    Hello!

    I can't find the right adapter out there... can someone help me. One ACD goes Displayport to mini DP and into a TB port, the other will need to go through the HDMI port... so here's the question, is there an adapter that will let me plug a non TB ACD into the HDMI port.... every adapter I find online is for plugging a HDMI display into a TB port, not DP into an HDMI source....

    am I taking crazy pills here?

    why aren't you just plugging the second display into the second thunderbolt port?

    Are these the older displays with DVI connectors?

    I am using the other TB port for the ethernet adapter. They are the ones with the mini displayport

    HDMI in OS X only supports 1920x1080 by default, even though the HDMI 1.4 spec allows for higher resolutions (including the 2560x1440 of the ACD). There are a variety of work arounds mainly involving forcing the display to run at 40Hz refresh rather than 60Hz using SwitchResX, but the ACD won't like that and will refuse to display a signal.

    So basically, no. You need to use your two Thunderbolt ports for the displays and work something else out for the networking. Do you absolutely need gigabit ethernet, the older USB>Ethernet adapter worked at 10/100 speeds.
