Has anyone successfully got 2560 x 1600 resolution with the new macbook pros (late 2016) *over dual link dvi*?
After a lot of trial and error (I've tried pretty much every adapter on the market) I have my MacbookPro (15inch) late 2016 working with my Dell 3007WFP monitor. Running at the full 2560x1600 resolution. 

Adapters used:


Official Apple Dual DVI adapter.  
USB 3.1 Type C to Mini DisplayPort/Mini DP (Female) Adapter Cable Support 4K UHD  
External powered USB hub.


Setup 


The USB of the dual dvi adapter goes into the USB hub.  
USB-C plugs into the MacbookPro, the female mini display port plugs  into the dual dvi adapter.
