I don't know which dock you're using, but the one I have is connected with a single USB cable - not the HDMI port of my laptop. While I agree that it should be just passing through the data from the graphics card, I'm not sure how much "access" they have to that and there will definitely be a delay between grabbing the graphics chip's framebuffer and the displaylink one. It also has to compress that into a format compatible with the decoder inside the dock itself (I doubt it's a raw RGB stream or anything similar, especially considering that it can support multiple displays, ethernet and USB - not much bandwidth to spare, even on USB3, let alone USB2),which again will have an impact.

I think that much we all accept though, it's the fact that it's outright incompatible with some software that we have issues with. That and the fact that they just don't want to respond.
