In reviewing monitors, I came upon this Dell monitor, the Dell UltraSharp 27 USB-C Hub Monitor – U2721DE.
With all of the other bells and whistles, it comes with an RJ45 ethernet jack and what appears to be not only a Display Port (IN) but also a Display Port (out). So for the life of me, I cannot figure out why either of those two ports are something I would want?
1. What’s the reason for connecting a monitor to my network?
2. I get the different input options, but why would I be outputting video from my monitor?
I’d love to understand what cases there may be for these options.

This is essentially a Thunderbolt 3 dock built into a monitor.
Most higher end laptops these days have at least 1 Thunderbolt 3 Port. This is an extension of the USB-C specification that allows a LOT of stuff to run off of the one cord. For instance, my work laptop has, in it’s Thunderbolt 3 dock, two HDMI monitors, four USB 2.1 ports, Ethernet, and a headset jack.
This monitor would be like having the dock in the monitor, with that monitor already plugged in. If you run the cord to a laptop, it’ll get those USB ports and the Ethernet port all passed through to it.
