VGA warning LED showing...

[oldestgregg]

I've noticed that from time to time the red warning LED will be lit up on my Gigabyte z490 Elite board but I've not experienced any problems as such. Could this be a simple bug or potentially an underlying problem?

Possible bug if the pc is still posting and the light goes away then no real peoblem but always wise to keep an eye on it.

Just thought I would update this more as documentation in case it helps someone.

Turns out because I've been using my LG CX 48 as my monitor, if you turn on the pc before the TV and the TV is on a different input then it gives you the VGA error LED. Simple explanation I guess.
