Second external monitor no longer working

My current hardware is a Lenovo Thinkpad T440p.
There are two external monitors through VGA and Display Port connected.
That setup worked pretty well for a number of months. But suddenly the monitor connected
through Display Port (X: HDMI1) does not gave me an output.
I did no system update nor configured my hardware, kernel or rc-system.
The monitor stopped working from a moment to the next but still works
using VGA on it.

I need the second montior work properly but i have no idea how to solve that problem.
