On the new 2013 Haswell macbook air, Im having this weird issue where the external display only works on the thunderbolt cinema display. If you use a HDMI or DVI adapter to mini display port, nothing happens.
The screen will flash blue but then nothing will happen on the external display.
This started happening after my USB mouse started getting laggy and twitchy so i restarted my macbook, thats when all hell broke loose.
