Can Retina iMac run at full resolution in target display mode?

 

[aggri1]

In short: no.

Longer: it can't run at any resolution: Target Display Mode has been dropped from the Spec' sheet. It was listed under "Video and Camera Support" for the old models: http://www.apple.com/imac/specs/.

This makes perfect sense given the bandwidth limitations of Thunderbolt compared with the requirements of a '5k' display.

No more iMac-as-a-display. Sorry. 🙁

There are lots of very disappointed Mac pro users out there who firstly didn't get a tb2 display and secondly they can't use one of these in target using tb2!
