Did the presenter leave the conference room without
cutting off the network connection?
In Network Presentation, the connection with the computer that was previously connected can be cut off
when another computer tries to connect with the projector, and it connects with the computer that is trying to
connect.
Therefore, when a projector keyword is not set for the projector, or if you know the projector keyword, you
can cut off the current connection and, if you perform a connection operation, you can connect to the
projector.
When a projector keyword is set for the projector, if you do not know the projector keyword, cut off
projection from the projector and reconnect. To cut off connection from the projector, press the [Esc] button
on the remote control, select "Close" from the close menu and press the [Enter] button on the remote control
When it cuts off, you can connect from the target computer.
