@muso31 You need a WD19TB. That will run dual displays up to 4K 60 Hz each or triple displays up to 2560x1440 each. And it will supply up to 130W to the attached system, which is what you need. The WD19DC is designed for systems that require up to 210W of power, but it only works properly in dual cable mode with systems that have firmware level support for it, which is NOT all systems that have dual USB-C ports. It's designed for the Precision 7000 Series models. But as you found, when working in single cable mode, it works just like the much less expensive WD19, and with the same power limit.
