If you connect VGA cables to both the Computer1 and Computer2 ports, make sure you label the cables. The teacher or other user needs to know which port is being used so that the correct source for full interactivity can be selected in the Easy Interactive Function menu screen. For full computer interactivity and dual pen support (using Easy Interactive Tools or other dual-pen application), you also need to connect a USB cable from the computer to the projector. Selecting the Source for Interactivity Selecting the source for Computer Interactive enables Easy Interactive Tools to be used on the "main computer" connected to the projector. Computers or other devices connected to other sources (and not selected) can use the built-in (embedded) interactive toolbar. 1. Press the Menu button, select the Extended menu, and press Enter. 2. Select the Easy Interactive Function setting and press Enter. 3. Select Use Source and press Enter. 4. Select the source where the computer is connected. For example, if you connected the computer to the projector's Computer1 port, select Computer 1. If you connected the computer to the projector's HDMI port, select HDMI. A computer connected to the selected source (and also connected to the projector with a USB cable) will work with Easy Interactive Tools and have dual-pen support. 2
