HDMI Cable

The HDMI format is essentially a digital version of RGB analog video; the principal signal in an HDMI cable is carried on four shielded twisted pairs (yes, just like a CAT5 cable, but with shielding added), one of which is for red, one for blue, and one for green.

Sync pulses, which tell the display where a line or frame ends or begins, are carried on the blue line. In some cases, rather than RGB video, HDMI carries Y/Pb/Pr "color-difference" video, which represents the same information as RGB but differently conveyed.

The fourth twisted pair carries a digital clock signal, and seven miscellaneous additional conductors carry some signaling and incidental functions. Please find more cables we carry on our website This is Shirley from Linoya. You can add my Skype: chinesecable for talking details.
