    Can the Thunderbolt port on the back be used as an video input on Apple's Thunderbolt display. I am seeing mixed reports of this.

    Yes it works as the monitor is basically a Thunderbolt dock with the display panel attached internally via DisplayPort. Just like most Thunderbolt 3 docks have two TB3 ports and either one can be used to connect to the computer, either one of the TB inputs on the Thunderbolt Display will work. Just to be sure I tested it, works fully including all the ports on the back. Out of curiosity why do you ask? Original TB cable damaged?

    Hi elektrobug,

    Yes, I was able to test it myself and it what I am currently using. Thanks!

    I asked because I recently bought a used TBD and while the TB cable is not damaged, it has some wear and tear on it and I didn't want to worsen it since they are a bit of a hassle to change. I figured that it would be best to use an easily changeable cable so if it is damaged over time, it is not a big deal. For the price I paid, I am quite pleased with it thus far. I am hoping to get some years out of it if possible.
