P2815Q & Microsoft Surface Book with Windows 10 build 1607
I bought my P2815Q from the Microsoft Store when they were running a promotion last fall. There was no information in the Store indicating that Dell does not support this monitor with Windows 10. When I first connected the P2815 to my Surface Book, it worked (Mini-Display Port to HDMI). Suddenly the combination no longer works and I can't find support on the Dell website.

I doubt that Microsoft would post that at their store, but we did on the P2815Q support page showing the supported operating systems =
