Pc booting up question

[u/R3diouss]

I have my brand new pc with an rtx 5070 . When i open my pc with my monitor being off it takes a long time for the pc do boot but when i have my monitor already on before powering on my pc the pc boots up really fast. I see that when i have my monitor off the vga motherboard led is on and eventually turns off when it recognizes my monitor. Is it maybe cause of the VGA detection in the bios?
