Hackintosh Displayport 21:9 has black screen

[Tentecrew]

Hello,

I have a hackintosh with an nvidia gtx 980ti from EVGA. This thing isnt faulty as i already replaced the previous inno3D x4 one with this EVGA one.

The situation:
The hackintosh has a gigabyte z97x-ud3h motherboard (had an issue where the vcore would be 1.45v out of the box, fixed that tho)
My PSU is a cooler master g750m and its probarbly fine.
I use a displayport (full, not mini) cable from my gpu to my monitor
My monitor is a 21:9 LG ultrawide (1080x2560)

Problem:
Everytime i boot, i have no display. However, if i switch ports (from displayport-port 1 to displayport-port 2) on my gpu, it works. Then i try to boot again and its black again (Even the motherboard POST is black... So no display at all until i plug it into the othere port)

The hackintosh runs YOSEMITE 10.10.3 using chimera. It also runs windows 10 and has good web drivers.

This is not a driver problem, i think, because not even the motherboard POST works!

I would highly appreciate a good answer D: I spent a lot of money on this machine...

Solution:

Turns out the 21:9 did not recognize it when it had to go out of sleep... Just turning it off / on fixes it 🙂
