I have recently purchased a Dell 5410 and paired it with a WD19DCS dock and am attempting to run standard monitors with HDMI inputs. I have purchased 2 x aLogic DisplayPort to HDMI cables to get the video signal from the dock to the monitors but these cable do not seem to work. I have researched the aLogic cables I purchased and on their support page, there is a reference to ensuring that "DP-ALT" mode is turned on and that the dock can run it.

First question, is the WD19DCS dock capable of running in DP-ALT mode?

Second question, if so, how do I turn it on?

Thanks team...!
