In most home entertainment systems, everything will be grouped together and there won’t be much space between devices. This means that you will only need standard length HDMI cables.

In some situations, however, you will need to use longer HDMI cables. For example, longer cables will be needed when connecting up devices in different rooms, or in different parts of very large or awkwardly-shaped rooms.

You can buy long HDMI cables, but you need to ensure you get those that have built in HDMI equalisers or signal boosters. This is because over long distances, the device (i.e. a DVD player) powering the signal may not be strong enough to supply the monitor (i.e. your TV) with a strong, clear signal. The result of this could be a loss of picture or signal degradation.

Ideally, you should look for long HDMI cables which have special signal boosting qualities, such as extenders, boosters or equalisers. They should also be lab tested to perform at certain speeds and over certain distances, although this is not a legal requirement for manufacturers.

If you still aren’t sure which HDMI cables to buy, make sure you consult an expert on HDMI technology for some sound advice.
