Describe a "display port" socket, please, Felix.  If you've the time.

This db15 to hdmi cable had been working quite normally for about 2 
years, but the monitor
was not plugged into  the ups the Dell was, and we had some noisy 
weather in the night
Tuesday night, no video the next morning. I live alone now, and I did 
not get up in the night to
move any cables.

Now I have a rock64, 4GB V2, running octoprint, better display than that 
AOC was by far.
And its all plugged into the same ups now.

However, that means cura has to run on this machine to generate the 
gcode octoprint feeds
the printers with. But cura can't see a dotted directory, so there's a 
third step between my ideas
in OpenSCAD, and getting the code into octoprints input buffer.

The dells SSD should be pulled, a startech usb3 to sata adapter added 
and put on the rock64
for a work disk. The 64GB pnc its booting from now is not noted for 
either speed or longevity.

Thank you, Felix,  take care and stay well please.

Cheers, Gene Heskett.
