When there are two or more people meeting, the screen of the computer or mobile phone or tablet will be too small.We need to be able to transfer the contents of the computer or mobile phone and tablet to the big screen simply and quickly.The current large-screen display solution is connected to the big screen through the HDMI or VGA interface of the computer or mobile phone. This solution requires all the devices to have the same interface, and limited by cable type. In order to solve this problem, AVWIN provide the wireless airplay system with mature technology, high stability and wide application.The participants can project the video, images and files of the computer or mobile phone and tablet to the large screen display through wireless projection in any place of the meeting room.
