Re: AMD FirePro - second monitor

[Jakob Miksch <info@jakobmiksch.eu>]

    I am using the standard display config tool from GNOME.
    
    In the meanwhile I figured out that the second monitor actually
    works on a lower resolution. I do not understand why. This "fix" is
    not ideal, but for my use case acceptable.
    
    I connected my two monitors with a laptop that is also running
    Debian, there everything works without problem - also on the highest
    possible resolution. 
    
    Thanks though for your response.
