Using the VGA cord/cable/wire with your projector
You connect the VGA to your tablet and to the wall jack. The audio cable is a separate cable and also need to be connected to your headphones jack on the tablet and the wall jack. If you need an audio cable, please let us know.
On your tablet you push Function and F7 to toggle the image onto the projector.
On the projector remote, you push the RGB button or “computer” or “input” button (may be labeled differently on different remotes) to toggle the input source to "PC 1" or "VGA 1" or "RGB 1" on the projector screen.
