Are these kind of displayport to usb-c adapters passive? i.e. no processing done, so no extra input lag added. supposedly these work with the dp-over-usb-c port on my monitor (most adapters don't). www.amazon.co.uk/WJESOG-Displ...

"Power the product itself through USB to ensure stable signal transmission" I'd assume that means it's technically not passive but it's almost certainly not the crummy DisplayLink stuff
