My Mac mini just rebooted because of a kernel panic. What does this mean?

Can't tell all that much from Panic reports anymore, but something to do with your Display, could be a munged install, bad hardware, bad cable, eventhe Monitor itself.

Are you using any 3rd party Display software?

In Disk Utility>View, select Show all Devices, highlight the top left entry.

Run Disk First Aid on all items in the left panel, from top down.

Are you running any VPN, Anti-Virus, or Cleaning apps?

We need to see what all is running, a report from this will not display any personal info...
