LED wall or projector: which does your room actually need?
Neither is better. They are different answers to different rooms, and the room usually tells you which one it wants within ten minutes of honest questioning.

Start with the light you cannot control
Daylight is the projector’s enemy. A room with glazing, skylights or an operator who wants the blinds up is arguing for LED, which simply outshines the sun at close range. A room that can go dark - an auditorium, a cinema, a lecture theatre - lets a laser projector do what it does economically and quietly across a very large image.
Then the viewing distance
LED is bought by pixel pitch: the closer your nearest viewer, the finer - and dearer - the pitch must be. Projection scales to enormous sizes for a fraction of the panel cost, which is why Perth Modern School’s auditorium projects, and why Kelmscott’s performing arts centre runs a 7000 lumen laser projector with a pre-set cyclorama mode for scenery.
Then the content, and the life of the room
Fine text and spreadsheets want pixels. Atmosphere, scenery and architecture-scale colour want whatever the building can carry - at Stories at Yagan Square, that meant three kilometres of custom LED designed by our own team, because no standard product fitted the architecture. Consider service too: a projector fails at one point, predictably; LED fails a module at a time, visibly.
The honest answer
Bring the question to the room, not the brochure. That is what the design conversation is for.
