Thank you for your response. I have tried to maximize the RDP (RDC) session, and this does not explain why a VM on the Teamviewer host is also showing a black screen. When you suggest checking the quality settings, where do you mean? Is there a Teamviewer setting that I am missing? Finally, are there instructions on how to downgrade the remote host to version 11 or 10 while the machine is physically separated from me? It is currently 1500 miles from me. Thanks.

I seem to have a slightly different problem than has been previously posted. I have a commercial edition of Temviewer host running on a Windows 10 laptop. I send this laptop out to remote sites for maintenance purposes. I connect from my Windows 7 desktop to the remote Windows 10 laptop and perform work remotely. This work includes some scans, and administration of Windows servers. I have hyper-v running on the laptop running a couple of VMs on it as well. Typically I get in, and then RDP into Windows 2008 and Windows 2012 servers and do administrative tasks. Occasionally, I launch one of my VMs and do a scan or two. I was running Teamviewer 11 until recently, and everything was working fine. However, now when I get into my remote desktop and launch RDP into a remote server, I just get a black screen in the RDP windows. When I launch a VM and console into the machine, I get the same black screen. I have rebooted my remote host and my local host. I have upgraded both ends to Teamviewer 12. The remote Windows 10 desktop works just fine. I only have difficulty when I connect to a secondary desktop environment. Any thoughts? Thank you.
