Instructions

  1. 1

    Turn off your stero and TV.

  2. 2

    Plug one end of the video cable into your laptop computer. If you have both a newer laptop that is equipped with an HDMI port along with a high-definition television, use the HDMI cable. However, a more typical situation involves using a VGA to composite cable. If your laptop doesn't have an HDMI port, plug the VGA end of the VGA to composite cable into your laptop's VGA port.

  3. 3

    Connect the opposite end of the video cable into your TV. Video input ports can be found on the front, sides, or back of the TV. Look for the name of the input port next to the video jack you've plugged your computer into. For example, many TVs label the input jacks "Input 1," "Input 2" and "Input 3." Remember the name of the jack you've plugged your computer into.

  4. 4

    Connect your laptop to your stereo receiver using the 3.5mm to RCA cable. Plug the 3.5mm end of the cable into your laptop's headphone jack. Plug the opposite end of the cable, which includes a red and white jack, into the audio input jacks of your stereo receiver. Look for the name of the input source next to the audio jacks you've plugged you computer into. For example, many stereo receivers have input jacks labelled "Television," "DVD," "VCR" and "AUX." Remember the name of the jack you've plugged your computer into.

  5. 5

    Turn on your TV. Change the input source so that it displays your computer by pressing the "Input" or "Source" button on your television's remote control. Press the button on the remote until your TV displays the input source you've noted in Step 3. For example, if you've plugged your computer into "Input 3," use your remote to change the TV's input to "Input 3."

  6. 6

    Turn on your stereo and change the input audio source to the input jack that your computer is plugged into. Use your stereo's remote control or press the "Source" button on the stereo receiver. Press the name of the audio input source you've noted in Step 4. For example, if you've plugged your computer into the "AUX" input jack, press the "AUX" button on the controller or stereo receiver.

  7. 7

    Make sure your laptop is displaying video to the TV. Open "Display Settings" on your computer by clicking "Start," "Control Panel," "Appearance and Personalization," "Personalization" and "Display Settings." Under "New Display Detected," select "Mirrored" display and click "OK." Your computer should now mirror display identical content on your laptop screen and your TV screen.

  8. 8

    Turn up the volume on your laptop to make sure audio is being sent to the stereo.
