Oh thank you MacPeet very serious info about configurator!!!! frankly it took me 3 efforts to install sierra. Because i tried with the clover 3556 . After a lot of disappointment read carefully that there is a "special edition" clover for sierra.

I removed all nvidia and geforce kext and replaced with nvidia and geforce kext from El Capitan 10.11.5 and system boot without nv_disable=1 and i have all resolution for mine 1680x1050, only problem now is acceleration

I hope so with DP2.

But it is very funny, all cards work even older cards, only the GT610 not.
 
 
Edit:
Until now, problems with Sierra DP2 and the Optiplex 780, is not working. ("timeout kextd AppleACPICPU"-Error and black Screen)
Problems also with Clover Version 3577 and 3585.
Only 3561 works with DP1 on the Optiplex 780.
 
Edit2:
With Clover 3589 now complete installation and DP2 works.  :thumbsup_anim:

I am trying Sierra for the first time but on an Optiplex 980 - so similar but not identical. I am having issues with USB which in 10.11 i fixed with USBInjectAll.kext to get my USB ports working - Did you have any such problems with your Optiplex regarding USB ??
