I've got a bunch of monitorss, and everything worked perfectly until I threw my new 4K acer monitor into the mix:
I have an XFX R9-290X
Intel Core i5-3570K
MSI Z77A-G45
and a bunch of monitors hooked up with DVI and HDMI
The 4K Acer is hooked up to the dedicated 290X via displayport
The problem I have: I have my computer set to turn off my monitors after 15 minutes, and when I wake my computer up, I hear Windows play the "hardware disconnected" sound, and all my open programs have been rearranged.
This problem does not occur if I have the Acer monitor unplugged. I have tried the latest video driveers, as well as BETA drivers. I have tried disabling DDC on the monitor.
I need a solution, considering this is a $600 monitor, I did not expect such a huge problem. This severely impacts my productivity.
