Using a USB-C Dock with PD on a Port that Does not Support PD

[seanTX]

I have a ZBook 15 G3 and I’m looking for a dock to replace the HP ZBook Thunderbolt 3 Dock. The new dock needs to support two 4K monitors at 60 Hz, so my understanding is that it needs to be a Thunderbolt dock.

I have three external monitors. Two are 4K and they both have DisplayPort and HDMI connectors. The other one is FHD and has only a DisplayPort connector. The dock I’m considering is the IOGEAR Quantum Dual Mode Thunderbolt 3 Dock Pro, part # GTD737, which has two DisplayPort connectors. I plan to plug one of the 4k monitors directly into the laptop with HDMI, and plug the other two monitors into the dock using DisplayPort.

Will all three of my monitors work, and will it be okay to plug a USB-C dock that supports Power Delivery (PD) into the USB-C port on the ZBook, which does not support PD, while also plugging in my 150 W adapter to power the laptop? I think it should be fine because PD on the dock will identify the USB-C port on the PC as not requesting any power and not supply any, right?

Thanks for any insight!
