@Jecole215  All of those systems have USB-C ports that support video output and charging the system, so you've got a ton of options.  Dell's own WD19 would work fine, and based on the models you have, you'd be fine with the regular WD19 130W w/ 90W passthrough, no need for the WD19 180W w/ 130W passthrough.  You'd be able to run dual displays up to 1920x1200 each or a single display up to 2560x1600 60 Hz (or 4K but only at 30 Hz).  There's also the WD19TB that can tap into Thunderbolt 3 if the system supports it, which raises display options up to dual displays up to 4K 60 Hz each or triple displays up to 2560x1600 each.  The WD19TB is also backward compatible with non-Thunderbolt, regular USB-C devices, but only at reduced functionality equivalent to a WD19, so if you had a display setup that required Thunderbolt, that wouldn't work so well when using a non-Thunderbolt system.  And Thunderbolt 3 is optional on some of the models you listed, so your specific systems may or may not have it.
