciate it. Thanks.

I've looked through a few of the threads that are 900 and 3000 pages long. I was hoping someone might know where there was a specific breakdown of the settings for myself and anyone else that might be a layman looking for a place to start as far as learning the settings.

Hi Aumut, there's a lot more to the forum than this thread, you can post a new thread or look for threads about audio processing to see if they answer your question, or would be more appropriate place for this question. This thread is about a video processor only.

With test build 205 (and 204) MadVR/Jriver MC hangs on a black screen (must be task killed) when closing large 4k move files. i9-4060-32gb. Is this a known issue? Is there a work around? Thanks for the help.

My bad, post deleted, and thanks for pointing me to the right direction.
