Can control but not see remote sessions.

Trying to let someone into my computer remotely and all they see is whatever is on the screen when they open the session. They can move the mouse on my screen, click, drag, and type but they can't see any change on their side. They can remotely access other devices from their side and I had someone else try to remote into mine with the same symptoms so it is definately my side. I can only assume there is some hidden setting that got changed that is doing this. 

I have a Samsung Notebook NP880Z25
