With the release of many HDMI enabled equipment, especially the PS3, HDMI cables are becoming more of an importance.
This is to answer the following question most commonly asked:
"Is there a difference between an unbranded £10 HDMI Cable and a branded £100 HDMI Cable".
I've been asked this question many times myself. I thought I would write a short breif guide on ebay to clear some matters up.
The short answer is: NO
An expensive HDMI cable will make NO difference in the quality of your picture or sound.
This is because the way digital signals work. Not getting too technical, digital signals consists of ZEROs and ONEs (0's and 1's) travelling along the cable. A expensive branded cable is not going to make the 0s and 1s any brighter, vivid or sharper. Its just 0s and 1s. It just needs to travel from the source to the destination. Either it gets there or it doesn't.
With digital, you either get a picture or not, theres no quality difference. Think about your Sky digital box. Have you ever got a weak signal, picture fading etc... not really, you either have a picture or you dont.
Digital does not work in the same way analog does. Analog was subject to interferences, weak signals etc and therefore suffered quality loss as a result. A better quality cable may be needed for anlaog, but the principle does not apply to digital.
Mnufacturers are taking advantage of cosumers lack of knowledge about HD or digital technology. they use clever marketing technique for force you to buy their expensive equipment.
I such technique is "You have spent thousands of pounds on a HD Ready LCD TV, HD-DVD/Blu Ray, PS3 or any other electonics, why slimp on a HDMI cable"
Dont be fooled. I suggest you do your own research and discover the facts beforehand. There is a wealth of information on the internet, particularly many internet forums.
