Acer XB270HU flickering on and off, GTX 980 Ti

Monitors and Displays - www.overclock.net
Hello, my monitor has been randomly flickering on and off intermittently (usually 5-10x in one bout), and I can sometimes hear the Windows sound for hardware being unplugged and then plugged in (it wakes the monitor when the computer is idle). I thought this was possibly a cable issue, so I just bought a new displayport cable, DP 1.2 Accell. Now that I use this new cable, the problem has been much worse and makes the computer unusable. I am running the latest Nvidia drivers.

In Event Viewer I see sometimes this: A caller specified the SDC_FORCE_MODE_ENUMERATION flag in a call to the SetDisplayConfig() API

Has anyone encountered this problem? My monitor is under warranty still since I got it 2 yrs ago and it has 3 yr warranty

edit: also, when these flickers happen (now the frequency is ~1x per minute), the power light sometimes goes from blue (on) to orange (sleep)
