How to use 2013 iMac as second monitor with Windows 10 PC [duplicate]

Is it at all possible to use my 21.5 inch late 2013 iMac as an external monitor on which I can extend the display of my HP EliteBook 820 G3?

These are the ports that I'm working with on both devices:

21" 2013 iMac ports

HP EliteBook 820 G3 Ports


Solution 1:

This is not possible.

In order to use your iMac as a display (Target Display Mode) , you need to connect it via a Thunderbolt 1 or 2 port. The HP laptop you listed does not have a Thunderbolt port per the technical specifications.
