Barco XT 1.5 — cabinet grid & viewing distance, 4 × 2.25 m

Pixel pitch is the number that drives everything else in this preset. Barco XT 1.5 is a 1.5 mm pitch fine-pitch indoor cabinet, and that figure sets both the cabinet grid the calculator returns (7 × 7 cabinets for this wall) and the optimal viewing band for video content — approximately 1.5 m to 3 m, using the common 1.0×–2.0× pitch-to-metres guide. Sit much closer than 1.5 m and individual pixels start to resolve; sit well beyond 3 m and the fine pitch is no longer earning its premium over a coarser product.

At 1200 nits, Barco XT 1.5 is sized for a controlled indoor environment — a boardroom, lobby, control room or broadcast studio with managed ambient light, not a daylit atrium or storefront. The cabinet is wall-mount with front service, which keeps the install shallow and lets technicians access drivers and modules from the room side rather than needing rear egress. Native resolution at this wall size works out to 2800 × 1575, roughly 4.4 megapixels — enough headroom for full-HD source content mapped 1:1 with margin, or for cropped 4K content at reduced scale.

To use the calculator: drag the wall width and height sliders and watch the cabinet grid and native resolution recompute in real time. Barco XT 1.5 cabinets are a fixed physical size, so they snap to whole units — the actual wall the calculator reports (4.2 × 2.36 m for this preset) will differ slightly from whatever target size you enter, and that's expected rather than a rounding error.

What the calculator deliberately does not decide: the structural and rigging load the wall imposes on the host wall or truss, the power and data cable-run plan back to the rack, the video processor or scaler that feeds the cabinets, how source content resolution maps onto the 2800 × 1575 native canvas, and ambient-light calibration for the room the wall actually sits in. Each of those is a separate engineering step once the grid and resolution here are confirmed.
