Connect to the host, but only see black screen
I'm using a windows 7 proffesional desktop to control a windows 10 host desktop. Everything was fine, until yesterday, when i connect to the host, however it shows a total black screen, and the window freezes ( i can tell, because if i select an option from the TV's menu on the top on the window, the menu stays there forever, and if i select another, it just overlaps ). I tried to connect to the host from another desktop ( in the same lan with the first ), and it's working fine. I tried reinstalling, i tried downgrading both, the issue still remains. What can i do ?
P.S. Before the issue appeares, i connected to the host via smartphone, can that caused the issue somehow ?
