[NAME]  First check the underside label of the dock to confirm it is a WD19TBS, since I remember helping three people in a two-week period who all ordered a WD19TBS but incorrectly received a WD19S. If you do in fact have a TBS, then make sure your system BIOS and TB3 controller firmware are updated, and also update the dock firmware, which would not require a Thunderbolt connection. Then see what Thunderbolt Control Center shows. The dock should be listed there. Lastly, you have to use one of the left-side ports. The right side is only regular USB-C.
I'm having trouble getting my new laptop to push QHD through to my two QHD capable monitors. Using a Bon Elk capable 9 in 1 hub. (can handle 2x4k screens). Using brnad new high quality hdmi cables. Even had a HDMI to DP cable that wasn't even being recognised by the hub. Unfortunately I'm only getting resolutions for max 1080p in display settings. I have even tried disabling the laptop screen. I'm just powering the hub using a fast charge usb-c port. It's running a Quadro T2000 so I know it can high resolution displays. What's the likely problem here? better hub with straight display port plugging in? Thanks in advance.
