Hi people,
I can not solve the question:
if you install debian8, mint17 and so on. the monitor works fine
if you install debian 9, min 18, etc. the monitor first shows the download, and then completely black.
I tried to install the kernel 3.16.0-4 on Debian 9, in this case the monitor works.
What is the problem?
the monitor is connected to DP-2
