Supra HF100 Digital Video cables (2nd generation)
Please note that Supra 2nd generation
HF100 HDMI cables have now been replaced by the 3rd-generation
HF100 cables are still available (for the time being) when terminated
as HDMI<>DVI or DVI<>DVI (single link).
Supra started shipping their "2nd generation"
HDMI & DVI terminated cables in August 2005 and HDMI terminated
versions of the HF100 cables were available in a wide range of
lengths from 0.5m to 15m.
Supra HF100 digital video cables are designed to run at high definition
resolutions. Depending on the source resolution, the length of
the cable and the receiving hardware, resolutions of 720p,
1080i and even 1080p can be carried by the HF100 cable, from
sources such as set-top boxes, games consoles and 5" silver
Suitable set-top boxes that support HDMI include the Sky
HD box as well as the new generation of Freesat
boxes, which includes support for HD broadcasts from both BBC,
ITV as well as other broadcasters. Freeview HD boxes are now available,
but OFCOM only seems to want a limited number of HD channels to
be broadcast.....so for a great HD TV broadcast, your best bet
is via one of the satellite or cable services.....!
The Sony Playstation 3 has a HDMI socket, and likewise,
the Microsoft XBox 360 Elite supports HD at 1080p, via
a HDMI socket on the rear and will be supplied with a HDMI cable
- but YOU may need a longer cable to reach your display or projector.
Likewise, Blu-Ray and HD-DVD players are available which can output
High Definition 1080p resolutions, as long as the film studios
start issuing these discs with native 1080p resolution (i.e. they
are not reliant on a DVD player upscaling a lower quality image
up to 1080p !!).
The new "HF100" cable has been purpose designed to run
at high resolutions such as 720p, 1080i and 1080p even over long
lengths and without problems.
The HF100 HDMI cable is terminated as HDMI to HDMI (in lengths
up to 15 metres)
HDMI v1.2 specifications:
All Supra HF100 cables support the v1.2 specification.
Unofficially, the v1.2 spec supported resolutions up to 1080p,
and all current and previous versions of the HF100 HDMI cables
up to 15 metres in length support 1080p.
HDMI v1.3 specifications:
We have recently received some questions concerning HDMI v1.3a
and whether Supra HF100 HDMI cables match these specifications.
As of Spring 2007, all HF100 HDMI cables up to 8m in length
are v1.3 compliant.
Previously, before spring 2007, only HF100 HDMI cables up to 6m
were v1.3 compliant. This is because, when our 8m HF100 HDMI cables
were tested, it was found that it only just failed to meet the
v1.3 compliance test. As such, it was decided to change the inner
parts of the HDMI connector, because it allowed Supra 8m HF100
HDMI cables to conform to "v1.3" standard. This for
us was important because, after the 1m and 2m length cables, the
8m is our most "requested" length.
These new low resistance connectors have been fitted to all Supra
HF100 HDMI cables since approx Spring 2007.
This should not cause any concern for customers who have bought
HF100 cables before Spring 2007, because all lengths up to 6m,
passed the v1.3 test even before the connector was changed....and
of course, subsequently, since Spring 2007, all cables up to 6m
in length are still compliant....!
Similarly, it has only been within the last 6 months or so, that
"v1.3 compliance" has become "important",
due to the huge number of inferior cables that were being marketed
at very low cost and which, when used at 1080p, were offering
very poor performance....this was because for most people, "HDMI"
is just a generic term for "high definition" and yet,
many of these cables were most definitely, "low definition".
As such, only since May 2008, has the HF100 HDMI packaging been
updated to show which of our cables are v1.3 compliant. So, if
you find a store has sold you a HF100 HDMI cable in any length
less than (or equal to) 6m, then even if it doesn't say it on
the packaging, it is still v1.3 compliant, (as long as it says
it is a Supra HF100 cable on the cable itself).
Likewise, since Spring 2008, all new production of HF100 HDMI
8m cables have been certified as being v1.3 compliant.
Please note: The issue of attenuation (over longer lengths)
affects ALL cable manufacturers to one degree or another -
some offer shorter (than 8 metre) cables while some others are
meeting the v1.3 compliance over much longer lengths by supplying
two (or more) shorter cables and providing an in-line buffer (or
booster amplifier) which receives the incoming signal and then
re-amplifies it to carry the signal over the next cable length.
The HDMI specification allows this "booster" function
as there is a supply voltage on one of the HDMI single lines to
permit active amplification of the transmitted signal.
You should also note that to notice ANY improvement in picture
and/or sound quality (as a result of the v1.3 specification),
EVERY item in the chain, including the encoded signals on the
disc, the player, the cable AND the screen (or projector) MUST
be v1.3 compliant - otherwise, even if one item is NOT v1.3 compliant,
then the picture and sound will run at the v1.2 specification.

HDMI v1.3 specifications - what are they?
The HDMI 1.3 specifications were released in June 2006 and the
1.3a specifications were released in November 2006.
The specifications involve 3 types of connectors:
Type A is the connector currently used on Supra 2nd generation
Type B is a larger connector for dual link operation and
Type C is a smaller connector for mobile devices.
HDMI 1.3 specifications also cover two categories:
Cat 1 is the same specifications for which Supra HF100
HDMI Cables are already tested and approved for (up to 6 metres),
which is good for HD 1080p and supports a clock frequency up to
Cat 2 is NEW and is for a higher resolution and consequently
supports a much higher bandwidth along the cable and supports
a clock frequency of up to 340 MHz...!
Supra HF100 HDMI cables are approved for use as Cat 1 cables
up to and including 8 metres
in length. So far, few (if any) HDMI cables are approved for Cat
What improvements does v1.3 support?
Higher Speed - single link bandwidth can be up to 340 MHz
Deep Color - HDMI 1.3 supports 10-bit, 12-bit and 16-bit
(RGB or YCbCr) color depths (it was up to 8-bit).
Broader color space - HDMI 1.3 adds support for "x.v.Color™"
Lip Sync - HDMI 1.3 incorporates automatic audio synching
capabilities that allows devices to perform this synchronization
automatically with total accuracy.
New HD lossless audio formats - HDMI 1.3 adds additional
support for new lossless compressed digital audio formats Dolby
TrueHD and DTS-HD Master Audio.
Is HDMI v1.3 really necessary?
Here's a link to a great article entitled Is
HDMI v1.3 Really Necessary? which really puts things into
perspective. If you thought HDMI v1.3 is a MUST HAVE, then
for now, you will be sorely disappointed because at present, (and
to the best of our knowledge) there are
NO domestic products that support Deep Color or Lip Sync at present
(Feb 2008). In fact the best you'll get is 1080p
- which is what all Supra HF100 cables support (up to 15 metres
long). So, I wouldn't be too worried about v1.3 for now...!
Supra HF100 Technical Specification
The following list shows the product features for Supra HF100
Digital video cable:
Note that the Supra DVI connectors used are Jenving's own design and are
removable and replaceable and made from die-cast aluminium, which give them good
- 4 screened twisted pairs of solid OFC conductors (with a PE foam insulation
layer) improve the High Frequency response for wide-bandwidth and efficient signal
- Heavy Double layer shielding:
1st layer: Aluminium foil, 2nd layer: Aluminium foil, shield signals from external
influences and prevents the digital signal being radiated into nearby components
or other cables
- 0.8 micron thick 24k gold-plated contacts on connectors deliver long term
- Small form factor cable - diameter only 9.5 mm, enabling cable to be easily
Supra's HDMI connectors are factory fitted and cannot be removed or replaced (especially

Products that need HD-compatible HDMI cables:
The HF100 cable will be of keen interest to Sky HD and Virgin Media V+ (formerly
Telewest TVdrive) subscribers, who have ceiling mounted projectors or flat-panel
screens mounted some distance away from the "tuner/media" box - currently
few other cable companies can manufacture a HDMI.ORG approved HD Ready-compatible
cable that can cope with a 1080i resolution signal over 15 metres distance.
And given that Sky started their HD service on 22nd May 2006 (see
this link) so it's even more important to buy the right cable NOW, to ensure
full compatibility with the new service.
We understand that the single HDMI socket on the rear of the NEW
Sky HD box will carry HD TV signals AND Dolby 5.1 Surround Sound
from the Sky HD box to the TV. If you have a separate AV Receiver
or processor, then a TosLink socket is provided to send the digital
audio to your receiver/processor.
Likewise, the NEW generation of DVD players and recorders also now
feature HDMI sockets, so this is the best way of ensuring high quality
picture and sound (where supported).
Please note: Jenving Technology aB, the manufacturers of Supra branded HDMI cables,
are an official HDMI Adopter company - see
the official list here - for the names of all the adopter companies - you
may be surprised by the absence of many well-known "cable" brand names
- this is because many HDMI cables are made for these companies by third-parties,
unlike Jenving who produce the Supra HF100 cable in their own factory in Sweden,
which ensures better "hands-on" quality control during the production
