Seems more like a Linux Driver/Display Port disagreement (or maybe your hardware) than DisplayPort as a spec. DisplayPort has been spotless on my 2012 MBPr under OS X and Windows. Ditto at work for numerous Lenovo, Dell, and Asus laptops running Windows and various flavors of Ubuntu.

DVI on the other hand, on my MBPr, will occasionally spaz out and display static. I've tried with multiple monitors of the same model with to same effect.

(For what it's worth we pretty much use only Dell 2412 monitors at work).
