I am attempting to use the KVM feature. My primary PC (desktop) is setup for KVM and my secondary computer (laptop) is also setup. When I connect, I get nothing but a black screen. I have scoured the forums and I think I know what the problem is however none of the solutions I have found were successful. 

My laptop has an integrated GPU and a dedicated GPU (for gaming). I have taken all the offered solutions (ensuring all drivers are up to date, forcing all programs in use and a system wide, commanded to use the dedicated GPU) and nothing is working. I don't have a secondary monitor for my laptop so I am unable to test the "dummy" plug solution. Also, I shouldn't have to buy anything extra to make the product work, in my opinion.

I have spent about 6 hours troubleshooting and trying different settings.

I would like a full refund.
