HDMI cables for long distances must be of extremely good quality to work and provide a stable, high-quality image over the long distance, i.e. typically 10-15 metres.
For this purpose, we have the following main categories of solutions:
High-quality HDMI copper cable, simply made in an extra high quality, e.g. from Supra Cables.
An active HDMI cable with extension electronics built into the connectors. A value solution that works in most cases, but is directional.
Or cable sets which consist of either a box at each end connected to a standard fibreoptic cable (LC) or a hybrid cable with integrated electronics in the connectors. Note that these are usually directional, where the HDMI signal is converted to work over normal network cables. Note, however, that the cables must be routed as directly as possible, and not through a network switch. Similarly, as high quality a network cable as possible is recommended, i.e. CAT 6a or CAT7 cables, preferably.
Please note that routing an HDMI signal over long distances may be difficult, as the quality of components, cables and noise exposure are crucial factors. Therefore, we recommend contacting us for advice if you are unsure about the project and what cables to use.
