Weird voodoo is happening connecting 2011 Macmini to Dell u2410. My old 09 Macmini connects to this Monitor with a 5m dvi cable and mini-dvi adapter no worries. If I use the very same cable with either the minidisplayport>dvi OR the hdmi>dvi adapters to my 2011 Macmini it doesn't work - no picture at all. I thought I must have a faulty Mac so I reset the smu and pr ram rang Apple, got it check out at a local dealer and its all good! I'm now guessing its something to do with the way the 2011 Macmini talks to the 5m DVI cable. I thought a straight 5m hdmi cable might be an alternative but when I plug in a 2m I had at home I get a nasty grainy image on the u2410 - so I'm guessing this isn't an option. Any thoughts on a solution to this dilemma will be greatly appreciated!
