Hi,
just purchased a Sapphire HD Radeon 7790 & realized I could connect three monitors - yay.
On a couple of occasions the smaller monitor connected via displayport has not awakened from sleep. I hear a beep as if removing USB device. Powering the monitor off / on fixes it.
Both monitors connected with DVI awake no problem.
I see threads referring to assigning the displayport as the initial display adapter in the BIOS, however I see nothing in the my BIOS (XPS 435MT) for any display adapters. The GPU (I'm assuming it's the GPU) set the dsiplayport monitor as the #1 monitor in the numbering scheme. My understanding that I have no control over that. The DVI attached monitors are numbers 2 & 3.
Have thoroughly scanned the event logs during that time frame & can find nothing.
Any help?
thank you
