Apple Thunderbolt display with a GTX970 and Z87x UD7 TH

[snooz]

Hi, I have a working OS X el Capitan installation with this specs:

4790k
z87x ud7 th
GTX 970

everything is working great but now i want to use one Apple thunderbolt display, I have seen that it is only capable of running it trough the thunderbolt port of the MB, which is handled by the HD4600.

is it possible to run it through the GTX970? or can I use the Hardware acceleration of the GTX 970 without using the GTX 970 video outputs? thank you

Add-on cards like Asus ThunderboltEX II are necessary to inject the video stream of a discrete video card into the Thunderbolt stream of your mainboard. Not sure if it's compatible with your mainboard or if there's a similar solution).

They are only compatible with Asus motherboards and require the Thunderbolt header on the mainboard. This is also true with the ThunderboltEX III for Asus Z170/X99/Z270
