The wireless projection function is only available for the model which is equipped with integrated Acer Wireless Presentation Gateway (WPG) module. Acer WPG enables multiple users to connect to an Acer projector wirelessly. This eliminates the need to plug and unplug cables, enabling more efficient use of meeting time, especially when there is more than one presenter in a meeting. To perform wireless projection, you have to change the input source type to "Wireless"...

    Wireless projection Connecting to a projector Once you’ve installed the software, you will be able to connect to any projector that is equipped with the Acer WPG. To connect to a projector, simply double- click the Acer WPG icon on your desktop to launch the application. The application will automatically detect available WPGs. Each WPG is iden- tifiable by the "AcerProjector" indicator in the SSID. If the projector is installed in a permanent location, you may also choose to assign a specific SSID to that projector, indicating, for example, the number of the room in which the projec- tor is installed (refer to "Configuration" later in this guide). If there are multiple WPGs within the range of your notebook's receiver (they may be in different rooms), and the feature is enabled (refer to "Configuration" later in this guide), you will be able to identify the correct one by the "Projector ID" indicated in the top left-hand corner of the projected screen. The Projector ID consists of four randomly-generated numbers. Entering these numbers into the WPG application on your notebook will restrict your connection to only that projector. Only one user can use the WPG at any time; if another user wishes to use the projector, you will need to click Disconnect to stop using the projector, and al- low someone else to use the projector..English...
