Neets Control’s - QueBec is a small control system for projectors which operates without any buttons. Instead it operates by VGA signal detection – retrofitting an existing installation can be done in no time, the company says.
When the system detects a VGA signal, for instance from a PC, it loops through to the projector and starts it up. Shutting down the PC similarly shuts down the projector automatically. In a retrofit situation it is straightforward to insert the device in the VGA signal chain between PC and projector.
