It is a known problem. See https://discussions.apple.com/thread/3198411?start=0&tstart=0Re: New Mac Mini with LED 24" LED Display

I put in a 3 meter mini display extension cable between my 24" and the mac mini and the problem has got considerably better. This may sound bizarre, but I also simultaneously touch the metal case of the display and the radiator just in case there is any static electricity that I can discharge. I do this at start-up!!! Probably just voodoo but the screen blackouts/flickers have all but gone. Only happened once in the last week. I'm much happier now. I suggest giving this a try until Apple come up with a download to address the problem.
