HDMI Difference


Well-known Member
Can someone explain the physical differences between a 1080p HDMI cable - and a "non" 1080P HDMI cable!!

Generally thicker copper, better shielding and more robust construction.

The copper bit allows the signal to go longer distances.
The shielding prevents degredation of the very delicate signal (HDMI i not DIY friendly as some have found out recently!!). Generally multi layer of folil and mesh is needed. This can vary enormously in quality just like coax cable.
Robust construction prevents crack of the metal cores and hole in the shielding when bend (quite common).
