although they are electrically compatible, HDMI seems to support more video mode

so by paying 30x more, does it make the cable more superior than other?

RM10K for how many meter? shocking.gif I am from kampung, I want to see see such cable, must be made out of gold brows.gif

for comparison, most expensive HDMI cable in the world will cost you US$1K/m

And if you think your super size Plasma TV is expensive, you haven't seen what some speaker can cost. How about RM200K sounded to you?

plasma TVs have been cheap in recent years

definitely there are difference between 2 HDMI cable....

I did some research online and there are only 2 possibility that this would happen:

1. The voltage drop from 1 end to the other end is too great therefore is may have passed the tolerance of the projector (it may be digital but copper cable send the 0 and 1 using electrical pulse)

2. signal lost. too much missing data to the stage that the algorithm is not able to retrieve the missing 0 and 1. 

well....sometimes if the algorithm replaces the missing 0 and 1 with the wrong code then there will be error in the picture like Andrewtst stated in the previous page.....

no there is no error correction scheme in the video stream, you will get garbage in garbage out

cable construction is the key to preserving the ones and zeros, such as proper shielding, tighter tolerance in the cable twist...

I got free 1.5m HDMI cable come with media player, max video mode is 720p

change to tesco's RM9.90 3m technika brand HDMI, 1080p no problem

I suspect the failure of the first cable to carry higher speed data is because of insufficient number of wire pair twist inside the HDMI cable

test using 720p, if 720p is working OK then HDMI cable may be not up to spec

I have tried a few hdmi cable recently. I can see the different. Really don't understand why it is different, theoretically it shouldn't as hdmi cable is transmitting digital signal.

wire pair twist is critical in maintaining square wave form shape for high speed digital data transmission, the more twist there is in the wires, the more it can reject noise and therefore transfer digital data better

what version is that ?  biggrin.gif

did not see version number printed on the cable, is that important?

if the cable can work at 1080p, then it is high speed cable

Nope, you're not correct. High speed term is used in the v1.4 hdmi cable which is categorised into a few category.

Read it here :

http://www.hdmi.org/consumer/buying_guide.aspx

ok these quotes are from HDMI website:
QUOTE
When it comes to selecting a cable, the HDMI version number is never relevant. There is no such thing as a “Version 1.4 cable” or “HDMI 1.3 cable” - these terms are solely the creation of manufacturers’ marketing efforts. Cables are instead rated by their performance capabilities. There are five HDMI cable types to choose from:

    Standard HDMI Cable - Designed to handle most home applications, the Standard HDMI Cable can reliably transmit 1080i or 720p video plus surround audio.
    Standard HDMI Cable with Ethernet - Same baseline performance as the Standard HDMI Cable, plus a dedicated Ethernet channel for Internet connection sharing and device networking.
    Standard Automotive HDMI Cable - Designed for internal cabling of motor vehicles equipped with onboard HD video systems.
    High Speed HDMI Cable - Designed to handle video resolutions of 1080p and beyond, including advanced display technologies like 3D and 4K.


so which part I said is not correct?

Mr Tiger, perhaps the better way to put it is your statement isnt accurate  laugh.gif

The older HDMI cables from v1.1 onwards also can pass 1080p signal. In fact every short enough HDMI cable can pass 1080p signal without problem. So would that meant they're all High Speed as labelled in v1.4 standard?

yes, if the cables, short or long or fat or skinny or branded or pirated or beautiful or ugly, certified at high speed test, then they are high speed cable. what other tests do you need for the cable to qualified as high speede cable? Brand name may be?

HDMI is smart to ditch version number on cable, after all cables are bunch of copper wire, version number should only applied on devices based on their features

may be to test cable's bit error rate in a electromagnetically noisy environment such as next to a GSM transmission tower, to prove that it got adequate shielding, Guinea pig? icon_rolleyes.gif

most of the HDMI cable nowdays are high speed , but there is 2 version .. v1.3 and v1.4 .. but if rm9.90 sure its v1.3  whistling.gif

free bundled HDMI cable come with media player is usually standard speed type

I do not have HDMI v1.4 device, will test my"v1.3" cable if it can work on v1.4 devices in the future cool.gif
