[Help]Dual monitors in hackintosh

After I've followed this guide and successfully installed hackintosh on to my pc I have a problem. I have 2 monitors. The main one plugs int the DP in my r9 380 4gb and the second monitor goes in to the DVI port. The second one at first didn't get any signal. Now is even worst, it dose the mirror image from my main monitor but is jittery/shaky. How can I solve this problem? I want to use a dual monitor set up in the end. Is there a need for the specific model of monitors?

My rig:

CPU Intel i7 8700K

CPU Cooler Master MasterLiquid 240

ASUS PRIME Z370-P

MSI RADEON R9 380 GAMING 4GB

2x ADATA XPG Gammix D10 Black 16GB DDR4 2400MHz

2x SSD Intel 760p Series 256GB m.2

SSD Kingstone v300 240gb SATA III

2x WD Red 2TB SATA-III 5400RPM 64MB
