HDMI to monitor gives no signal

Hi,
When I connect my external monitor via HDMI the system reacts with a screen where you choose what to do (switch, extend, etc), but the monitor receives no signal and goes back to standby. The device is tested and works fine with my older laptop also on Manjaro.

Here’s my inxi:

I’ve tried switching to a LTS kernel but it didn’t change anything. Any help appreciated.

Hello, it may be related to Nvidia drivers. Try switching to free drivers (I guess, install free drivers first, uninstall non free next) .
