Installed Windows 10 a few months ago and everything has worked well for me except one thing: after booting, my laptop monitor will flash with the W10 boot screen then go black.
I like to use 2 monitors so I plugged the other monitor in and viola, video.
When I checked the Monitors tab in Device Manger it shows a single PnP monitor. I looked in the Event tab and it says 1 monitor was started and configured and 1 monitor "Device not Migrated"
Would appreciate your help and (after reading a few forum topics) promise to "play nice".
