Sizing the projector to the room, not the catalogue
The order we work in: measure the room, fix the seating distance, derive the screen size, then choose the projector that can light that screen at the ambient-light level you actually watch in. Doing it the other way round — picking a projector then discovering the screen is too big for it — is the most common and most expensive mistake.
- Seating distance of 1.2 to 1.5 times the screen width suits most 4K home cinema rooms
- Larger screens need proportionally more light; area grows with the square of the diagonal
- Dark walls, dark ceiling and dark flooring add perceived contrast for free
- A matched screen is not optional in a bright room
