In short

This knowledge base is an organised collection of the LED wall controllers, modules and software you can buy today — together with the manufacturers' official datasheets, manuals and test videos. It is not a catalogue of our own range: we also cover devices we do not sell, because a good decision needs a view of the whole market. Alongside it you will find practical guides on preparing an installation, handing it over and maintaining it.

LED wall knowledge base

Controllers, receiving cards, modules, software and the infrastructure built around them — sorted into categories, with the manufacturer's own documentation, test videos and a plain-English explanation. If you are considering an LED wall, this is where you find out what to ask before you sign.

Practical guides

Long, number-driven pieces on what really decides whether an LED wall project succeeds: from preparation through technical acceptance to day-to-day operation. Each one ends with a printable checklist.

Guide · 15 min read Preparing a LED video wall installation — from the site survey to handover Installing a LED video wall is 80 per cent preparation and 20 per cent fitting. The characteristics of the site — viewing distance, ambient light, wall construction, available electrical capacity — decide what display can go there, not the other way round. The most common causes of delay are not the display but the missing circuit, the unsized support structure, the data run longer than 100 metres and the notification to the local authority that was never made. This guide takes you through the process from the surveyor's laser measure to the trial operation report, with concrete numbers and a printable checklist.

Planned maintenance — a weekly remote status check, quarterly cleaning, an annual electrical inspection — prevents most faults, and a good symptom-cause-remedy list narrows down the rest in minutes. This article works through why a LED video wall deteriorates, what calendar it should be looked after on, what you may and may not put on it, how to measure supply voltage, and gives you a symptom-cause-remedy troubleshooting table for the most common faults. It closes with a printable, itemised list for the annual major service.

At the heart of the design sits one simple calculation: wall size and pixel pitch give you the resolution, and from that, by way of the cabinet resolution, you get the number of gigabit ports and controllers required. On top of that come the refresh rate the application demands (above 3,840 Hz in front of a camera), latency, redundancy and calibration. This article works through the whole sequence of decisions, with three real walls calculated end to end. Read it → Guide · 16 min read Commissioning, setup and technical acceptance — how to check you got what you paid for The quality of a LED video wall is not decided by the catalogue but by what actually appears on the wall on site. This guide works through the sequence of installation and first switch-on, then shows the eight measurements anyone can make at acceptance with no technical qualification, using a phone, a torch and a clamp meter. It also gives the usual contractual tolerances — flatness error, gaps, dead pixel ratio, brightness spread — the numbers for setting the wall up to suit its location, and an itemised list of the documentation without which you should not sign the completion certificate. Read it → Guide · 15 min read Comparing LED video wall quotations — what a quote contains, and what it keeps quiet about The square-metre price of two LED video wall quotations cannot be compared on its own: the LED chip, driver IC, power supply, control system and cabinet behind it can create a three- or fourfold difference at the very same pixel pitch. This guide works through the technical data a serious quotation has to state, the items that are routinely left out (support structure, structural calculations, electrical work, calibration, spare stock), and what you can actually see on a wall where someone has cut corners. It closes with a five-year total cost of ownership worked example and a 20-point question list worth sending in writing to every bidder. The aim is not to rule out the cheapest offer, but to know exactly why it is cheaper. Read it →

For every device you get what it is for, when it is the right choice, what to watch out for, and where the manufacturer's official documentation lives. We do not copy the manufacturers' PDFs onto our own server: the links take you to the manufacturer's own site, in a new window.

Every device in one list

The whole collection is searchable: type in the model or the manufacturer, or filter by category. 141 devices from 48 manufacturers.

How this was put together, and what the links mean

The manufacturer's source comes first

Wherever possible we link to the manufacturer's own manual and datasheet. Where a source does not come from the manufacturer, we mark that at the link.

The document stays with the manufacturer

We do not host or translate the PDFs: the link takes you to the manufacturer's site, in a new window, so you always see the latest version. Documents in other languages are summarised here in English.

This is not a dealer list

The collection includes devices we do not sell. We do not rank or grade manufacturers — we describe what a device can do, and when it is the right fit.

The technical data comes from manufacturer documentation, is indicative only, and the manufacturer may change it without notice. For a specific project, the current manufacturer datasheet always takes precedence.
