Supra 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,
1080p and now up to "4k" can be carried by the Supra
HDMI and DVI cables, from sources such as set-top boxes, games consoles
and 5" silver disc players.
In the UK, we now have High Definition TV channels available, from
sources such as Freeview, FreeSat and Sky. Where an external digibox
is used, a good quality HDMI cable is the best way to carry the
HD signals (both video and sound) to your display.
If your display is more than say 2-3 metres away from your digibox,
then it will be necessary to buy a longer cable which has been purpose
designed to incur minimal losses over longer distances (most cheap
cables are only available in short lengths, as they may not work
over longer distances, due to limitations in the production process
- it's easy to design a cable that will only be made into 1 metre
lengths - designing a cable that can be used over 15, 20 or even
30 metres is a lot more difficult.
Various "games consoles" now support HDMI outputs, including
the Sony Playstation and Microsoft XBox. Your supplier
may provide a "standard" quality and length of 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 should
output up to 1080p resolutions, once the film studios start issuing

Are you interested in getting the best quality from your HDMI or
DVI source? Then be aware of the requirements for a good quality
cable. Some cables cannot handle the high bandwidth expected of
them and as such, cheaper lower quality cables may not work properly.
