i just did a new install on my workstation but all the connections i tried shows only black screens.
On my other pc its working fine. I already removed an reinstalled teamviewer but this brings no solutions.
I am having a similar problem are you using windows xp by chance?
No the connections i try to create are to win 10, server 2012 and 2016, but it is on all OS, i checked that already.
