Hello everybody,
as I unerstand the reason of the HDMI cable uses ground in the defferential pairs is because it uses common voltage (LVDS signal with Vcm=1.2V). On the other hand UTP cable does not use ground because the common voltage is 0 (differential volatges -2.5V and 2.5V). Am I right?
Thank you in advance.
