I just wanted to let everyone know that I have experienced "Bug Check 0xD1: DRIVER_IRQL_NOT_LESS_OR_EQUAL" Blue screens of death whenever my XB280HK monitor goes in to sleep on Windows 10 64 bit, using the latest nVidia drivers (355.60). What I believe to be happening is that my GPU (which is a gtx 980 Ti reference) is trying to poll the GSYNC module whilst it is in sleep mode, which returns an unknown address fault to windows and causes the bsod. Turning the monitor off does not cause this fault, and you can leave the system on and in use for several hours with no fault, but within 2minutes of the monitor going to sleep, BAM. I have informed nVidia of the issue, but I figured I would raise it here.
Also, as an aside, I noticved the Acer website does not even list a Windows 10 driver for this monitor, and whilst it is working (other than as mentioned with the above fault), it surprise me that there is still no updated driver for Win 10. In fact it is still on the same drivers from September 2014. I suppose they could be awesome drivers that don't need updating, but clearly something is causing the bsod issue (although honestly, I expect it to be nVidia drivers).
