Facts worth citing

The short answers to the questions we are asked most. Each is stated with its method so it can be checked rather than taken on trust.

How do I choose a pixel pitch?

Pixels stop being individually resolvable at roughly 3.438 times the pitch in millimetres, derived from one-arcminute visual acuity — the standard 20/20 limit. A P2.5 panel is pixel-perfect from about 8.6 metres. Specifying to that limit typically doubles panel cost for sharpness nobody in the room can perceive, so the commercial choice normally sits between the retina limit and the legibility floor.

How bright does a shop window screen need to be?

Roughly 5,000 to 8,000 nits facing out through glass, against 800 to 1,500 nits for the same screen indoors. It is competing with daylight and with reflections off the glass. Under-specifying brightness cannot be corrected afterwards without replacing the panels, which makes it the most expensive mistake in retail LED.

What size will the wall actually be?

LED walls build from fixed cabinets, most commonly 500mm, so the buildable size steps in cabinet increments. A requested 3.7m width is built as 3.5m or 4.0m. Always ask a supplier for the buildable size rather than the requested one.

What does an LED display cost to run?

Multiply area in square metres by average draw — around 200 W/m² indoors and 320 W/m² for a shop window — then by hours and by your unit rate. Panel datasheets quote maximum power, which assumes an all-white screen at full brightness; no real content sustains that, so datasheet figures overstate running cost roughly threefold.

What does an LED video wall cost to buy?

It depends several-fold on pixel pitch, so a single figure would mislead. We publish what named suppliers state on their own public pages, in the UK, Ireland and the United States, at prestige-digital.net/pricing — including the four items most often missing from a quote.

Glossary

Pixel pitch

The distance in millimetres between the centres of two adjacent LEDs. A P2.5 panel has 2.5mm between pixels. Smaller pitch means more pixels per square metre, a sharper image at close range, and a higher price — halving the pitch roughly quadruples the pixel count.

Nits (cd/m²)

A measure of screen brightness. Indoor commercial displays typically run 800–1,500 nits; a screen facing out through glass into daylight needs roughly 5,000–8,000 nits to stay readable.

Cabinet

The modular unit an LED wall is built from, most commonly 500mm × 500mm. Walls step in cabinet increments, so a 3.7m width is built as 3.5m or 4.0m, never 3.7m.

IP rating

Ingress protection. IP65 front is the normal requirement for an outdoor screen; IP31 is typical indoors. The first digit covers dust, the second water.

Fine pitch

Loosely, any pitch below about 2mm. Used where people stand close — reception walls, control rooms, retail features. Substantially more expensive per square metre.

Transparent LED

Panels with high light transmission so a shop window still reads as a window. The trade-off is inherent: more transparency means less physical LED area, so transparent panels are dimmer than solid panels of the same pitch.

Sending and receiving cards

The controller hardware that drives an LED wall. A sending card takes the video signal; receiving cards inside the cabinets drive the panels. Sized to the wall's resolution, so this is a fixed cost rather than a per-square-metre one.

Bank end

In a casino, the display surface at the end of a row of gaming machines. Visible from across the floor, which makes it the highest-leverage signage position in the room.
