Dell D6000 - Not recognizing G-Sync, DP-only monitor

[joe_t]

Hi,

I'm using a Dell D6000 with an XPS15 notebook. I have two monitors, a Dell U2715H and Acer XB270HU. The Dell is 1440/60hz. The Acer is 1440/144hz with G-Sync and a single DisplayPort (note that I'm not expecting G-Sync or 144hz to work via the dock).

I have both monitors connected to the dock via DisplayPort, but only the Dell is working -- the Acer is not recognized at all and doesn't show up in Device Manager. I've tried swapping the ports that the monitors are plugged into on the dock and get the same behavior. I'm able to use the Acer (with the same cable) on my desktop.

I've gone through the basic troubleshooting steps as far as uninstalling/reinstalling drivers, and making sure all my laptop's drivers are up-to-date.

I've attached my logs here -- please let me know if there's any other information I can provide.
