We'll can look into this for you. I'll need to know the motherboard brand/model, as well as the monitor model and the type of video port you're using. I've seen some boards that will hang on POST with a VGA debug with no monitor connected, which creates issues if you're trying to run a system headless essentially.
What GPU do you have or are you testing on the IGP?
Tested this morning with the same motherboard, RTX 3060 and an ASUS VE228 monitor. Tested with HDMI and a DP to HDMI adapter. I'm not experiencing the issue inside or outside of the operating system. I can turn the system on, immediately turn on the monitor, or wait 5-10 seconds, and I get a display.
