I've got a Roku Streaming Stick which worked very well to mirror my screen or extend the desktop of my Thinkpad Yoga 15 (with dual graphics Intel HD Graphics 5500 and NVIDIA GeForce M840) under Windows 8.1Pro 64bit.
But it does not work anymore with Windows 10Pro 64bit.
I can connect, but the screen stays black.
It's not a Windows 10 or Roku problem as such as it still works just fine with my Lenovo TPT8 and Lenovo TPT10 with Windows 10.
I've tried deactivating the secondary graphics card, I've updated to the latest Intel WiDi drivers, I've run Lenovo Update and Drivers tool, so all drivers should be up to date.
