  1. 1

    Position the LED projector in front of the screen or other surface where you will be displaying the image.

  2. 2

    Insert the HDMI cable into your computer or other video source and plug the opposite end into the "HDMI IN" port on the LED projector. If your computer does not have an HDMI port, use a DVI or VGA cable to connect the devices.

  3. 3

    Plug in your LED projector to the nearest wall outlet. Press the "Source" button on the projector until the image from your source appears on the surface.

  4. 4

    Move the projector closer to the screen for a smaller, more focused image. Move the projector farther away from the surface for a larger image. If your projector features a focus ring, slowly turn the ring clockwise to shrink the image or turn it to the left to make the image larger.
