VDD HDR not working with OS Build 22631.3880 (Win 23H2)

[KevDaSilva]

I remember having used the HDR version with no issues in the past (probably shortly after the first HDR version had released), but had then disabled it since I didn't use it anymore.
I just reinstalled the driver, and for some reason, the display doesn't seem to work and I can't select any display resolutions (with the default option.txt in C:\IddSampleDriver\option.txt), nor does it let me configure the HDR settings:

I tried it with both the beta and the stable version.

Since I thought the problem must most likely be on my end, I tried finding a solution and reinstalling (both device and driver) several times - without success.
For testing purposes, I then installed the non HDR version - and this one works!
It does the typical zoom in / zoom out animation when first installing it, and I get to select the display resolutions from the default option.txt file. As expected, in the HDR settings it says "HDR not supported".

Is anybody having similar issues? Any ideas on how to solve it?
Thank you very much in advance for any help or input!

In the first screenshot you have the display disabled. Did you try enabling it by settings the display to extend of duplicate ?

Have you found a solution? Same problem for me.
