- maninblac1, on 01/01/2008, -0/+1Wow, the amount of crap in this article is suffocating, let's clear a few things up.
Simple rule, a cable is a cable, end of story, if it's certified to spec, it's certified to spec.
Complex rule, some cables are simply better than others. Case and point 6' monster cable, $150, performs no better than $15 generic cable. Note, it performs equally within spec. Both will pass 1080p signal without issue. However, the monster cable having better quality than the generic cable will also pass a 1440p signal at 15' without issue. The monster cable will also pass a 1080p signal at 50' without issue, while most generic cables at 50' will not.
Lesson learned, if you need to break out of the norm, like stringing a 50' projector run, you could try a generic cable, or not worry about it and buy the quality expensive cable.
One last point, the author implies that digital signals are "all or nothing" in terms of distortion, this is wholy FALSE. Those are bit errors and they happen all the time, on the internet, everywhere you have a communications system. In communications we have what is called BER (Bit Error Rate), for a system well inside specs, the BER is small, such as 1 error in a (insert very large number). In a system that meets spec, it could be something like 1 in a million, like ethernet. Or 1 in 1000 like bluetooth. Just because 1 bit is in error, doesn't mean the other millions of bits aren't, simply in A/V applications, these bit errors are unperceivable unless the occur in a critical location, however most often there is parity in communications systems to ensure that critical locations can at least be verified to be correct.
