I recently got a OWC Thunderbolt 2 Dock and am hooking my monitors into it. I have Display Port to MiniDisplay Port going from the monitor to the dock, one thunderbolt cable going from dock to Macbook Pro, and one Display Port to MiniDisplay Port going from a second monitor to the MBP.
Every so often, the monitor hooked into the dock will simply 'reset' or disconnect and then connect again. Everything I had on that monitor moves to my laptop main display and then the monitor appears again.
I have checked the lights/connections and there is no poweroff of the dock. Has anyone else experierenced this or know of a solution?
UPDATE: After switching ports with monitors, the same thing happens with the second monitor in the Dock. It also happens with HDMI to the dock (which is why I went with DisplayPort -> miniDisplayPort in the first place).
