Om het hele 'is een HDMI kabel van een euro van de Action net zo goed als een Monstercable van €80?' debat eens en voor altijd te beslissen hebben onze vrienden van Digital Foundry ze eens grondig vergeleken.

To conclude then, it's fair to say that the advent of HDMI has effectively made the era of stupendously expensive AV cables with dubious-quality claims somewhat obsolete. That £1.50 (including delivery) cable from Amazon will do sterling work for your Xbox 360, PlayStation 3 or media PC - and if it is in some way not up to the job, you'll see it immediately in the form of obtrusive digital artifacting. Only if you're attempting some seriously long connections will a custom cable be required - and even then, the chances are there is an inexpensive version available that will do the job just fine.
As for what comes out of the HDMI port of the HD generation consoles, while the precision and quality offered by the pure digital signal is second to none, bugs or platform holder filtering mean that in many cases we're still one step away from that mythical lossless transfer from video RAM to display.
