What It Takes to Be Both

Reference Standard

Digital Cinema Initiatives is the specification that governs how films are shown in commercial theaters. Meeting it is the hard part. Meeting it without giving up everything else is the rare part.

A display built to DCI is normally a theatrical instrument. It takes a feed from a cinema server, it shows the film, and that is the whole job. Ask it to switch to a games console, run four sources at once, or hold a photograph on the wall all afternoon, and it has no answer — because it was never asked to have one.

A Quantum wall is DCI-compliant and a complete HDMI home cinema in the same package. The theatrical standard governs how the picture is reproduced. Everything else on this page is what the same wall does the rest of the time.

The three cinema tiers

DCI defines picture in nits — a measure of light coming off the screen — and sets three levels for delivery.

The top tier is where projection runs out. Three hundred nits across the entire screen, not in a small highlight, is beyond what a lamp and a lens can hold — which is why cinema HDR in practice means a micro-LED wall.

And the colour to go with it

Light is half of the specification. The other half is DCI-P3 — the colour space films are graded in, and the one that decides whether a red is the red the colorist chose. Most large displays reach 90 to 95 per cent of it, which is close enough to look convincing until you put it beside the reference.

A Quantum wall covers full DCI-P3. Not most of the films' colour. All of it.

Proportion

Most large displays come in one shape. Some offer a wider one. A Quantum wall is built to the proportion the room calls for.

Sixteen by nine is a broadcast convention, not an architectural one. Film is wider. A gallery wall is wider still. And a stair hall, an entry, or a piece of vertical art wants a wall that is taller than it is wide — a shape almost nothing else is available in.

Because the wall is assembled from cabinets, the proportion is simply a choice: how many across, how many tall. Half-widths refine it further. Nothing is cropped to fit a fixed frame, and nothing is ordered from a list of presets.

Common configurations land where rooms tend to want them — a five-by-five reads as a familiar 16:9, a sixth column takes it past two to one, and a half-width column beyond that lands close to scope. There is no fixed catalogue and no upper limit; where a room calls for a single column or a single row, that is buildable too.

Pixel Pitch

Pixel pitch is the distance between one LED and the next. It sets how close a viewer can sit before the picture stops being a picture and starts being a grid.

The industry works to a rule of thumb: the pitch in millimetres is roughly the viewing distance in feet. A 0.9 millimetre wall wants nine feet. A 1.2 millimetre wall wants twelve.

That rule is not really about pixels. It is about everything else — the seams between panels, the shift in colour when you look from an angle, the small inconsistencies a wall reveals before its pixel structure ever does. Those are what push a viewer back.

Quantum calibrates every wall on site, panel by panel, and those artefacts are what the calibration removes. What is left is the pixel grid itself, and the grid lets you sit closer.

Read that again: a Quantum wall at 1.2 millimetres begins where the industry puts 0.9. And because a wall large enough to be worth building is usually watched from more than ten feet, the 1.2 is the right specification for most rooms — not a compromise, but the pitch the seating plan actually calls for. Specifying 0.9 for a twelve-foot seat buys resolution nobody is close enough to see.

Brightness & Heat

Brightness usually costs heat, and heat is what stops a display being built into anything.

A Quantum wall reaches 1,500 nits peak while drawing 90 watts per cabinet at maximum and about 45 watts in normal use — roughly 444 and 222 watts per square metre. Comparable walls of the same pitch draw between 495 and 766 watts per square metre at maximum, and reach between 600 and 780 nits doing it. Measured as light per watt, a Quantum wall is about three times as efficient.

The cabinet itself is the heat sink. Rather than concentrating heat at a few points and venting it, the structure spreads it across the whole back surface, and the LED panels shed their own heat forward. Evenly dispersed heat is cool heat, and cool heat is what lets the wall sit inside a tight pocket with an inch of clearance and no ventilation strategy.

What all that brightness is actually for

Every one of those DCI figures assumes a dark room. Forty-eight nits is a number that only makes sense with the lights off and the walls black — it was set for a commercial cinema, against projector technology. Consumer grades assume something a little more forgiving: a living room, dim or moderately lit. Neither assumes a wall of glass at two in the afternoon.

Ambient light does not dim a display. It raises the floor. Light falling on the surface lifts the blacks, and as the blacks come up the contrast the colorist built collapses — the picture goes flat long before it looks dark. The answer is to raise the whole image to meet the room, which takes headroom above the mastering reference.

That is what fifteen hundred nits is for. Not to make a three hundred nit master brighter for its own sake, but so the same wall can sit at reference in a blacked-out theater at night and lift to hold its contrast in a room full of daylight — and read correctly in both. A projector has no headroom to answer with, which is why the room has always had to be darkened around it.

Multi-Image

The wall is large enough to hold more than one thing at a time, so it does.

Multi-image processing starts at four simultaneous windows and expands from there. Each window can be any size and positioned anywhere on the wall — not dropped into a fixed quadrant. Windows are layered, so one can sit over another as a picture-in-picture overlay rather than beside it.

Layouts are pre-configured as presets and recalled from the control system, so a room can move from one arrangement to another as a single command.

One Complete System

Everything on this page arrives as one system, installed and calibrated by the people who built it.

The wall, the processing, the switching, the mounting hardware, the installation and the calibration are Quantum's. So is what happens afterward: a dedicated on-site machine gives Quantum secure remote access, so support never waits on a site visit.

Quantum works as part of the integrator's team. Control, sources and the rest of the system remain where they belong — with the dealer who designed the room.
