The screen at the front of a room is the one screen in a building that regularly stops a meeting.
Presentation in meeting rooms generally depends on a physical connection: a cable, an adapter that fits the laptop in the room, or guest network access arranged in advance. Each is a failure point at the start of a meeting, and the room screen is where meetings most often stall.
Ava Display issues a time-limited code, rendered on the screen as digits and a QR. The presenter scans it and casts from their seat. No client software, no cable, no guest network provisioning. The host sets the validity window and the target, which may be a single screen or every screen in the room.
Joins are restricted to networks the organisation has declared, enforced at the door rather than assumed: a device on any other network is refused. Each join is recorded against the device that took the screen, so room usage is attributable.
Digits and QR rendered on the screen. Presenter scans and casts from their seat.
Single use, with a validity window set by the host. Consumed codes are void.
Target selected at issue: one screen or every screen in the room.
Restricted to declared networks. No declared network, no joins.
Every join attributable to the joining device.
The target is selected when the code is issued. In a room with multiple screens, one code places the presenter on all of them.
