High Sierra does not provide video signal
After upgrading from El Capitan to High Sierra my mac mini doesn't provide video signal to my television after boot-up.
Fortunately i had screensharing enabled which allows me to access the mac from my mbp.
After connecting with my mbp I can trigger the mac to output video by setting screen rotation to any value.
After reverting to 0 degree rotation i can use the mac again as it should.
That is, for as long as the mbp is connected by a screen sharing session.
High Sierra cuts the video output again once the screen sharing is terminated.
I invite anybody with ideas how to solve this to reply.
