HDMI Ports must be designed on the 5 Volt DC
Specification on Pin 18 (Orange Wire but wire color differs from some manufacturer). The HDMI Spec allows a tolerance of 0.3 Volt in the spec as per picture below and will sync between 4.7v to 5.3v. Long Cable runs can influence voltage transmission if the source voltage are too low and maximum cable runs will differ from one HDMI port to another due to small HDMI Voltage fluctuations. Using ANY additional contact points such as a HDMI Coupler can reduce HDMI Voltage and results in no signal transmitted. HDMI Couplers in general are used on short distances and on long distances rather use an HDMI Equalizer / Booster.

但d客就好似上面咁講,都係hdmi啫,點解要收咁貴
