Question No video signal after cold boot until windows starts

Just rebuilt my rig recently and upgraded to a 2k monitor. After a full shutdown when I go to turn it on again, the monitor wakes up and gives me a no signal message (using displayport) and does not show bios post and will not show a signal until after windows boots. System works fine on a reboot. Wondering if this is a system problem/monitor problem/bios setting issue.

System:
MB: Z390 Aorus Master
Chip: I9-9900K
Bios: F11C
GPU: Aorus 2070 Super
Monitor: Asus VG27AQ

Things I've tried so far:
Full DDU GPU driver strip and clean install.
New Displayport cable
HDMI cable (also late, showed windows boot and still missed bios)
Checked BIOS settings: UEFI, PCI-E 1 as primary video .
Hooked up an old 1080p monitor with displayport: did not have the problem.

Any help would be awesome, thanks!
