I don't even know how to begin to search for this problem and my Googling has failed so far. As per my question title these are the facts:
- I have 3 monitors on 1 graphics card and everything is native
- My power settings keep the system on but the monitors sleep, however, one of the monitors backlights stay on so the screen is black but not off
- On wake, my open windows have moved, but not necessarily onto the screen that had the backlight on
And finally, all this hardware worked normally on Win7Pro before I upgraded this computer to Windows 10 Pro. The only change was a new HDD with the new system.
How can I even troubleshoot this? Any ideas?
