PC Graphics

[Eidolon]

TLDR: I can't get my 2 monitors to work at the same time even though they both work by themselves.

I recently got an RX 5700 XT and I'm having a very frustrating issue. I have an BenQ HDMI monitor, and an older VGA monitor that I connect with a DP to VGA adapter but even though if I plug in only one of them, they work without issue, when I plug both of them in only one of them works. If i start my PC with only the older VGA plugged in it works properly, and when I plug in the HDMI monitor both the AMD software and Windows 11 recognize it but there is no signal to it from the GPU. and vice versa, if I plug in the HDMI first the VGA one has no signal even though it's recognized.

I've tried reinstalling drivers, older drivers, using DDU do remove everything and nothing has helped. When I use my old GPU which is a GTX 950, both the monitors work well so I don't see how it could be a monitor issue.

My full specs are:
RX 5700 XT
Ryzen 7 2700
Gigabyte B450M S2H
16GB DDR4 3200 MHz

Any help or pointers would be appreciated.

Managed to fix it... What I had to do is go in adrenaline software and create a custom resolution with the same exact properties as the default native windows resolution for the second monitor. After selecting that resolution in windows display settings both monitors work. I have absolutely no idea why it didn't work with the default resolution, but it is what it is.
