ADDITIONAL INFORMATION
This sometimes does work but i can't figure out exactly when. I think when there is nothing running it can work but when i have open applications it wont work. Even if i minimize everything and dont touch the pc it dont trigger and monitors stay awake.

When this happens, are there any apps blocking it? You can check in the "Power and Battery" widget.
