Will a Macbook Pro retina 15" from 2012 support WQHD resolution (3440 x 1440)? I'm interested in buying the Dell U3415W for my mid 2012 MBPr 15". I know that thunderbolt 1 can drive regular 1440p displays such as a 2560 x 1440, however can it drive the Dell's wider resolution?
I actually tried it, and it worked! Full 3440 x 1440 resolution at 60 Hz using thunderbolt to mini display port.
