Apple Cinema Display not detected!

[Robin0815]

Same Problem still here.
I have a Radeon HD6870 with Displayport Out and a mdp adapter for my ACD 24".
When trying to enter the bios i get a blue screen.
My cheap acer display is working fine. I guess it is the dp output of the graphics tht causes the problem.

My system :
Z77X-UP4-TH
Xeon E3-1230v2
Radeon HD 6870 (ASUS)

Update:
My 20" ACD now works fine at boot. My BIOS screen is good and no longer scrambled. All I did was make sure that the USB cable coming from the monitor is PLUGGED IN!

What a concept. Apparently Apple's display needs the USB connection to negotiate a frequency at the BIOS level.

I am building my first hackintosh for my 30" Apple Cinema Display.
I will go with Gigabyte GA-Z170X-Ultra Gaming and i5, without any discrete card.
I choose this mobo because of its mDP port.
Has anyone this combo?
Works?

The 30" ACD needs a Dual-Link DVI connector, which your motherboard doesn't offer, so you'd need to use an (expensive) active mDP to DL-DVI adapter.

Thank you 4your quick reply.
I already have this adaptor connecting my mybook air (mid 2013) and everything is ok.
My problem is if the mDP port on gigabyte will work.
I prefer to find a cheaper mobo but then i will need an adapter from my mDP to DP or HDMI, but i read various
