I'm trying to get multi-monitor support working on my setup. I have a GIGABYTE B550M K motherboard, a CPU without integrated graphics, and I'm using an AMD Radeon RX 550 GPU with 4GB of VRAM. I've connected a second monitor to the GPU, but only one monitor turns on. The working monitor is connected via HDMI, while the second one uses a DisplayPort to HDMI cable.

Hey, just a heads-up, I ran into a similar issue and forgot all about the drivers! Make sure everything is updated. Sometimes that’s all it takes to get things working smoothly.
It sounds like there might be an issue with the cable you're using. Just so you know, DisplayPort to HDMI cables aren’t bi-directional. This means that DP to HDMI isn’t the same as HDMI to DP. Also, you typically don’t need to change any BIOS settings to use multiple monitors with your graphics card.
