    The Mac Mini is connected via Thunderbolt to a seagate dual port thunderbolt drive. The Dell U2711 is connected to the Seagate via the 2nd Thunderbolt port using a MiniDisplayport to Displayport connector. I am then using the HDMI port on the back of the Mini to an LG Flatron M2760


    For some reason, whenever I try to set-up dual screens, at some point, the Dell U2711 will all of a sudden just go to sleep. The second display will remain and be active, but the Dell will not show video. The only way to get it back is to reboot.

    I initially thought it was a bad cable, but i have since replaced it and the issue remains.

    Any ideas are appreciated

    Connect the Dell directly and see if it happens. If it doesn't, then you know it's the Seagate.
