LED video walls have replaced projectors as the go-to display technology for enterprise boardrooms, experience centres, and large meeting spaces. But the specs can be confusing — pixel pitch, nit brightness, processing, content management — and vendors don't always explain what matters for your specific use case.

This guide is based on our experience installing LED walls for Amadeus Software Labs (16-ft boardroom wall), GE Vernova (223-inch curved experience centre), Oracle (dual 130-inch café displays), and dozens of other enterprise clients.

When Does an LED Wall Make Sense?

Choose LED when:

The display needs to be larger than 100 inches

The room has ambient light (LED walls are much brighter than projectors)

You need seamless, bezel-free visuals (no visible panel gaps like tiled LCDs)

The installation will be permanent or semi-permanent

Stick with displays or projectors when:

The space is small (under 20 seats) — a 75" or 85" display is more cost-effective

Budget is under 10L for the display alone

The content is primarily data/spreadsheets (text readability at close range favours displays)

Pixel Pitch: The Most Misunderstood Spec

Pixel pitch (measured in mm) is the distance between LED pixels. Smaller = sharper. But smaller also = exponentially more expensive.

The right pixel pitch depends on viewing distance, not room prestige:

| Viewing Distance | Recommended Pixel Pitch | Typical Use Case | |---|---|---| | 1.5–3 metres | 0.9–1.2mm | Boardroom, close-up viewing | | 3–6 metres | 1.2–1.5mm | Townhall, training room | | 6+ metres | 1.5–2.5mm | Cafeteria, lobby, experience centre |

At Amadeus, we used Absen 1.2mm for the 16-ft boardroom wall because executives sit 2–4 metres away. For the cafeteria's dual 10-ft walls, we used 1.5mm because the nearest viewer is 5+ metres away. Using 1.2mm in the cafeteria would have doubled the cost with no visible quality improvement.

Brightness and Processing

LED walls are rated in nits. For indoor corporate use:

300–600 nits for light-controlled rooms (boardrooms with dimmable lights)

600–1000 nits for rooms with some ambient light (training rooms, cafeterias)

1000+ nits for high-ambient environments (lobbies, experience centres with glass walls)

Processing matters more than most buyers realize. The video wall processor handles scaling, colour calibration, and input switching. We use Novastar and Brompton processors depending on the application. Cheap LED panels with a poor processor look worse than expensive panels.

Content Management

An LED wall is only as good as what's on it. For experience centres, we implement centralized CMS (Content Management System) with show control — pre-programmed sequences that staff can trigger for client presentations without needing AV expertise.

At GE Vernova's experience centre, the 223-inch curved display runs a custom show control system that transitions between product demos, data visualizations, and video conferencing with one-touch presets.

Integration with Video Conferencing

A common mistake: installing a beautiful LED wall that can't be used for Teams or Zoom calls. The wall processor needs to accept standard video conferencing outputs (typically HDMI from a codec), and the cameras need to be positioned to avoid capturing the LED wall's moiré pattern on camera.

At Amadeus, the boardroom's 16-ft wall seamlessly switches between presentation mode (full LED canvas) and video conferencing mode (remote participants on wall, camera capturing in-room attendees) via the QSC Q-SYS control system.

Budget Guidance

Rough ranges for indoor corporate LED walls (panels + processor + installation, excluding content):

| Size | Pixel Pitch | Budget Range | |---|---|---| | 100–130" | 1.5mm | 15–25L | | 130–170" | 1.2mm | 25–45L | | 170–220" | 1.2mm | 45–80L | | 220"+ curved | 1.2mm | 80L+ |

These are indicative. Actual costs vary significantly by brand, mounting requirements, and processing needs.

Our Recommendation

Start with the use case, not the spec sheet: 1. Who will be in the room, and how far from the wall? This determines pixel pitch. 2. What content will it display? Presentations need sharp text. Video needs smooth motion. 3. Will it be used for video conferencing? This determines processing and control integration. 4. Who will operate it day-to-day? Complex systems need simple interfaces or they won't be used.
