Console functioning

I have a number of servers running 15 and 14.  Some are Raspberry Pi 4/5 and some are Mac Minis.  In all cases they are headless servers.  The only connections are power and internet.  When one of them has a problem where I cannot SSH in, I plug in a HDMI console, but nothing ever shows.  It doesn’t recognize the console or attempt to use it.  “echo aaaaa | /dev/console” does not issue an error, but nothing appears on the display.  I have no way of figuring out what has caused the problem.  I have to reboot the machine with the console connected for it to give any information.  Is there a way to make the console work when plugged in after an issue occurs?

From Mac Mini dmesg.boot:

VT(vga): resolution 640x480
vtvga0: <VT VGA driver>

From RPI5 dmesg.boot:
VT(efifb): resolution 1920x1080
