Start with the system, not the specification.
The best projection results start before the projector is ordered. Screen width, projector position, ceiling height, ventilation, room reflectivity, cable routes and service access should be coordinated early.
This is especially important with Barco, Epson QL and cinema-class platforms where lens choice can unlock far more architectural freedom.
What to establish in a real project
Begin with the room dimensions, screen image width, screen gain, seating distance, projector position and whether the room will be fully light controlled. From there, calculate the required throw ratio and target luminance before choosing a projector family.
Why this matters at the high end
Premium projection systems can deliver extraordinary images, but they are less forgiving of design mistakes because the screen is larger and the performance target is higher. Optics, room surfaces, HDR processing and calibration all interact.
For a new cinema, send us the room plan before the projector position is fixed. That gives the optical system the greatest chance of being designed correctly.
The projector position is an architectural decision
Ceiling height, sight lines, screen wall depth, throw distance, cable routes, cooling and future service access all affect where the projector can live. These decisions are difficult and expensive to correct after the room is finished.
For interchangeable-lens platforms, early geometry can unlock far more elegant installation positions. Treat projector and lens selection as part of architectural coordination, not a late-stage equipment choice.
