I can't get my computer to recognize my second #display. I'm running #Ubuntu 24.04.4 LTS on a Minisforum UM890 Pro with an AMD Ryzen 9 8945HS and Radeonβ„’ 780M Graphics Γ— 16. There are 64GB of memory. The second display is a EVICIV 13.3" EVC-1301 that always worked fine with my Mac Mini and my MacBook. It's connected with a cord that is #Displayport on the PC side and #HDMI on the display side. I also tried it with USB4 to USB4. [EDIT] Problem solved!

@RachelThornSub Hrmm...a few things I can think of to try.

First I would probably start with running "xrandr --listmonitors" to see if the second monitor is even visible to the system. If it's detected but just not enabled, you might just need to enable it. The command would be something like "xrandr --output HDMI-1 --auto" assuming the second monitor shows up as "HDMI-1" in the first command run (replace that with whatever your system says the name of the second display is).

Let me know if that works for you...there are a few other things to be tried if not.

@monkeyninja Apparently it's not visible.
