    Hello,

    Okay I have a odd problem ere.

    I got 3 screens. 2 running off display port, 1 off hdmi.

    When plug hdmi in with 2 x DP, 1 DP gets disabled and can only see the HDMI. Why is that, limiting the hardware?

    When I have 2 x DP plugged, both screens are running 2560x1600 (u3011), however the mouse has MASSIVE jumps, like half way across the screen jumps. I dont see this problem when running the DP + hdmi (1080p)..

    Thanks

    Ben

    ah.. damn

    What about daisy chain? The macbook is displayport 1.2 so should support it.

    My monitor does.

    I think it is a GPU limitation, not a port limitation.

    OS X doesn't support DisplayPort 1.2 daisy chaining. Some people have reported it working under bootcamp, but not OS X. The only way you can daisy chain currently is via a ThunderBolt display.
