Please try this version and check if the hotkeys change brightness. tinyBrightness.zip

I tried the version you've linked but everytime I click on the icon, the brightness is set to 0% and I can't use slider anymore.

Hotkeys are working on both versions.

My computer has a Windows fresh install. I was running Windows 10 1909 before and the problem was the same.

ClickMonitorDDC 7.0 is working fine with the monitor.

Do you use DisplayPort, HDMI or DVI?

I'm using Display Port. I've also checked with another cable

It's really strange. tinyBrightness uses SetMonitorBrightness and GetMonitorBrightness functions from Winapi. So I wrote a small app to test it: ddcTest.zip. Please download it and send the results here. I'm sorry for taking up your time but I don't have many monitors for testing.

Hello, this is not a big deal and I'm glad if I can help I tried this on both monitors :

MSI Optix G27C2 (DP to DP) --> Works randomly

Samsung SyncMaster (DVI to HDMI) --> Works everytime

Also tried to launch with a verbose flag but there is no output
