Not able to get dual monitors to work over HDMI and DIV when it boot's

Hello fellas,

im on a: ASUS Z97 Pro Gamer i7 4790k MSI GeForce GTX 1080 x 8gb on a iMac 15,1 with High Sierra (10.13.1) with nvidia web drivers loaded (lilu kext / nvidia graphics fix kext and AppleALC kext - all up to date)

Im not able to get both monitors to work when the system is booting. If i plug the HDMI cable out and boot the system. Mac OS is booting normally with working nvidia web drivers. If i plug the HDMI in everything is working fine(damn it).

If HDMI and DVI is plugged in to my graphics card im getting a black screen when it boots.... but its not the cause of a kernel panic or a lock of GIOLock thing (dont know the exact name).

Somebody was able to get HDMI and DVI to work and could give me some tipps? Or should i buy a DP to HDMI cable for my monitor.

Im sry for my englisch and IOrigs Export / EFI and KEXT folder will be uploaded after work.
