After upgrading to Windows 10, I'm unable to connect my Yoga to any external displays. I typically use an HDMI cable with an mini-HDMI converter or project using a Microsoft Wireless Display Adapter. I can't get either to work.tried looking through the BIOS (as recommended by the Lenovo virtual assistant). My driver is also showing that it is having issues (screenshot: http://screencast.com/t/qteCUgTv) I'm unable to roll back my display driver and Here's some info....
System Info: Yoga 2, Windows 10, Intel Graphics Family on driver version 10.18.15.4256 (most recent version)
What happens when I hit Windows+P to project
What happens when I try to connect to the wireless display
Any help or advice would be greatly appreciated!

When I saw your message, I realized that I have not yet tried to project to my Netgear PTV3000 wireless display adapter, connected to my Samsung 55" UN55B8500 HDTV, after upgrading to Windows 10 Pro more than a week ago. I've had my Yoga 2 Pro for about 17 months and it initially worked well projecting to the PTV3000. However, after a month or so, it stopped working completely under Windows 8.1 and I could never get it to work again. After seeing your message, I decided to try it with Windows 10. To my total surprise, it is working perfectly once again. I did a "clean" upgrade to Windows 10 and have installed all of the latest Lenovo drivers and the latest Intel graphics driver (version 10.18.15.4256) which was installed automatically during the upgrade. It's great to have it working again. I wish you luck in getting your "projection" working again. So far I'm very pleased with the upgrade to Windows 10 Pro even though I had a hell-of-a-time doing the upgrade. I was forced to do a complete factory reset and add all of the Windows 8.1 updates (which took well over a full day) in order to get the upgrade to proceed.
