Second screen black screen

[dronjo12]

Hey guys. While i was on my PC my second screen suddenly went black. I heard a low whining sound out of my RX 480 and then the screen appeared for a few and went black again. The second screen is connected via VGA (hdmi to vga) while my main is hdmi (display to hdmi). I switched my VGA cable and the screen came back but i still heard that low whine. After a few mins the screen went black again but my main still works fine. I updated my drivers and everything but still nothing. The second display was tested on another PC and it works fine. Any ideas why this is happening? Thanks in advance :D

Ok so i tried my main screen hdmi into that hdmi port and it works so i guess its not dead, could it be the hdmi to vga adapter then?

HDMI to VGA is a very weird way of connecting a display.
I would suspect the adapter is to blame.

Yeah, its an older display that only has VGA so it was either displayport to vga or hdmi to vga.

I'll try and replace it, thanks

It sucks that the RX480 doesn't have a DVI-I port. It would make things a lot easier.
