And that's why you had resolution issues. And when paired with a DisplayPort HBR2 system like yours, that means a WD19DC operating in single connector mode would only be able to access 25% of the video bandwidth that an actual WD19TB would be able to access. In that setup, since it is again a USB-C dock rather than a Thunderbolt dock, it operates just like a regular WD19 - not a WD19TB. When used with other systems, even systems that physically allow using both connectors, it operates in single connector mode. It's dual USB-C, but it only actually operates in that mode with (to my knowledge as of this writing) the Precision 7000 Series systems that actually require the dual connection in order to pull enough power to run optimally. But if it's the latter, it's not dual Thunderbolt. And if the 'dual Thunderbolt connection' you're referring to is on the system side, then the only docks it could have been would be the older TB18DC or the newer WD19DC.

I have three new Dell monitors that are all the exact same model with the same max resolution of 2560x1440. The docking station I had before was a K20A with the dual thunderbolt connection (it doesn't say if it was a WD19 or WD19TB) and it never read the proper resolution of my third monitor which is 2560x1440.

I have a Precision 5550 that I have had for about three months for my new job.
