JTL Yes, I will go get it now. But check this out, which is where I found it. Advancing the State of Color Management in Windows.
I had to enable it, only available in Windows 11 22H2 and certain GPU using the registry key in the article:
To enable ACM, a global registry key can be used, which will enable ACM support for all SDR monitors all the time:
Locate within the registry the global GraphicsDrivers regkey (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers)
Right click “Add” -> DWORD
Name: EnableAcmSupportDeveloperPreview
value: 1
If the monitor is already plugged in, you will need to disconnect and re-connect it. In case of internal panel, restart the laptop.
Go to Settings > Display > Advanced Display, select correct display and turn on Automatically manage color for apps
It is able possible to enable it for HDR monitors by tricking Windows into thinking your monitor is SDR. I will find the application I did that with as well.
EDIT: That app is Custom Resolution Utility (CRU)
