    At random my Monitor turns black. I have phoned dell and got a new U2713hm sent to me, but sadly this problem is still happening.

    I have replaced the monitor.
    I have replaced the power cord.
    I have replaced the DVI cable

    The only thing I have not replaced is my Display Pork to Dual Link DVi adapter or my Mac mini.

    I have ran diagnostics on my Mac Mini with no problems showing. I am tempted to take my mac to a local apple reseller and see what they say.

    Energy save is set to around 45 minutes for the monitor.

    Any suggestions?

    Why wouldn't you use a cheap display port to mini display port cable?!? The cost like $5 and then you don't have to use a problematic display port to dual Dvi converter...

    Because that cheap display port to mini display port cable will not give me this.

    Have you tried a different video connection?
    Mini DisplayPort to DisplayPort should work.
    (Did you, in fact, already try that?)

    AFAIK, that should also give you the full 2560 x 1440 ...
    And, would eliminate the need for that dual-DVI adapter.

    Yes it will. A cheap display port to dvi will not but display port to display port will. I currently use two of them for my 1440p monitors.
