HDMI cable confusion?!?!

Hi, I am looking to get a HDMI cable for my TV. I have been told that because it's digital it doesn't matter what price i pay but then some even on the AV forums have said you should buy an expensive one. I am confused could some one explain this digital thing. I have had a look and this one is cheap

http://www.cclonline.com/product-info.asp?product_id=13611&category_id=182#

but some have recommended the play.com one at £12.99. Could someone clear this up for me i have been spending too long researching this stuff and not time enough studying:thinking: ..... Are there any other places i should be checking....

Kind Regards Ronak

Anyone telling you to buy an expensive HDMI cable doesn't understand how digital technology works. While it is true that analogue equipment benefits from high-quality cables to a point*, with digital, the sound and video is either transferred and decoded 100%, or not at all.

So, aye - buy the cheapest cable you can find. It will transfer the data equally as well as the most expensive cable the AV forum nerds can suggest. Quality will be identical, I can assure you.

actually, I beg to differ! :roll: /\/\

The cable quality will not matter if the length of the cable is around 2-3metres or less. Anything over 6-8 metres and the quality of picture and sound can be degraded as the oxygen affects the cable more. This is where high quality cables should be used , over long distances.

Note that this is only for HDMI cables! I am not too sure about OTHER digital cables!

I forgot to mention that the cable i want will only need to be 1-2 meters in length anyway. I did read that it deteriorates with length as well. Are there any other cables people would recommend apart from the ones above?

Thanks Ronak

I dunno who I'd believe:

the poster above who says cost/quality doesn't matter in digi cables or the people on AV forums where almost everyone who has an opinion on these cables swears by the costlier ones... [they do however point that price is not equal to quality!]

The problem is, you see, the people in the AV Forums are people who have been brought up for years to believe things that are either unprovable as being true, or provable as being complete nonsence. There's an entire culture of audiophile jibberish. These are the people who will tell you that you can improve the sound quality of a CD by running a black marker pen around its outer edge, that you can improve the quality of a hi-fi by never turning it off because leaving it on 'keeps the circuits sharp', and that any of the items on this page will actually make a difference in audio fidelity.

They are correct to a point about cables. As any guitarist will tell you, the longer the cable you use, the less clarity and sharpness you get in the sound. It's a very noticable problem. However, it would be with guitars - the power of the signal they output is negigible, and needs amplified by around 60db to bring it to 'line level'. Every additional 3db represents a doubling of sound volume, so to put that in some sort of scale, that's like comparing the sound levels of a library to a rave. That's why guitar tone is so sensitive to the length of the cable used. With audio equipment, the difference is much less noticable, and as the link above will show you, even a guy who runs a company selling proper high-end cables can't tell the difference between some generic bit of tat made in a Chinese sweatshop from something his company made, and charge several grand for.

Anyway, I may have meandered from my point here (it was supposed to be that audiophiles are full of pish).

With digital signals, they either work or don't. When they don't work, you will observe effects like video corruption, dropped frames, large black areas. Digital cables are of finite length. The spec for HDMI limits them to something relatively tame, like 5m. Beyond that, you may see the digital corruptions described previously, but it is impossible for you to see any other kind of distortion (eg. fringing, snow, diminished contrast) because those are artifacts of poor analogue signal transmission.

So, yes. Buy the cheapest cable.

Not true, there can be differences even at short lengths, especially when some cables are simply not capable of sending 1080p, only 1080i.
