Here is something interesting. At the bottom of the second display, which is the external monitor connected via the Wireless display adapter, there is a partial task bar with the Start button, Cortana button, and icons for Edge, File Explorer, Store, Chrome, which is running, the Chrome app menu, and Skype, which is running. When I click the Start and Cortana buttons they display on the external display, which I click on the same buttons on the Surface 3 display, they appear on the Surface 3, which is very nice. All other apps display where they were last viewed. #

I should note that I can now use the Wireless display adapter while Bluetooth devices are connected. Under Windows 8 I was not able to use any Bluetooth devices while the Surface 3 was connected to the display. #

I've managed to get extended display to work and scaled the external monitor with wireless display to 125%. Mouse is still a bit jittery. #

I am testing my Surface 3 with Windows 10 and the Microsoft Wireless display adapter. So far, the display on my monitor is not looking very good, and the mouse performance is also very poor. #
