Screen disconnects periodically for several seconds

[Alex Johnson]

Approximately every 1-3 hrs my display will be disconnected for a few seconds. The screen goes black as if I had disconnected the displayport cable and then reconnects soon after. I'm using the Intel Skull Canyon nuc with Iris Pro 580 graphics and an Asus MG279Q monitor. This only happens on ubuntu 16.10. On 16.04 using the intel graphics update tool everything works perfectly. This monitor uses displayport to run at 2560x1440 at 144hz and I've had problems driving it with other hardware on linux. I lowered the refresh rate to 120hz and still experience the same problem. I've already updated the bios to the latest version.
