Just looking for a new hdmi cable and come across this!

http://cgi.ebay.co.uk/QED-Performanc...item588425846a

 

It is 20 metres long.

 

No looks like thats the price just googled it! QED is a high end BRITISH make but cant see that there will be much difference between this and a no name make, well not in viewing terms to the layman

 

That'll be why then, i must of missed that was just in shock by the price at a quick glance

 

Pretty sure mine made by them!

 

ive got a 20m one in the loft, bought it for a projector project i was going to do, but never got round to. its just black tho, not purple, and didn't cost nearly as much as that!

 

i paid £78 for my HDMI Lead

had a tescos one before the difference is like night and day!!

 

Got my sky hd fitted today, swapped over the cheap cable that comes with it to the £55 cable I've got for my PS3, didn't notice any difference lol

 

not only do consumer tests prove theres no difference between cheap and expensive items, but even science proves it! its a digital signal of 1's and 0's, it isnt affected whether its a 2quid cable or a 200quid cable! lol

asda specials for me all the way

 

Yeh

They had it on Radio 1 a while ago as like a consumer thing- until you realise its digital signals and all 1/0's so all the gold terminal spunk filled bollocks is just a load of shit.

 

yep its about £50 more expensive than from hifi shops

 

I once paid £125 for a pair of 0.8 phono leeds when i was 19.

speaker wire was £24 per meter too. 8 meters worth too :0(still got the reciept)

 

Absolutely impossible. HDMI is a digital cable, and as such there can be no degradation on picture or sound. It either works or it doesn't. Simple as that. All it passes through is 1's and 0's; it cannot affect the 1's or the 0's; make them better or worse. It can only pass them through 100% or 0%

 

There is also corrective factors as well so even if the signal does get distorted through transmission they are corrected at the receiver end so the distortion or interference would have to be that of an electric pylon to distort a 1 to a 0 or vice versa. Isn't an analogue signal that is incredibly susceptible to distortion and interference.

 

The old placebo effect. It cost more, therefore it must do a better job.

 

really?

 

i did not pay that for my tv let alone a cable

 

You'd be gutted if your cat/dog chewed through that fucker.

 

when i used to fit sky hd people used to ask me if i would fit fancy leads for em while i was there, i told em all to take em back packaged
weirdly we (the electricals co work (i do sat and aerials) for now sell fuckin hundreds up to £100 a time)

 

Most expensive HDMI cable I bought cost £6. And that's only cos Tesco had run out of the £4.99 Tesco Value ones and I couldn't be arsed to wait a week for a 99p one from ebay!

 

If thats the truth........................



Then

 

i see all the passionford electrical experts are on again
my sky hdmi lead is like this http://cgi.ebay.co.uk/QED-Performanc...item5ad137db56

well i havent got the old Tescos HDMI lead anymore think i must have chucked it away but on my 60" Plasma i could clearly see the difference in picture .

 

i agree with you roosie i got a cheap one off ebay from play .com (cost £12)& the picture was shit it had green tint to every thing then i bought one from curry,s it was a ixos 10mtr(cost £80) & the pic is stunning .so regardless what all the doubters say there is a difference & you get what you pay for when the length is long .

 

Not dissing your statement but that really pisses me off as i see so many comments on here ie:

"Its cheap for a Reason"
"Its only Cheap because its Crap"
"you get what you pay for"
"Why Pay Twice"

 

lol......you crack on then lads with your "Pub talk" HDMi cables........lol

 

definately no difference in these leads, I got one of the monster cables and it was worse than 99p job, simple reason been cable is too heavy and it kept pulling itself out of the receiver, using cheapo ones now and picture is perfect.

 

As said above.. Its digital so would make no difference at all. I went from £40 HDMI to £4.99 Tesco value ones and noticed no difference at all.

Checked with a mate that does AV installs and he said no difference would be seen.

 

Here is a quote about the quality of HDMi cables from someone in the know.....

Dr Eric Chowanietz, Principle Lecturer in Media Technology at De Montfort University, believes there is little to support the claims made for pricier models.He said: "You wouldn't buy a more expensive printer cable and expect to print higher quality documents.
"The document quality depends on the printer and it is much the same with a digital system."

 

Or this one........................


"Question: Is there any difference between a cheap (i.e. $10 HDMI cable) and an expensive (i.e. $150 HDMI cable)???"

I have an EE degree. I work as a broadcast engineer. I live and breath digital and analog signals every day. So yes, you could say I'm qualified to give the answer to this question...

That answer is, "No, an expensive HDMI cable will make NO difference in the quality of your picture OR sound"

I'll give you the more complex reason first, then an analogy... Hopefully one will make sense... If you don't want all the real technical stuff, just skip down to B for a real simple explaination...

A) Wires send electrical signals... Plain and simple. Anything sent over a wire is ultimately just a voltage/current applied to that cable. Let's say we're talking about an analog video signal that's 1 volt peak to peak... In other words, measuring from the LOWEST voltage to the HIGHEST voltage will give a result of 1 volt... With an analog signal you have "slices" of time that are "lines" of signal... It's too complex to go into here, but basically you have a "front porch" which is known as the "setup"... This is what helps your tv "lock onto" and sets the "black level" for the signal. After that you've got each line of the image (455 half cycles per line). Again I won't go into how chromanance (color information) and luminance (picture or brightness information) is combined, seperated, etc.. It's too complex for this discussion, but irregardless, just know that following that porch you've got all the lines of the picture (and some that don't show up on the picture... these carry closed captioning, test signals, etc...). All of these "lines" of information when you look at them on a scope look like this...


That waveform is all of that information in analog form... In other words, if you look at one VERY SMALL timeslice of that waveform, the EXACT position of the form (i.e. what voltage is present) represents what information is at that position...

Because of this, it's VERY EASY for other radiated signals to get "mixed in" with that information. When this happens, the more "noise" you get mixed into the signal, the more degraded the picture will be... You'll start to get snow, lines, weird colors, etc... Because "information" is getting into the waveform that doesn't belong there...

With digital however, (i.e. the signal sent over an HDMI cable), the information is encoded differently... At it's lowest level, it's nothing but a string of bits... In other words, each signal is either ON or OFF... It doesn't care if a particular timeslice is 4.323 volts or 4.927 volts... It's just ON... See on the right side here, the "square wave" pattern?


That's what a digital signal looks like... For each "slice" of the signal, the "bit" is either on (if the signal is high) or off (if it's low)...

Because of that, even if you mix some noise, or even a LOT of noise into the signal, the bit will STILL be on or off... It doesn't matter...


Now, for a slightly easier to understand analogy...

B) Think of it this way... Let's say you have a ladder with 200 steps on it... An "analog" signal represent information by WHICH step the person is on at a certain time. As you move further and further away (get "noise or interference in the signal), it's very easy to start making mistakes... For example, if the person is on the 101st step, you might say he's on 102nd, or as you get further away, you might start making more and more mistakes... At some point you won't know if the person is on the 13th step or the 50th step....

NOW... In a digital signal, we don't care if he's on the 13th or 14th or 15th step... All we care about is rather he's at the TOP or the BOTTOM... So now, as we back you up further and further (introduce more noise), you might have no idea what STEP he's on, but you'll STILL be able to tell if he's a "1" or a "0"...

THIS is why digital signals aren't affected by cheaper cables, etc... Now eventually if you keep moving further and further back, there may come a point where you can no longer tell if he's up or down... But the good news is, digital signals don't "guess"... If they SEE the signal, they work... If they DON'T, they DON'T.. LOL

So if anyone ever tells you they can "see the difference" between HDMI cables, etc... You can knowingly laugh to yourself and think about how much money the poor sole wasted on something that was pointless.


Now, I've seen others say that they make a difference in audio... ALL audio carried over HDMI is STILL in digital format... So again, since it's a digital signal, it will not make ANY difference at all....

I've also seen various posts in regards to things like "Make sure you get a v1.3 cable"... The various HDMI versions determine the capabilities of the DEVICES on either end of that cable (most of the HDMI versions (other then 1.0 to 1.1) have to do with AUDIO and how many channels / type of audio are carried...) Because of this, the cable itself is NO DIFFERENT... It's just marketing that some companies charge more for a "v1.3" cable then a "v1.1" cable, etc... The cables themselves will work now and WELL into the future for any other HDMI versions that come along the way....

So there you have it... Hopefully it's clear enough to understand and hopefully it will help prevent a few posts...

 

Which is pretty much just a very long winded way of saying what I already said

But still true. You wouldn't pay £78 for a USB cable would you? Of course not!

It's the same with optical cables - they either work or not. Simple.

 

I just loved the whole "Ladder" section..........i thought it was a Tarantino script at one point

Im just trying to find some bags of fresh air for Roosie and Andy to buy......

 

i got my 7 metre cable off ebay for £3 and its spot on there is no way i would pay that

 

come on then clever clogs tell me why the cheap one caused green shadowing & the ixos one didnt

 

LOL

But seriously, on a serious note, the ONLY reason to buy a cable that costs more than 99p is purely for a better MADE cable. One that costs a tenner might last longer than one that costs a quid. But then, this is only going to matter if you are constantly plugging and unplugging it. If you're gonna plug it in and leave it, then it won't make a difference!

 

Go and buy a £9.99 one from Currys tomorrow and see what happens......

 

Id say it wasnt making quite right, with one of mine if its not all the way home for some reason I get a red tint to the image.

 

i found no difference when i changed from my £30 cable to my 99p cable

ok, so my cables are only 1m and 2 m in length but there is NO differene

in fact, if it were "onn show" then i'd have the flash cable on display, but seeing as it's going through the pipe in the wall, it's hidden to no need know i don't keep up with the jones's

 

M&M
-mugs and money

 

Well in this case you certainly didnt get what you paid for. £78 for an HDMI cable. you got mugged. You wouldnt pay twice for it and its not cheap, nor is it cheap for a reason. It expenisve for a reason - because people buy them thinking they are better.

 

Good bit of advice that
