EVGA GTX960, yosemite & el captain - no signal in displayport

[ch3m1c]

Hey guys,

I've got my EVGA GTX960 (Superclocked) and I don't get any signal from DP even with latest Web Drivers. Just for info, my Integrated GFX is disabled in bios. DVI works, but my main screen uses DP
Using latest Clover bootloader and GA-Z87N-WiFi motherboard with i5-4690k

Any hints?
Thanks alot

Ok, found out that I had Inject Nvidia checked in clover configuration DP and everything works now

I had a similar problem except my 960 won't recognize my SEIKI 4K TV even in BIOS resolutions.
I can't even get to the clover menu to tell it to inject.

The same computer with the same TV and same cable and a GTX660 works fine.

Anyone else had or overcome this problem?
