CSM HDMI Issues

Hi all,

I just built a ryzentosh using opencore and am having one problem. When I disable CSM in the bios, I get no display until the Apple logo unless I only use a single DVI display. My main display is hooked up via HDMI, which means if I wanna see the opencore menu and boot into Windows I need to unplug my primary display. Any thoughts on a fix? My specs are below

MOBO: Gigabyte AORUS B450 Elite CPU: Ryzen 5 3600 RAM: 16 GB Corsair LPX 3200 MHz GPU: Sapphire RX570 4GB Macintosh HD: Samsung 850 EVO 250 GB SSD

EDIT: I need to disable CSM otherwise I get a kernel panic.
