HP nc6220 docking station - what is this port?


I recently picked up an HP Compaq nc6220 and a docking station for it. Looking at the back, I saw a port that I didn't recognize:

It's too small to be a normal DE-9 connector. What is this port? What is it used for?


The docking station has HP product number EN488AA.


Answer



It could be a non standard video output - the image above it is identical to the one I see on S-Video TV outs on laptops (VGA outs would have a symbol like a box with lines on either side).


A little research shows that the manual for what may be another dock refers to a similar port as a monitor stand port.

It is to connect to a HP Monitor Stand (PA507UT), unfortunately documentation for all the models is poor but I did find this Link and this Link
