When I turn on HDR in Windows control panel, the screen immediately becomes black and it still doesn't show anything after a few minutes. When I run games that support HDR, everything works fine. And when I connect another PC to the same monitor and enable HDR, everything works fine too.
Any ideas how to fix this problem?

There's a key in the registry that holds all the profiles for screens you've connected to in the past, such as orientation settings.

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\GraphicsDrivers\

Three keys in here are commonly referred to to clean up if you want to remove this history:

Configuration

Connectivity

ScaleFactors

... but there's a fourth one that is also relevant:

MonitorDataStore

Here is another set of screen profiles and under each one you'll have one value called:

"AdvancedColorEnabled" was set to 1

I've deleted the entire monitor datastore (for my specific monitor), disconnected-connected the HDMI cable and it worked!

You could try doing Ctrl + Windows + Shift + B after enabling HDR and having the black screen, if the GPU's driver was successfully restarted you should hear a little beep noise.

You could also fully reinstalling your GPU drivers by:

  • Fully remove your previous GPU drivers using DDU
  • Install the latest stable NVidia GPU drivers

If none were successful you could try another cable and/or another port on your GPU. Last resort that would most likely work would be a full clean install on Windows...

With HDR, you have a problem when connecting the monitor via HDMI. Using DisplayPort, it works fine without a problem.

You have updated your graphical driver, your monitor doesn't seem to have a firmware update, so as regarding software you have done the maximum possible for an end-user.

You may still check whether your Windows 10 can be updated to version 23H2 (a small chance of it helping), or check for more updates to your computer, such as for the BIOS/UEFI.

You may also check if your HDMI cable supports HDMI 2 (the higher the version the better), or try a higher-quality cable.

But if nothing helps, I would chalk it up to gods of incompatibility, and keep on using DisplayPort.
