The conference room setup a hotel is judged on — a projector or a large panel, a screen and a room-name board, sound that carries, an interactive whiteboard and the table everyone sits at.
Something to show on, something to hear through, and a table. After that it is the room: a projector suits a hall, a large panel suits a boardroom, and an interactive whiteboard earns its place where people work rather than watch.
Room size and daylight decide it. A projector covers a big room cheaply but wants the blinds down; a panel stays readable with the curtains open and has no lamp to replace. Tell us the room and we'll size it.
Yes, and that is the usual job. Send the room list with dimensions and we'll spec them to match, so the same inputs and the same remote work in every one.
