Thought I'd add to the conversation here.
I purchased this dock https://www.amazon.com/gp/product/B01FKTZLBS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 about 4 days ago the same day I got my new Spectrex360 13-ac0XX.
Works well, I have it pumping out to three monitors. It charges, uses only 1 USB-C port, and allows for 1 4K display. No lag, sometimes some screen flicker.
Occasionally, when resuming from SLEEP mode monitor orinetation will be scrambled; middle monitor will be OFF and only two sides will be working.
Does the HP Elite TB3 dock allow for waking via the external keyboard or mouse when docked? I cannot wake mine via mouse or keyboard, making it very frustrating to have to keep opening up the laptop, pressing a key, then closing it again on my workstation each time I Wish to wake it.
Any suggestions? Already tried tickboxing "allow this device to wake the computer" in device manager.
Thanks.
