I have two monitors connected via two video cards (have tried HD6970 and R9 380).
When the system boots, if I am lucky it at least recognizes one of the monitors.
sometimes I even lose that one and the only way to get the picture back is to unplug the DVI cable and replug it.
This is the only way I can get the second monitor recognized.
only started having this problem with new catalyst driver (15.7.1) running on Windows 10
