How to Connect a LG Projector to a Cable Box


Properly connecting your set-top cable TV box to your projector is vital to ensuring a satisfying viewing experience. With your projector properly configured, you can broadcast cable TV channels onto a projection screen, dramatically expanding upon the normal viewing real estate provided by your television screen.

  • Place the projector on a sturdy horizontal surface, ensuring proper ventilation and a clear line of sight to your projection screen.

  • Connect the projector's power cord to an electrical outlet.

  • Connect the appropriate cable to the video output on your cable box. LG digital projectors are compatible with both RGB and HDMI video cables.

    If your cable box has an HDMI output, use the HDMI cable that comes with the LG projector, as this cable provides both high-definition video and audio output.

    If your cable box does not have an HDMI output, use the RGB-to-Component cable that comes with the projector. If you use this RGB cable, you will also need to connect an audio cable from the audio output on your cable box to the the "AUDIO IN" port on the back of the projector.

  • Connect the other end of the selected cable to the "HDMI" or "RGB" port on the back of the projector, depending on the type of cable used.

  • Verify that the cable box is turned on and then press the Power button on the projector.

  • Press the "Input" button on the projector's remote control. Press the left and right arrow keys to highlight either the "HDMI" or "Component" input and then press the "OK" button on the remote to select that input.
