Recently, I have tried to combine both the portable version and the installed version. If you are an IT guy and you need to update a PC on your office mates office remotely, you need to hide what you are doing by clicking the black screen feature.
And as an experiment, I tried to remotely connect to my laptop using the portable version. And as it turns out, it is not working on the client side. It seems that when you activate it on the portable version, the installer for the video card does not kick in thus, people on the client side can see what you are really doing although on the server side (where the IT guys is working, he can see the tick box activated).
In this post I will include the picture on how to activate the black screen on Teamviewer.
