    Hi there,

    I have two screens, one connected via HDMI, and another via Thunderbolt, which goes into thru UA APOLLO audio interface's 2nd thunderbolt output, when my Mac Mini starts up it is fine, for around 5 minutes, but then the thunderbolt display always goes blank, the machine still recognises its there as I can still drag things out of my HDMI screen to where the Thunderbolt screen should be, I have tried new cables, cleaning sockets with antistatic cleaners, the thunderbolt screen works fine with out the hdmi screen being connected and vice versa, any help would be greatly appreciated.

    (I'm running the latest mac mini, with mavericks up to date)

    thanks in advance

    Jack

    I don't see this as a "hardware" problem (unless the "through-connection" via the audio device isn't capable of supporting a sustained video connection due to hardware limitations).

    Rather, seems like something is "going to sleep" on you. Could be the display, could be the audio device, could be "the connection".

    What happens when you remove the audio device from the chain, and connect the display directly to the thunderbolt port on the Mac ?

    We have two systems, to identically spec'd , mac minis running the same screen configuration (two people sharing the same studio) and it is only my mac that seems to be experiencing this problem, nothing is set to sleep, I even installed the app caffeine to make sure of this, I will try running direct without the audio interface to see if it drops out, and i do believe that must be the problem, however I don't understand why on the other mac mini it never drops out, checked all settings and they are identical in every way

    Highly recommended to connect the display first and then attach the other Thunderbolt interface to the display.

    Others to consider:
    Get a different set of Thunderbolt cables, try a new HDMI cable as well.
    Cables do go bad, no matter how many people may try to tell you otherwise. especially in audio and video.
