MadVR HDR Passthrough Broken in Win7 and RTX3060Ti

Wolfi · 10th February 2023, 22:59

I buyed a RTX3060Ti, and it works fine under Win7, but one big dealbreaker.
HDR passthrough in MadVR works wrong.
It still activate HDR Mode on my LG Oled TV, but it activate also a very bad HDR to SDR transformation.
This behaviour visible on all, video, desktop, fullscreen and FSE mode, with aero and without.
I lost the real HDR brightness...

Probably NVidia driver problem, but maybe any solution exists for it, example a registry entry or other tweak can change this behaviour.
I read Win10/11 have similiar behavior in some cases, but with windows HDR switch (Win7 not have it)
Maybe NVidia driver check this windows HDR switch, and it is any registry value for it, and maybe set fake value in Win7 for bypass the wrong behaviour?

I have test all NVidia Drivers from 466.47 (First LHR 3060Ti Driver) to 473.04.
Later drivers not work for install, setup not loading, and manual install also not working.
I not know why, for test i installed on second SSD a new Win7 including all updates, but same problem.
But probably with latest NVidia drivers same HDR problem.
And older drivers before LHR cards not working on my RTX3060Ti LHR card (Including inf modification)

With GTX980Ti and same driver versions i used before, are no problems.
I found in internet only one another guy with same problem 2 years ago, he have also RTX 30XX, and with GTX10XX are no problem.
I not sure it is a generally driver problem.
Very interessting question also, the RTX20XX have same problem ?

Sorry for my english.

I have a dedicated thread, but it is for Win10 and Win11.
Do you really want/need Win7?

Yes, i testet all these drivers from 466.47 (First LHR 3060Ti Driver) to 473.04

Switch to new windows is absolutely no way in my case.
If i can not resolve, i will stand with GTX980Ti or buy a GTX 10XX or RTX20XX. (But this is a bad solution, because i wanted and waited for RTX 30XX with HDMI2.1 for have 4K 120hz RGB on HDMI)
In this case it is very interessting for me, people with RTX20XX and win7, hdr is working ?

No way to go to Windows 10? Why? Then it would work. You don't have to buy it. Just use your Windows 7 key for Windows 10. I tried it several times it works.

Klaus1189 · 12th February 2023, 08:54

Another possibility would be getting a 3080 or 3090 and start with earlier drivers like this one:

Klaus1189 · 12th February 2023, 09:44

For 3090Ti there is also a special driver for Windows 7: GeForce Game Ready Driver WHQL 473.30 29.3.2022

Klaus1189 · 12th February 2023, 10:02

For 3080 and 3090 you get also these:
456.38 - 2020.09.17 - https://www.nvidia.de/Download/drive...aspx/163667/de
456.55 - 2020.09.28 - https://www.nvidia.de/Download/drive...aspx/164747/de
456.71 - 2020.10.07 - https://www.nvidia.de/Download/drive...aspx/165697/de
457.09 - 2020.10.29 - https://www.nvidia.de/Download/drive...aspx/166379/de
457.30 - 2020.11.09 - https://www.nvidia.de/Download/drive...aspx/166635/de
457.51 - 2020.12.02 - https://www.nvidia.de/Download/drive...aspx/167114/de
460.79 - 2020.12.09 - https://www.nvidia.de/Download/drive...aspx/167427/de

The first driver is the launch driver for 3080 and 3090 and in the release notes you can read:

Bad idea for RTX20:

If you buy one, be sure if the exemplar you want is not affected.

the drivers are release before the LHR cards release can not use on a LHR card.
The LHR cards have new device IDs.
with manipulate manual the inf, older driver can install, but they not working.
in this case need buy a non LHR card, this is only possible on used cards.
I will do this if i know the HDR problem is resolve.
But i think older (all) driver have the same problem.

I not know which driver he use, but it is one from the oldest.
He the only guy i found with the same problem.

It it not writed in pdf for which windows version, probabbly for Win10/11, and it was some trouble with HDR switch on win10/11

I have test all NVidia Drivers from 466.47 (First LHR 3060Ti Driver) to 473.04
