How to Change Wired Projectors to Wireless

Save

A home theater projector requires a video signal in order to display an image on a projection screen. To eliminate the video cable attached to the projector, use a HD wireless video transmitter. There are a number of these transmitters available from computer stores and electronics stores--all operating in a similar manner to transmit high-definition video from a video source to the projector. The setup time is minimal and requires a few video cables--these may be included with the HD wireless video transmitter but can be purchased at the same location as the transmitter if need be.

Things You'll Need

  • TV
  • 2 HDMI cables
  • Blu-ray player
  • Blu-ray movie disc
  • Turn the TV on that the Blu-ray player is attached to. Turn the Blu-ray player on with its included remote. Press "Menu." Select "Setup," "Video Setup," "Video Output." Select "HDMI" from the list of choices presented. Press the "Menu" button to exit the setup. Remove the HDMI cable that is attached to the TV from the Blu-ray player.

  • Place the wireless video transmitter next to the Blu-ray player. Plug the power cord from the wireless video transmitter into a wall socket for power. Plug one end of a HDMI cable into the HDMI input on the transmitter. Plug the other end into the HDMI output on the back of the Blu-ray player.

  • Eject the Blu-ray player's disc tray. Place a Blu-ray movie disc on the tray. Close the tray. Press the "Play" button to start the movie playing.

  • Press the "Input" button on the wireless video transmitter repeatedly until an LED lights up next to the "HDMI" text that is on the front panel.

  • Place the wireless video receiver next to the home theater projector. Plug the power cord from the wireless video receiver into a wall socket for power. Plug one end of a HDMI cable into the HDMI output on the receiver. Plug the other end into the HDMI input on the back of the home theater projector.

  • Press the "Input" button on the wireless video receiver repeatedly until an LED lights up next to the "HDMI" text that is on the front panel.

  • Turn on the home theater projector. Press the "Source" or "Input" button on the projector repeatedly until video appears on the projection screen.

Tips & Warnings

  • Audio will be transmitted as well as video to the home theater projector--this will enable any audio speakers that might be on the projector.
  • A standard-definition wireless video transmitter will be sufficient if you are only transmitting DVD-quality video.
