Gigabyte RX560 4GB can't boot to Mojave (Black screen, computer still running)

I created Mojave vanilla installer on my iMac mid 2007. During the installation, same issue, can't boot to installer. I remove my graphics card and installed Mojave with iGPU. Using SMBIOS 14,2 , Inject ATI, Inject RadeonDeInit, Inject VBios. Using WhateverGreen and Lilu kexts. Running Mojave 10.14.4 with iGPU

My specs: Dell Optiplex 990 with: i7-2600 Gigabyte RX560 4GB 8GB DDR3 memory DVI OUTPUT(HDMI DOESN'T WORK EITHER)
