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.

Hello everybody,
I am running Debian "Sid" on a desktop PC with the "AMD ATI FirePro W5100"
graphics card. When I connect a second monitor, Debian recognizes it but the
monitor stays black. I can even move windows on it, but I cannot see them.
On the same computer is a Windows 10 partition on which the connection of both
monitors works without problem.
I have installed all drivers like described here
https://wiki.debian.org/AtiHowTo . I also tried to install the proprietary
driver from the AMD website. Everything without success.
Do you have any idea what the problem could be?
I am happy about any hint.
Thanks and best wishes,
Jakob
I assume you are using some version of RandR?
Try searching the packages for "randr".
I use "xrandr" for scripting, but also the XFCE desktop's normal settings dialog for
"Monitors" which runs the xfce4-display-settings program.
Good lick,
