I have just started having this problem. I have several machines running windows 10 with Graphics cards in them. They are not running in resolutions above 1080p the GPUs are being used for H.264 processing.
The trouble is no matter what machine i use to connect to these machines (and there are several of them, the inital connection results in a black screen. Sometimes for a couple of minutes and sometimes the screen comes up with a Ctrl-Alt-Del command sent from Teamviewer.
Both sides are running windows 10. Both sides are runnign Teamviewer 14.1.3399 as of today 1/4/19. Bandwidth on each site is nearly 50Mbps download and 12-20Mbps upload so I don't think its bandwidth related. While the unit I am working on right now is using an NVIDIA GEForce GTX 1050 Ti other sites are using different NVIDIA Cards. However each site acts essentially the same with the black screen.
In addition when pressing the start button in windows 10 the start menu pops up in some strange scaled smaller verision that you cannot read. Then when you actually move your mouse it goes to regular size, however if you scroll it does not refresh therefore going through the start menu is not possible remotely.
I have tried several different resolutions as well as switching between optimize quality and Optimize speed as well as Choosing Best Fit, Original and Scaled in the View Menu. I have exhausted all of my options at this point. However this is a new problem within the past couple of months and its haunting me.
