Configured via Wall Designer over USB or network, then disconnect — the wall keeps running without a connected computer
Gen-lock and frame-lock support for tear-free display across every output
Frequently Asked Questions
Do I need a PC connected permanently?
No — that's the point of the standalone range. Configure the unit once using Wall Designer over USB or the network, then the controller runs independently; a PC is only needed again if the layout changes.
How do I choose between HX4, FX4 and FX4HDR/FX4SDI?
HX4 is the simplest and lowest-cost option for a single 4K source fanned out to four HD outputs. The FX4 family adds multi-input flexibility — FX4HDR for HDR10/HLG sources, FX4SDI for SDI/DisplayPort/HDMI inputs — where the deployment needs to switch between more than one live source.
What's the maximum input resolution?
Varies by model — check the individual product's Input Surface spec rather than assuming; it's not the same figure across every unit in the range.
Can outputs overlap or replicate each other?
Yes on the FX4 family — each output can take its input from any region of the source image, regions can overlap so one output replicates another, and any creative splice of the source material is possible.
