Mouse jumping around screens. Lenovo Yoga 2

[Dougie Fresh]

Have you solve this problem? I have been having this problem for a while now, on Windows 8.1 and then even more often since my update to Windows 10. I can't work out the pattern, it will happen every day for 3 days and then be good for a week. It is only when I have an external monitor plugged in.

However, since the windows 10 update, I also get random seizures, where the computer flashed black and grey like crazy for about 30 seconds and then is all good again, but only when on batter power no external monitor in normal laptop mode (not tent or tablet).

HELP!
