Solution 08 · LED & LCD video walls

A bigger picture, planned down to the pixel.

Bring your content onto a readable, consistent display surface. We plan the screen, processing, structure, power and service access together, from a lobby LED wall to a tiled LCD display with separate source windows.

Fig. 08.0 — LED & LCD video walls
01Overview

Start with the content and the people viewing it.

A welcome film, a presentation and a detailed dashboard place different demands on a wall. The closest viewer helps determine pixel pitch; the farthest viewer and the smallest important detail help determine image size. We review both before selecting the display technology.

The physical surface and the system that composes the image are separate decisions. LED cabinets determine size and native resolution; their sending controller maps video to the receiving electronics. An LCD wall has visible seams and needs an output for each panel. A compositor adds source windows and layouts when the brief requires them.

These three reference configurations describe intended functions and example quantities. They are starting points for project design, not fixed purchase packages or completed installations. Component compatibility and complete-system performance still require project verification.

Intended outcomes: content sized for its viewers; a surface that can be serviced; documented source routes and operating settings.

For operator roles, KVM and shared operational workflows, see Control rooms & command centres. For publishing and scheduling across screens, see Digital signage & retail displays. Sound, conferencing and teaching workflows are developed under Meeting & conference rooms and Learning & presentation spaces.

Stage use needs a separate live-production and mounting brief. Studio use needs tests with the actual cameras, shutter settings, working light and content. These indoor reference walls do not establish suitability for outdoor, touring or camera-critical use.

For camera-critical LED, see TV studios. For stage sound, lighting and guest production, see Concert & event venues.

Workflow, boundaries and intended result

Composition

Twelve LED cabinets with their receiving electronics and power supplies, one combined scaler/sending controller, one content PC and one support laptop. Four data home runs feed the four columns; eight inter-cabinet links continue those chains. A mounting assembly, site installation infrastructure and a matched-spares plan complete the example.

Content path

The wall canvas is 1376 × 774. A standard HDMI source timing carries the prepared canvas, with agreed crop or scaling settings. Native canvas size and HDMI transport resolution are documented separately.

Boundaries

The base example uses one full-surface source. It does not include a multi-source compositor, CMS, ambient-light sensor, sound system or backup signal path. LED power demand remains subject to the selected cabinet specification. The proposed receiver arrangement must be confirmed with the cabinet supplier.

Intended result

Staff can start the agreed content, set the approved brightness and restore the documented configuration after maintenance.

Workflow, boundaries and intended result

Composition

Forty-eight LED cabinets with receiving electronics and power supplies, one combined scaler/sending controller, one content PC, one client source and one support laptop. Eight data home runs feed eight cabinet columns, with forty inter-cabinet links. Mounting, site infrastructure and a matched-spares plan follow the larger load and service area.

Content path

The content PC uses a 3840 × 2160 HDMI transport with an agreed crop for the 2752 × 1548 wall canvas. The second source uses a tested presentation timing and scales to the wall. The base workflow selects one source at a time.

Boundaries

This canvas exceeds a 3.9-million-pixel controller. The example requires a larger controller and a separate check of all eight loaded outputs. Spare outputs do not provide complete wall redundancy. Additional source windows, fibre links, camera synchronisation and a resilient signal chain are separately designed options.

Intended result

The approved content fills the larger surface with a documented pixel and port map, and staff can change between the two agreed sources.

Typical architecture · not a project drawing

Workflow, boundaries and intended result

Composition

Four identical FHD LCD panels, four service mounts, one compositor chassis with one capture card and one four-output graphics card, one layout-software licence set and one control workstation. Two HDMI input cables connect the client sources; four HDMI output cables connect the panels. Site infrastructure and one proposed matching spare panel are scheduled separately.

Content path

Each source is captured at the agreed 1920 × 1080/60 timing. Four independent 1920 × 1080/60 outputs form the 2 × 2 desktop. Layouts can show the two sources together or enlarge a selected source, with important text kept clear of the seams.

Boundaries

Four display outputs do not imply four captured sources or a particular IP-stream capacity. The chassis, cards, drivers and software licences must be specified as one compatible build. KVM, alarm workflows, IP decoding, remote access and failover are separate requirements. A spare panel is a service provision, not automatic recovery.

Intended result

Staff can recall the approved layouts, see both sources and identify a missing input or disconnected panel through the agreed checks and supported diagnostics.

Common mistakes

And how the design process prevents them.

  1. M01

    Mistake: Selecting a controller only from total pixels

    Prevention: Check every output and the actual receiver topology at the operating mode.

  2. M02

    Mistake: Calling any four-output device a multi-source compositor

    Prevention: Specify independent inputs, simultaneous windows, software and licences.

  3. M03

    Mistake: Publishing cabinet mass as the wall's total load

    Prevention: Add support, cabling and service loads through the structural design.

  4. M04

    Mistake: Guessing power from brightness or surface area

    Prevention: Obtain the power specification for the exact supplied cabinet.

  5. M05

    Mistake: Placing key text across LCD seams

    Prevention: Review the final window layouts and bezel compensation with real content.

  6. M06

    Mistake: Assuming a refresh-rate figure guarantees camera performance

    Prevention: Test the actual camera, shutter, working light and screen together.

12Inputs and FAQ

Before we begin.

What to send us, and practical answers before the project starts.

Should we choose LED or LCD?

We compare content, viewing positions, ambient light, available dimensions and maintenance needs. LED forms a continuous pixel surface from cabinets. LCD uses a fixed panel grid with visible seams. The processing and control workflow is selected separately for either technology.

Is the larger LED example a 4K wall?

VW-02 has a native raster of 2752 × 1548. It can be fed through an agreed 4K HDMI timing, but accepting that signal does not turn the physical surface into a 3840 × 2160 display.

How do you choose pixel pitch?

We review the nearest viewer, the farthest viewer and the actual content together. Pixel pitch helps determine visible pixel structure, while text size and layout determine whether information is readable. A sample viewed at the intended distance is more useful than a universal distance-to-pitch promise.

Can the wall show several sources at once?

VW-03 is designed for two captured sources in approved layouts. VW-01 uses one full-surface source; VW-02 selects between two. Additional simultaneous windows require a defined compositor or a verified processing mode with sufficient input and layer capacity.

How much power and support does it need?

The answer follows the selected cabinet or panel specification, total quantity, operating mode and support design. The two LED examples have calculated cabinet counts and masses, but their cabinet power data still needs supplier confirmation. The estimate identifies that gap instead of substituting a guessed wattage.

Will it look right on camera?

That requires a test with the intended cameras, shutters, frame rates, working light and content. An LED refresh-rate specification alone cannot establish freedom from bands or moiré. Camera-critical use is a studio or live-production design task.

What happens if a part fails?

The effect depends on the failed part and the specified signal and power paths. The base examples have single controllers and no automatic backup route. A project can add defined resilience and compatible spares, with tests for each agreed failure case.

What should we send to start?

Send the wall dimensions, viewing positions, example content and source list, together with photographs or drawings showing the structure and service space. Tell us the operating hours and whether source windows, filming or automatic recovery matter to the project.
