They really are, especially for hdmi and dvi cables which transmit digitally. That means no signal-to-noise ratio, just noise margin. If your margin is enough to pass the bits, that's all that matters. Someone on the net even found out that dirt cheap cat-5 cable works fine for hdmi, as long as you put the proper connectors at each end.
When USB-1 (max 12Mb/s) came out, some dealers were selling premium cables and all their advertising made people think they needed those special cables, and if a cheap cable worked, it was probably right on the edge. Then USB-2 (max 480Mb/s) came out and the same cheap cables STILL worked.
Sorry, you brought up one of my touchy subjects.
