Royal Adelaide Hospital — board-grade conference room video wall

The brief

The Royal Adelaide Hospital’s executive conference room was running on an ageing dual-projector setup with a fabric screen. Image quality had degraded to the point where the room’s primary use — high-stakes board meetings, multi-disciplinary case reviews and visiting-clinician presentations — was being compromised by washed-out colour, dim ambient performance and constant lamp swaps.

The brief was unusually specific:

• A 4.5 m × 2.5 m image surface, edge-to-edge, no visible bezels.
• Daylight-readable: the room’s blackout blinds had been removed during a refurbishment and the wall sits opposite a 6 m glass façade.
• Whisper-quiet thermal performance — under 30 dB at the front face.
• Replace, commission and hand back the room within a 56-hour weekend window.

Why fine-pitch LED beat the alternatives

We modelled three options for the procurement team:

Option	Verdict
Laser projector + ALR screen	Cheapest CapEx but no ambient-light fix; lamp-equivalent service still required at year 5.
98” LCD video wall (4×3 grid)	Visible 1–2 mm seams between panels; colour drift between panels over 5 years.
P1.5 fine-pitch LED	Truly seamless; 600 nit native brightness handled the glare; 50,000 hr LED life beats both alternatives on TCO.

A 4.5 m × 2.5 m image at a 2.0 m primary viewing distance gives a 110° pixel angle of ≈ 0.04°, which P1.5 resolves cleanly under the 50× pixel-pitch rule of thumb. Anything coarser would have shown pixel structure to the front row.

What we shipped

• 210 × LUX P1.5 cabinets (500 × 500 mm), assembled into a 9 × 5 grid.
• Front-service mounting frame with magnetic module retention so any of the 1,050 modules can be hot-swapped from the front without touching the cabinet behind.
• Novastar VX1000 all-in-one controller with HDCP 2.2, accepting the room’s three primary inputs (resident PC, AirMedia wireless, AV-over-IP feed from theatre live-streams).
• Genelec near-field speakers flush-mounted in the wall surround so audio stays anchored to the image.
• Calibration to D65 white point @ 400 nit operating brightness, measured with a Klein K10-A colorimeter and re-checked at the 30-day handover.

The weekend

The install ran from 18:00 Friday to 02:00 Monday. Key decisions that protected the timeline:

1. Pre-built sub-assemblies in our Sydney workshop. Each 3 × 5 cabinet column was screwed to its sub-frame in the factory, calibrated to within ΔE < 1.5, and shipped in custom flight cases. On site we hung five columns instead of forty-five cabinets.
2. Dust-tight scaffolding plan. Our crew ran a poly-sheet partition with airlock zips so the corridor outside stayed clinical-grade clean throughout the rip-out.
3. Live commissioning before signoff. The hospital’s AV manager ran a full board-meeting rehearsal at 22:00 Sunday — three presenter swaps, dual-pane document sharing and a video-conference call with Sydney — before the wall was accepted.

Outcome (12 months on)

• Zero pixel failures across 1.05 M LEDs.
• Brightness drift measured at 1.4% (well inside the 5% threshold we warranty against).
• Two front-service interventions logged — both for cosmetic dust under the LED mask, repaired in under 15 minutes each without taking the wall offline.
• The hospital has since commissioned a second wall for the multi-disciplinary review room, using the same cabinet stock so spares are common.
