Hi Gang, I have an Early 2014 13" Macbook air. It is running 10.10.3. I am trying to get it to display 1440p onto my external monitor using a mDP to HDMI adapter. It, however, is stuck at 1080p with no options to go higher. Here is the kicker, tech specs say that it can achieve this resolution. I have another system, a Late 2013 rMBP 13". This system confirms that the cable and monitor both work up to 1440p. Just when I switch systems it goes back to 1080p. So I am pretty sure this is the mba's problem. Anyone have any insight?
