why is my screen black after rdp connection?

I have had a similar issue. While not a fix this is the work around we found to avoid restarting: While one of you screens is black and not showing the mouse the log-in screen is actually there.

Use the keyboard to log into your account (we press Esc a few times, then ctrl+alt+delete, then enter password and hit enter) you will log in and the monitor that wasn't showing the mouse cursor will come back to life.

Again, just a work around I'm afraid but it saves a reboot or two.

I could eventually fix it by pressing WINDOWS-P and ENTER, to choose the active screen. The screen just appears after that.

This fixes it:

Start Menu Edit Group Policy (not sure where it is at in the start menu, or if it is in the start menu, but the type to find worked) Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits Set time limit for disconnected sessions (set this to Enabled and make sure the option is set to Never end a disconnected session)

I just discovered that I could get around this issue by clicking on the login button (arrow icon) with the mouse rather than pressing the enter key after typing username and password. Hope this discovery helps others....
