There is no separate "cable" between the display and the motherboard. The "cable" is integral to the display. It's an extension of the flexible PCB on which other electronics is mounted as well. The video is kind of vague about it, but when they are talking about "replacing the cable" they mean replacing the whole thing. The display obviously includes lots of logic that, among other things, stores display's serial number. Same with the sensors mounted on the display.
