I have a dual screen setup, one is horizontal(primary) the other is vertical, the horizontal one is VGA and the other one is DVI. Sometimes when I press a button on my keyboard to make the monitors come back on(I don't let the computer sleep only let the monitors go off) the primary VGA horizontal one doesn't come back on, I have to physically take the cord out and plug it back in to make it work, no OSD works either on the monitor when it's doing this.
My GFs computer does the same, but she has one monitor. This started happening when upgraded to 960 and Windows 10... so we don't know yet if it's hardware or software related. I guess it's windows/drivers issue as I remember it happening to me once... Btw, my monitor and also hers, would eventually turn on by itself after 1 min or so.
