RE: Re: long HDMI 1.4 cable problems

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

It's just a labelling thing - HDMI 1.4 relates to the features of the
HDMI
chipsets in hardware and has nothing to do with cabling. The change from
HDMI 1.3 to 1.4 had no impact on the cabling if it was already high-speed
(10.2Gb/s) rated, so in effect your 1.3 cable can still carry 3D, 4k2k etc.
However your HDMI 1.3 AV receiver will not pass 3D.



If you want Ethernet over HDMI then look for a high speed cable with
Ethernet, however so far there is little or no hardware that supports this
cable feature so also make sure you've got a Cat5e alongside for Ethernet
duties.



I would suggest that cables marked HDMI 1.4 compatible are more than likely
not to have been tested, as any cable manufacturer who follows HDMI.Org
certification will have their cables marked as one of four options
(ignoring
the automotive cable standard); Standard HDMI, Standard HDMI with Ethernet,
High Speed HDMI, High Speed HDMI with Ethernet. HDMI cable & equipment
testing is an expensive business, the test equipment costs a small fortune
and there are only a few companies carrying out independent testing &
certification.



For short cable runs you will find that the cable is not much of an issue
unless very poorly made, however start pushing the distance in excess of 5m
and you can start to run into issues when aiming for 1080P video, let alone
3D. 15m is one the edge of limits for 1080p 3D based on my cable
experiences
unless you have good quality cables and even then you may need to look at
adding a booster/repeater at the display (or use an even more expensive
"active" cable that includes similar electronics) to help clean
up the
signal.

Surely in the case of HDMI 1.4 - it does explicitly impact the cable. The
Cable needs to support the additional Ethernet Connectivity channel
introduced.

Any increase in bandwidth (such as the increase to 4k2k resolution for 1.4)
will place greater demands on data cabling and expose cheaper cable
manufacture or shielding. 10.2Gb/s is a not insignificant bandwidth on
copper cable. So again "1.4 support" should imply the shielding
etc has been
tested at those higher data rates.

You should be looking for a high-speed HDMI cable, the numbering scheme
(1.4
etc) relates to features of the HDMI chipset and has nothing to do with
cables. This is rated to achieve 10.2Gb/s which covers 3D, full HD audio
and
4k2k resolution for future proofing.

If you are looking for reliability then I would suggest going for a branded
cable providing costs are not too horrific, or look for a HDMI booster to
clean up the signal at the display. Cheap unbranded cables are unlikely to
have any testing so their performance is likely to be hit and miss. If you
want to talk to a company who supply good quality HDMI equipment and who
can
give excellent support then speak to Joe or John at The Media Factory - I
use their Octava HD-Base-T extenders in all of my installs now as they are
100% reliable and work over distances of upto 100m, and all over a single
good quality Cat5e cable. For "proper" HDMI cables I now either
use
Wireworld high-speed flat cables or Sanus highly flexible high-speed
cables.
However I would only go upto 5m with such a cable, after that I prefer to
use baluns with Cat5e.

I've used 15m eBay "cheapies" at 1080p without issues ... but not
at 3D.
