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

Lol..you go ahead and test and let us know. I aint going there without any protective gear laugh.gif

Was at a few big radar dish and you can hear its high pitch sound which the radiation meter can pick up a lot of wave coming through it..go near those things is like putting yourself in a microwave oven and bake laugh.gif

I aint ready to fight cancers yet..still wanna enjoy my hifi a bit longer brows.gif

Well, my take is this. Usually those affordable hdmi cables will cut corners to save cost so their margin is more (this is the norm right?  brows.gif ) and while those audiophile HDMI will usually give you the best possible quality as required by HDMI corp standard.

Look at this one :

[attachmentid=2700036]

This is where the difference between a good quality and a poor quality HDMI cable. Then the purity of the cable material and shielding plays certain part too. However, by meant good quality doesnt meant it has to be expensive as well neither is expensive is always good. I'll always go for the certified HDMI adopters/manufacturers products when it comes to HDMI cables to be safe. And the longer they're in the business, the better it's as they're not found to be cutting corner when being given the license to manufacture the HDMI cables for OEM/mass markets.

The list can be found here :

http://www.hdmi.org/learningcenter/adopters_founders.aspx

Surprisingly most of the audiophile brands arent listed as the manufacturers/adopters which means they're OEM from one of these listed manufacturers instead  laugh.gif

I personally ripped apart a few HDMI cables from cheap to decent audiophile brands due to malfunctioning and were surprised at each post mortem investigation and I'll am now a firm believer in good quality HDMI cables at very affordable price  brows.gif

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

If it's not stated, usually it's v1.3 unless it's stated.

This is eye opener..pls..continue..we want to know more  brows.gif

Finally some one understand what am I talking about. Yes it is all about the EYE Opener. The digital signals are like girls eye, big is good. Refer to following picture:

Over the time, all the cable will get de-rated and resulting the transmission signals are not good as compared to new one. If the cable is not good enough, then the transferred data will get corrupted and in the worst case, the cable is not able to link up 2 devices.

Actually to be effected by noise, it does not need to placed at electromagnetically environment, just put your cable next to your power cord. However, most of the high speed signals such as HDMI will not have effect on those noise even at electromagnetically environment. This is because HDMI is using differential pair of signals and they are able to cancel the noise. Furthermore HDMI is using 8b/10b encoding and therefore it can recover the incorrect bit.

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

I can confirm it'll work except if you're trying to ARC your TV audio to your receive then it wont work. The Ethernet feature so far is quite useless as no device can take advantage of it..yet.

Meanwhile, if your v1.3 cable is shorter than 5m, it'll also pass 3D signal without much problem. Try and see if you got frame drop out problem not, like blinking of the scenes. If there's, the EYE isnt wide enough to pass through the required signal at all time then it's time for you to change the cable.

Most v1.3 cables are either AWG30 or AWG28, rarely got AWG26 while v1.4 starts with AWG28 for short length up to 5m and AWG26 at least for there onward. Audiophile HDMI usually is at least AWG26 to some is AWG24 all the way brows.gif

The rule of the thumb is 10m before repeaters or quality of cable comes into play.

That's textbook rule. Real life HDMI has 30awg, 28awg, 26awg, 24awg. It's better to limit to 5m than 10m which your picture quality can suffer due to other factors such as connector, gauge and contact point soldering.

Hi guys. Please point me in the right direction if this is the wrong place to post. It's a basic question, and as I'm new to this home entertainment stuff, will like to seek for your input.

It's about the Full HD 1080p feature. Let's say I have a movie of that definition and I load it onto a USB stick and have a TV set, which supports Full HD 1080p, play it from the USB stick, will it be able to produce Full HD 1080p or just SD?

Is it a must for a HDMI cable be used, be it from a HD player or something else, in order for the TV set to produce the Full HD 1080p picture quality?

Thanking you guys in advance. smile.gif

Actually any cheapo high speed cables will do just fine, even for 1080p 3D Blu-ray.

HDMI cable quality will be a concern if your using it for digital theaters or projectors like ;

3840 × 2160p (Quad HD) at 24 Hz/25 Hz/30 Hz or 4096 × 2160p at 24 Hz


why need 10m cables?

It depends how you rip the contents to your USB stick. Likely you'll get the SD unless you use certain ripping software/machine.

Yes, all consumer electronics for it to deal with full 1080p HD version, only the HDMI can "handle" the signal so the content is "protected". Of course, exception to this is where the player/recorder is built to rip HD content from the disc to the HDD within the unit but not from one device to another.

Actually that's the real world guide. There was a long article and test on this - cannot remember the source, its probably WhatHifi or Audioholics or BlueJeans.

So many choices for HDMI nowadays. Get one that has thicker cable, well built with gold plated connectors.

hi experts,

I own a HD plasma TV (1024x768), and plan to get a bluray player after this, i suppose all bluray player is supporting full HD (1920x1080) rite, so the bluray movie quality will get some sort of 'down-convert' to HD scale and send to my TV rite?

Then the question comes, for this application do I really need a HDMI v1.4 cable? Or v1.3 will do the job well?? I not really sure whether my plasma TV support ARC feature (It's a Samsung Plasma PS51E451 model).

v1.3 cable can get below rm50, but I think v1.4 cable close to rm100?

If I am using v1.4 cable, what sort of advantages do I get from this? Assuming in future I will use the same HDMI cable to plug from my laptop to TV.

Lol..you may try 10m. I have tried even at 5m, some HDMI cables already struggling with 1080p 3D..
