Re: Black Screen after upgrading to Windows 10 on the remote machines

I just confirmed that the problem is when the monitor is off. The 
computers are currently in use (monitors on) and I was able to connect 
and work on the remote machines.

I'll ask them to not turn off their monitors tonight so I can test 
whether I can connect when the monitors go into sleep mode.
