HDMI cables are all the same?

[Opti-cal]

Measurements are a really good starting point. However beyond that things get more and more subjective.

The facts are that all signals digital and analogue are susceptible to interference, RFI, resistance, capacitance etc (much less digital of course). Therefore some types of cables must be better at preserving the signal and able to present the amp/DAC/decoder with a stronger/less degraded signal (even if not measurable with our current technology). Of course here there are huge differences between digital and analogue signals but the principal is the same.

Even if the signal that exits from one end is measurably identical to the one that entered (and I completely understand the stance of *if it measures the same it is the same* even if I don't agree) I won't rule out that something could cause the actual picture/sound/information to be presented differently to our eyes/ears.

The way those key senses interact with our brains is still not fully understood.

Anyway I'm getting a bit philosophical/cosmic now but its an interesting debate as ever.

Good post, Chris. Exactly my position on these matters!

Too many folks place their trust in so-called 'experts', rather than in their own eyes or ears.

No you haven't, and it isn't.

I know what I can hear (and see, in reference to picture quality with 'fancy' HDMI cables, which completely flies in the face of your 'evidence'), and I don't give a toss what the videos you've posted supposedly 'prove'. Therefore, please stop presenting your views as fact, or the thread will be closed, as it currently serves no purpose other than to make you feel better about yourself.

Erm excuse me, where have I said or done anything wrong. You won't allow me to put my point over and because I have you will close the thread. These are not my views these are facts but you are not going to let me post them? It might help if you would provide evidence to the contrary or tell my why you feel there is a difference?

Perhaps if I say this, for example there is an easy test pattern for colour gamut, measuring this with a Klein K10 A colorimeter on a tv and then replacing the HDMI on the same TV with a different (more expensive one) will show no difference in colour points right through the range if there was these points would change.

No, your views are as welcome as those of anyone else, as long as you don't try and present them as fact, in an attempt to dismiss the perfectly valid views of those who's opinions clash with your 'facts'.

Do you understand that?

AoS is a staunchly subjectivist forum, therefore staunchly objectivist views aren't welcome here. If you don't get that, then I suggest you find another site to post on where such views are welcome, and where you can post your 'proof videos' until your heart's content. Simples!

Here we concern ourselves more with what people experience, not what science measures.

So let's get this right, as long as I say that you might see a difference that's OK, but if I say and prove in a way some will understand who are not experts in the field as fact then the thread will be closed. You guys are trying to lump video in with audio, audio can be highly subjective but is a different entity all together. Which you are failing to understand.

So-called experts. Kevin Miller, the top man at ISF. David Mackenzie Hollywood and film authoring expert also ISF qualified, Samsung, LG engineers, and rooms full of leading ISF/THX experts.

I'm not failing to understand anything.

What you need to understand is that you're entitled to express any *opinions* you like, and back them up with whatever you like too, as long as you don't use it to dismiss/pooh-pooh the contrary subjective opinions of others, simply because you think you have evidence to prove them wrong, when in reality it isn't conclusive.

Do you get the difference? I hope so, as I'm fast losing patience explaining it. Most of us here pay little attention to what 'experts' think - we just use our own eyes and ears to form our conclusions on any aspect of audio (or video).

Yes, but if what they state contradicts what I've experienced (and tested myself over years), why should I instantly dismiss my own experiences? That's not how a subjectivist thinks! And that's what 90% of this forum is populated with.

If you're going to survive here, you'll need to grasp that fact.

You see that chart mate, any difference in colour it moves, switching HDMI it stays the same. That is not science but cold hard fact and not my view either, it is the law of colour.
