You dont want a dual DVI cable. Instead you want a dual link DVI cable.

the duel link dvi cable ranges from 80 to 100 dollars depending on who made it. so its not cheap. that is the only way you can get max resolution though.

Agreed. Get the Apple Dual link DVI adapter, works great

You need Apple's dual link adapter and a dual link DVI cable.

Correct.

According to Dell's website that monitor has a DisplayPort input. In that case a simple Mini-DisplayPort to DisplayPort cable should be the best (and cheapest) option to get full resolution.

Something like this: http://www.amazon.com/DisplayPort-32AWG-Cable-Plated-Connectors/dp/B0034X6SCY

Correct. The Dell has DP, an alternative source is here:

You can't argue with $6.99 including shipping worldwide! I just received one of these (in NZ) four days after ordering it, works perfectly on my Dell 30" from Retina MBP.

Initially, I thought getting a mini-DP to DP cable is the solution too.

However, using this cable changes the output from the MBP from RGB to YPbPr which is introducing a "reddish" cast over the display on U3011.

I have even tried doing a calibration with X-rite's Hardware Calibration device i1Display Pro, the cast is somewhat reduced but it still remains.

Really annoying, not sure what the solution is now. I've also read on Apple Store's reviews that even the dual-link DVI cable doesn't work for Retina-MBP now.

MacRumoren, I also have a retina MBP and just upgraded to mountain lion today and am experiencing very similar problems to you with my Dell U3011.

Using both a mini-DP to DP and the HDMI cables I get a horrible pink cast over my entire screen when selecting RGB within the monitor settings. At this stage I can only get normal looking color if I select YPbPr. I have another Dell U3011 here to test and also get the exact same results. My old 2007 MBP running Lion continues to work fine on both monitors in RGB via DVI - DVI.

Haven't found any other information from others experiencing the same thing yet but if you find a fix, would love to hear from you. Will do the same if I come across something.

PS. Did you try connecting via DVI - DVI - Thunderbolt? I don't have that adapter and have been unable to try that so far.

That pink cast is a Apple's "feature" so they can sell the $100 Dual Link adaptor or Thunderbolts monitors. They have a few of these kind of "features" that let them sell more and more stuff.

My next computer is going to be an Asus with Ubuntu.
