[Edit: Solved] Riddle me this: a monitor works fine via HDMI, but via DP the computer fails to boot and the motherboard beeps five times (indicating a CPU failure) 😵💫

The DP cable works fine with other monitors on the same computer.
This is day 12 of using comrades as tech support.
Edit: I JUST FOUND OUT THE MONITOR HAS A SECOND DP PORT AND THIS ONE WORKS! @refurbishedrefurbisher@lemmy.sdf.org was probably right about the short. You know how new devices come with rubber plugs in their ports to keep dirt out? There was one plug in this monitor that I had never pulled out because I never needed it, and that was this port.
Now I'm on to the next problem with this new computer which is: why are xrandr commands not working and why are two of my monitors set at resolutions higher than their native ones?
easy explanation.
poltergeist.
Damn, that was what I was coming in to comment.
Maybe that's why my bf gave it to me. He did mention he stole it from a Native American burial ground.
It's possible your monitor has some sort of short or other failure somewhere in the DP chain.
That's looking likely.

I'm not sure what you mean by extra features so the answer is probably no. It's a plain 60 Hz monitor, specifically a Dell U2518D if that helps. It was gifted to me used by a rich techbro who used to dick me down after I told him my monitor was stolen.
Thats super odd. Quick googling brought me here on reddit.
Worth a shot since its freeAre there any displayport settings in the bios? Displayport can do some weird power stuff with one of its pins and you might be able to disable that in the bios.
Otherwise you might want to try swapping the cable and/or monitor just to see if that fixes it (borrowing from someone, for example).
It's a new computer so I'm unfamiliar with the BIOS, but I'll check. I use a three monitor setup and I have plenty of cables so I've tried swapping. Right now two are connected via DP and the problem monitor via HDMI.
