a problem with diagnose

[Ricotta Elmar]

hello fellas,

recently i swapped from 2 difrent 1080p screens one on dvi and 1 on hdmi to Samsung Odyssey G9 on dp

my post led is off so cant see what code it give, but it is already clear it lies arround gpu,

 

my hw

motherboard: asus rog strix gaming e x570

gpu: gigabyte aorus 1080ti

cpu: 3700x

 

but something bthers me since i use the samsung g9

 

the onboard diagnose led (gpu) stays lit when i use the samsung g9

i dont know why but i dont have this problem before, and when i connect one of the other 2 screens that i have aside the samsung g9 the led wont lit up

i also noticed, the bios won't show up when i use samsung g9, the screen show screen when windows is fully booted, and i dont know why,

 

i cant enter bios of mobo when i use my g9 on display port, i updated all bioses and even the samsung g9 firmware

other than this it works perfectly fine inside windows but the led anooys me  bcus it lit up the whole case , its damn bright and i cant settle down now that i know it is burning -.-
