Welcome,
I use Spacedesk with Windows 10 and a Samsung Galaxy Tab A tablet. When I connect using a wifi connection, everything is normal. However, when I connect it via USB, it does not connect normally. The tablet can connect to the server, but the screen remains black. The touch function still works, indicating that there is a connection between the tablet and the computer. I tried many solutions, but I was not able to solve the problem. I did everything from restarting Windows and also the Samsung device and activating the file transfer, but nothing happened and the screen remains black???? . Can you help me? Thank you.
