Is there an actual graphics processing system inside the dock? For docks with two or three HDMI outputs, shouldn’t reviews be focusing on the performance of the internal GPU system? Because it’s something I’ve not noticed in reviews if that’s the case.
No the docks don’t have any video processing capability, they either convert the usb-c to video, or they have a driver like DisplayLink. In the case of Dell, the usb-c docks are limited to one 2k or greater monitor at a time, so you can have a 2k and 1080p, but not 2 x 2k or a 2k and a 4K… the Thunderbolt version of the same dock has no such limitation
