    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!

    I use two TB VP2770-LED monitors running at full res and I understand I could connect a third via HDMI but its limited in resolution to 1080 or 1200 (cant recall which, sorry). I dont think you can run three * 1400 displays unless you can try daisychaining TB connections. My VP2770's dont provide that option so cant test, sorry.

    That should work fine. I use 2 1920x1200 displays and 1 1280x1024, and those all work fine. Do you use bootcamp? What happens in windows?

    My guess is it's a driver issue. Do you have the iris pro or the 650/750M?
