Second monitor not waking up

So I've updated to Win10 and my drivers to 353.62 My screens shut off after 15 minutes (standard setting on windows) and when I move the mouse only one monitor turn on. Pluging it out and in again doesn't help. The only thing that helps is a restart of the system.

It doesn't show in the display settings, can't be detected. Only one monitor shows up.

This only happens if I leave the turned off displays alone for 30+ minutes. If I move my mouse (or press a button) immideatly after they turn off, then they will turn on both.

weird: sometimes its the left monitor, sometimes its the right one.

I've already done a clean install of the driver.

(sry for crappy english, I'm tired and this is not my first language)
