Monitors not working with docking station

Hi,
I have installed CachyOS with Gnome for the first time on a new laptop. I want to connect two monitors with a docking station.
The monitors are displayed at the gnome screen dialog as well as in the console system listing but the monitors stay black.
Thanks for any advice.
