When we applied the latest drivers GPU (520) we noticed that some of the users do have three screens available. We are using a docking statation (Lenovo's USB), but previously there has not been any issues.
If you look the attached picture you can see how it looks. Two main screens, but then laptop's own as greyed.
Users has been used to use the laptops with lid down. But this setup has started to confuse them. What do I need to tweak to get the grey screen away from the laptop?
