HDMI is basically digital information. Does it make any diffrent?

Check this link. Very good info about it.

Also, please share your experience on the HDMI cable you use. Thanks.

Important note added by admin : Different HDMI cables do not affect the quality of the picture. FACT. Reviews stating that cables produce a 'more natural image' or 'better colours' are complete rubbish

as the first thread in the link stated..

Only difference is the quality of the cable itself i.e. the connectors, built quality but in term of signal, very minimal ..

People already said the signal for digital is 0 or 1. So, not matter what make the HDMI cable, you still received 0 or 1 signal. You think better quality HDMI can produced 0 or 1 in this form: 0 or 1?

So, do you think if machine received better looking 1 or 0

, your picture and audio qualities will be better?

Conclusion, if your HDMI cable can received 0 or 1 signal (mean it is good HDMI cable) or can't received 0 or 1 signal (mean this is defect HDMI cable). That's all, case closed.

So how do you judge the build quality of the cable itself?

Thicker is better? Got braid or not? Metal vs plastic connector plug? Got ferrite bead or not? ...do these things make any practical difference?

I suppose in a very general sense what you say is correct. A lot of people say digital is digital, it is either received or not received. But if you look at the details there are still some slight differences but which I don't fully understand. Have a look at this article: http://www.audioholics.com/education/cable...ble-bench-tests - in particular read about the test equipment and the eye pattern.

Another theory of mine, yes bits are either 0 or 1. But a signal isn't just 1 bit, it's not a case of cannot receive a 0 or 1 signal = complete failure. In one second megabits of signal is passed through the cable, what if the cable is not capable of transmitting all the bits perfectly? What if only 99.9998% are ok and the 0.0002% is not received? How does this affect the audio/video?

Have to wait for expert to answer lo.

I think the only problem is how thier manufacture HDMI cable. Even using cheap material, if you produce the HDMI cable in accordance with proper procedures, the that HDMI cable should have not problem at all. So, even using the expensive materials, if the HDMI cable is produce poorly (the works are not up to standard) that expensive HDMI cable may also fail in future.

thinking about the tramission of all the bits.
If we are copying a excel file from a ext HDD to a PC via a cheapo USB cable. If the USB cable only can transmit 99.9998%, theoretically the excel file is incomplete and some data is missing. But this does not happen even though most people uses regular USB cable.

Thus I still don't understand the expensive HDMIs...

From the cross section view, HDMI cable looks more complex than USB cable. Perhaps HDMI signal also more complex?

Anyway, those expensive branded HDMI cables are relying on audiophile branding to charge more

What is there to understand - just that someone, somewhere is laughing all the way to the bank!

Local? Nah, I suspect they are imported from China.
