Hey, seems like your setup has some quirks. The PC boots fine with the display connected, but when it tries to boot into Unraid without a screen, it just stays idle despite fan power. You’ve got a 5800X GPU, Quadro P4000, 64GB RAM, and a decent PSU—everything looks solid. It might help to check if the display is properly recognized or if there’s any driver issue. Also, ensure the system isn’t overloaded with background tasks that could mimic a server state.
The mobile likely connects to the VGA step of POST. You might bypass it using FastBoot, though this depends on the board. Your Truenas system's BIOS has a setting named "bypass GPU check on boot" that works well. Alternatively, use an HDMI dongle to simulate a display.
