I am trying to hook this monitor to a dock. The other monitors are a Macbook laptop and a Asus monitor.

Before our users can assist, they need more data from you =

* What specific dock model?
* List all of the ports on the dock
* List how the MacBook and ASUS monitor are connecting to the dock

The dock model is this Corsair

The Asus monitor is plugged into the Lightning port on both the monitor and the dock. Another lightning cable runs from the Dell monitor via the Display Port on the monitor into a Lightning port on the dock.
The Macbook is connected to the dock via a Lightning cable.
Thanks for your help!

TBT200 TB4 port --> "what cable and conversion" --> to 12 year old U2713HM DP in port?

I am using a Lightning cable. I don't have any "conversion." If you mean what type of converter, I have no converter.

Post a picture of your Lightning cable showing both ends. Or a link to a sales site that shows the cable and both ends.
