I dont now if this is the correct community to post this. My computer shows signal to the screen when in the os (arch) but when I spam F2 or F12 to get into bios or boot selection it doesnt show anything to the screen. I have an optiplex 3020.

    Already answered but yeah, sounds very likely that you have a GPU, and the display cable isn’t connected to your GPU.

      I’d say the other way around. the bios trying to use the internal GPU and can’t handle the dedicated one.

      Plugging a monitor into the output that’s located on the motherboard would probably work to see the bios
