How to Connect a Projector to an LCD TV

Updated February 21, 2017

Setting up a projector with an LCD TV requires a standard video cable and a TV set with output jacks to transfer the video signal from the television to the projector. The LCD TV's built-in speakers can be used for audio, or the TV can be connected to a home theatre receiver with attached stereo or surround sound speakers. The cable connection takes only a few seconds.

Check the back of the projector to determine the best connection to use. An S-video port is round, with four pin holes inside and three notches around the outer edge. RGB video jacks are red, green and blue, and will deliver a superior image over S-video. The LCD TV should be equipped with both types of connection jacks so choosing a cable depends on the projector.

Connect an S-video cable from the LCD TV to the port on the back of the projector. The plug inserts in one direction only, so take care to align the four pins in the plug with the four holes in the port.

Connect an RGB video cable by matching the red, green and blue plugs to the Video OUT ports on the TV and the Video IN ports on the projector.

Turn on the equipment and press the "Output" button on the TV remote control until the signal appears from the projector onto the screen.

Tip

Use the TV's built-in speakers or connect the set to an AV receiver for audio. The S-video and RGB connections supply picture only.

Warning

Unplug the components from the electricity while connecting video cables.

Things You'll Need

  • LCD TV with video output jack, either S-video or RGB component
