The quality of an analogue cable can make a big difference. Differences in quality can cause blurred pictures or lack of fidelity in audio.

HDMI is digital, and has to meet the required specification in order to be able to carry the signal. Failing to meet the standard will cause obvious errors in the picure, not subtle blurring or loss of definition.

You can choose whether you like the nice finish, colour, and logo on your cable, though. I've bought cables that look nicer, but they don't make a difference to the picture quality over a cheapie.

(I try and avoid Sony, however, as they tried to rip me off by refusing to honour a guarantee several years ago.)

Please explain to me how if all hdmi cables are the same a cable that outputs @ 1080i will output @ 4k without affecting the quality. It simply cannot, it would have to be upscaled a bit like a scart on a large LED.

1920 x 1080
4096 × 3112

Correct in thinking you will get a picture ....but incorrect in thinking a 1920 x 1080 cable will have the same resolution as 4096 × 3112 rated cable. A simple analogy would be is my Graphic card can output @ 1920 x 1080 but my monitor max output is 4096 × 3112, will it output yes, ill it be as clear as a GPU that outputs @ 4096 × 3112, then no it cannot as it will only stretch the 1920 over 4096.

Audio: Increase in quality = Increase in clarity

If I plug a standard /AllHDMICablesAreTheSame into my TV from my Laptop/PC/Media player can I stream from the internet using only the HDMI cable .... No I cannot, with this cable

... yes you can as it has a dedicated ethernet channel.

i)Yes all HDMI will output digital signals, not all HDMI cables are not rated to output @ 4096 × 3112
ii) The quality of Audio is affected by the quality of cable
iii) Only HDMI with a dedicated Ethernet Channel can stream @ 100MB/s

Em, that's not quite how it works I'm afraid.

Also, and I will look out the reference for this, there was a test done with speaker cable and the cable that "audiophiles" thought was best was actually metal coat hangers.

Cable manufacturers (audio and visual, well at least the really expensive) rarely enter into scientific comparisons, I wonder why that may be...

Yeah I saw the coat hanger experiment which was back @ the begining of 2008

Technology has advanced a bit since then....

The current HDMI specification, version 1.4a, requires all compliant cables to support 3D video, 4K resolution (approximately 4000-by-2000-pixel resolution, or about four times the detail of the current HD standard of 1080p), Ethernet data transmissions, and audio return channels. Each of these features requires more bandwidth, and considerably older HDMI cables (and all older HDMI-equipped devices) rated at HDMI 1.3b or lower can't handle that much bandwidth. For most users, 3D is the only feature they'll use. Ethernet over HDMI is used mostly for networking devices instead ofconnecting viapure Ethernet or Wi-Fi (the methods most consumer electronics products use). Audio return channels are only useful in certain situations with dedicated sound systems.

Stick with your olde HDMI then, if you think it will handle all the new technology which requires more and more bandwidth and the need to transfer @ a higher rate then I am afraid you are sadly mistaken

We aint going to have mass market 4k equipment for 10 years.

edit. That is affordable for the average consumer.

Ah right, the TVs are out. I don't think I'll rush out and buy one though, as I said - what use are all those pixels if there's no CONTENT to fill them?!

haynick

Yawn!!!!!!!!!!!!!!!

Bad analogy
"A simple analogy would be is my Graphic card can output @ 1920 x 1080 but my monitor max output is 4096 × 3112, will it output yes, ill it be as clear as a GPU that outputs @ 4096 × 3112, then no it cannot as it will only stretch the 1920 over 4096."
That would be the restriction/output limit of the graphics card, not the cable from the card to the monitor

Yes when I output from my pc with an anlogue vga cable it gets ghosting. Using the digital dvi it doesn't. It's digital 1's and 0's, works or doesn't.

What does happen with digital signals is that interference cause's some of those 1's and 0's to go missing or messed up. You see this with your broadnad over copper cables. The further from the exchange the slower the speed you get. This is to combat the loss of data, rather than it just not working they slow the speed so they can use some of the bandwidth to correct the errors.

I doubt you really get this from such a short run of cable. If the higher resolution is at a point where cheap wire doesn't work but expensive does. Then I'd imagine there would be a new kind of connection not just higher grade certfied wire.

I'm hanging on for a wire to connected my movie player to a full 3d holographic projection system though... after I get my hoverboard obviously.
