I originally bought this type of dock to save space on my desk with my HP Elitebook 840 G6 and expand the display to dual monitors. Worked after the initial setup. Without any changes to the settings, only one display was working the next day after waking up my laptop. On the third day none of the monitors worked. After trying to fix the problem by rebooting, hard booting, and checking the display settings again, I couldn't get any of the monitors to work. I will try to return this dock and buy another one.
