Hi All, I've got an early 2011 MBP w/6490m and 2 27 inch monitors (2560x1400). One monitor is a dell U2711 and the other is a Thunderbolt display. I had been working fine with both monitors at 2560x1440 pre update and now the dell monitor is stuck at 1600x1200. My configuration is as follows: MBP > Thunderbolt display > Caldigit Thunderbolt dock > Thunderbolt to DVI > Dual link dvi cable > Dell monitor. I'm confused as to why this would work pre update and not after. Any suggestions?
