Some netizens wrote privately:” When training, everyone needs to watch the projector. In fact, everyone has a computer. If the screen of the speaker’s computer is displayed on everyone’s computer desktop, the projector will not be needed in many cases. It will be convenient and will avoid seeing not clearly. Is there any way?

    The editor’s reply is as follows: “ We (AWIND) currently have a set of wireless presentation device that can wirelessly project the speaker’s computer on the projector, and allow 15 computer screens to receive at the same time. If there are more than 15 persons, it needs to build a dedicated multi-screen interactive server. It will support 100 computer receivers by the dedicated multi-screen interactive server.
