I'm having some trouble getting a new 15" rMBP to display at 2560 x 1440 resolution on three displays. I have a TBD as the main screen, and two Dell 2713HM as side displays. All three have a max resolution of 2560 x 1440 and yet I can't get them cooperate. The TBD is connected via thunder bolt Display 1 is connected via Displayport to mini displayport Display 2 is connected via an HDMI 1.4 cable to the HDMI port When I connected TBD and Display 1, I get both at max resolution. When I connect the Display 2, Display 1 and Display 2 downgrade to 1080p and I can't change the resolution any higher. When I connect the TBD and Display 2, I get 1080p and max on TBD. What do I need to do to fix this? Thanks!
