A good article.
It's important to stress that almost all HDMI cables that are short in length (around 15 feet or shorter) will almost certainly be able to handle 8-bit 1080p content, which is the highest signal quality in common use today. In other words, if all you're doing is connecting your DVD player to your TV, you're almost certainly fine with almost any HDMI cable.
This article's warning mostly applies to in-wall installations, or other installations where it would be difficult and/or expensive to replace the existing cable run. Only in that sort of situation are you likely to be using a longer than 15 foot length of HDMI cable and only in that sort of situation would it be likely that you could not easily and inexpensively replace the cable if there ever comes a time when far greater bandwidth is being used by common signals.
Thankfully, even if you are in need of a long length HDMI cable and one that is already fully tested and certified to comply with bandwidth usage far in excess of today's common signals, you do NOT have to pay an expensive price!
Both monoprice.com and bluejeanscable.com offer HDMI 1.3 Category 2 tested and certified cables in both short and long lengths for very reasonable prices.
The obvious and worst offender of spreading misinformation and charging far higher than necessary prices is Monster Cable. Much like Bose, Monster Cable's business and profits depend entirely upon misinforming the mass market and convincing the mass market through advertising that their products are superior to others and worth their extremely high margin prices. Retailers gladly go along with this despicable practice because the margins allow for greater retailer profits as well.
I'm fine with profits. In fact, I applaud Monster Cable and Bose because they are exceptionally good businesses in the sense that they make tremendous profit. What I object to is the amoral and dishonest aspect of achieving these profits through misinformation and lies.
Sadly though, the responsibility lies with consumers to uncover instances where they are being ripped off. It is not Monster Cable's nor Bose's job to conduct business in a fair and honest manner. It is consumers' job to demand fairness and honesty. And the only way to make that demand is through use of the open market. In other words, stop buying over-priced, under-performing products and instead, buy fairly priced, honestly performing products.
Consumer education is the key, which is why Monster Cable and Bose spend so much money on advertising. Advertising is nothing more than "education" for the mass market, but when that advertising is spreading misinformation, "education" becomes "propaganda".
