No Clover Boot up Screen on Radeon Nitro RX580 - Machine is running brillianty though

To clarify - Built a beautifully well running Hackintosh. It's running a Asus Z370-A motherboard, with a Radeon Nitro RX580. Here's the thing. When I plug in my monitor to the Radeon, I get a black screen for a while all the way up to the Apple logo and progress bar, and then it boots up perfectly. I don't see any messages to boot to Bios, I see nothing until the Apple logo.

When I plug in the monitor to the integrated Intel graphics on the motherboard, I get the whole startup as I should - bios message, clover startup.

On the scheme of things this is not a big deal. I recently put in an M2 NVMe SSD, and had to adjust my bios to startup from the new disk, so I put my monitor onto the integrated graphics, adjusted the settings and then plugged it back into the Radeon. Just curious if anybody else has had this happen and if I need to / should fix this.
