Hi,
I have a Dell Inspiron laptop running Manjaro with GNOME. I’ve connected 2 external screens: with HDMI and VGA. Both screens are detected, but I can use only 2/3 screens at a time. When I turn off an inactive screen in the settings, one of the just turns off.
Any help would be appreciated.
UPDATE:
when I select resolutions with the same refresh rate for all screens, it works, but maybe there is a way to use 3 different refresh rates so i can get the most of my monitors.
