[SOLVED] Monitor Backlight Flashes Once During Boot With New Video Card

[BlazingAngels]

I installed a RTX 4080 Gaming X Trio into my system and for some reason when my PC boots the backlight of my monitor turns on and off once. Sometimes before the splash screen and sometimes after. I did not have this problem with my old card which was an RTX 3080 Ti Founders Edition. Not sure if this normal for a RTX 4080 or a problem. The card works with no issues other than that.

Does the single flash of the backlight cause any issues? If the monitor still works the same as always other than that, I would just ignore it.

Changing the boot mode from UEFI to CSM gets rid of the backlight flicker completely.

Well, that's...weird. It's a good tip though because it's something that most people (myself included) probably wouldn't have thought of.

Thanks for the tip, I'll try to store it somewhere in my head without it getting lost. I may have to clear out some cobwebs....

No Problem.
