Good HDMI cable


Finally a person who used the eye diagram to judge the grade of a cable.

Also....DVI/HDMI systems are very much tolerant to EMI since they run differentially thus reject a significant amount of common mode noise. How do you turn a common mode threat (which is what EMI is in this case) in to differential if it is not done at the receiver via high frequency integration error (Thus the fault of the receiver and not the cable).
 
Personally, I think that the whole argument should have been settled with disc's note of:

"Not to completely bust your balls, but I am an EMI engineer by trade. Amongst a variety of things, we take a very analytical look at cable coupling. Differential digital signals (like those used in HDMI signals) are of the most robust interfaces in use today. I hate to generalize the last two years of our work into a single sentance, but if you're using twisted shielded pair cabling (as almost all HDMI cabling is,) at trivial lengths (<30 meters,) EMI is a nonissue in a typical environment. Bit errors due to attenuation typically become significant above the 10-15 meter lengths (which is why you should use larger gauge wiring for longer runs,) but unless you're laying wires on top of high power generators, EMI really isn't an issue."
