In short

A LED video wall never stands on its own: it needs a signal path, a network, a properly sized electrical supply, protection, a support structure and cooling. On most installations it is not the panel but this layer that causes the trouble - the 100 metre copper limit, an undersized circuit breaker, the inrush current at switch-on or a poorly chosen bracket. Here we have set out what each part is for.

Signal transmission, power and mounting

The practical limit of copper Cat6 is 100 metres, but plan with 90. Above that you need a fibre converter — it is not expensive, but if it is missing from the plan you find out on site.
