Question Problem with dual monitors.

[Dyvil39]

(first time posting hope it's ok)Plugging in my second monitor makes both of them go black. Only when I remove one other turns on. It worked before changing my GPU. What may be the problem ?

not quite sure but:
Intel core i5-4570
Gigabyte RTX 3050
12gb DDR3(4+8) 1600MHz
ASRock H81M-VG 4 R3.0
SilverStone SST-ST%)F-ES 500W
That should be it.
