You're using an Asus Prime B450M-A with AMD 5600G and an Emby Server setup. The board supports HDMI, DVI, and VGA ports. Your first monitor is connected via HDMI, but the second one isn't showing up when you try DVI. Checking the BIOS didn't reveal any issues. This motherboard should handle dual monitors if the ports are correctly configured. Make sure both cables are properly inserted and try a different cable or port if possible.
It seems you're checking if a UEFI configuration allows dedicated output while supporting multiple monitors. The referenced document appears to discuss motherboard compatibility and web design for ASUS motherboards. You might also want to verify that your operating system recognizes the second monitor, using commands like xrandr on Linux.
The motherboard is compatible with several monitors. Have you tested using only the DVI port to verify the monitor, cable, and port function? Did you choose a monitor and cable that support DVI-D instead of analog DVI? In Windows, did you adjust display settings to enable multiple monitor support?
Thanks for the feedback. Since you're using Linux, you can execute the suggested command. I'm confident it will work with multiple motherboards. I haven't tested the DVI port alone yet, but since my cable is DVI-HDMI, I'll try it out.
You solved it yourself. Your son used the exact board and processor, but the DVI isn't connecting properly while using HDMI as the primary display.
