Yes. According to MacTracker.app:

External Resolution Up to 2560 by 1600 pixels.

Personally, I would connect the MBA to the Dell over HDMI, and get the highest quality MDP dongle. Apple used to sell its own, but now sells a Moshi Adaptor.

At my school, we use Belkin Adaptors sold on Amazon (at this particular point in time) with a 66% discount price.

  • thanks, DELL U2711 HDMI officially only supports up to 1920x1200, but can be forced to display up to 2560x1600 superuser.com/questions/119755/… But no info yet how to do this on OSX
