How to Hook Up HDMI Cable Television to a Projector


Bigger is better, as the saying goes, and projectors can provide serious home theater enthusiasts with a much larger viewing area than standard high-definition televisions. While slide shows and boring PowerPoint presentations may spring to mind when you think of video projectors, technology has moved forward over the years. Modern projectors offer full video support and include high-definition video and audio capabilities that can make them a cornerstone of any home theater. Streaming a high-definition cable television signal can be done with an HDMI connection between the cable box and the projector.

Things You'll Need

  • HDMI cable
  • HD-enabled cable box
  • HD-compatible projector with HDMI input port
  • Turn off your projector and cable box.

  • Slide one end of the HDMI cord into the "HDMI Out" port on the HD-enabled cable box.

  • Insert the second HDMI connector into the "HDMI In" slot on the projector.

  • Remove the projector's lens cap and plug in the device if necessary. Power on the projector, and wait for it to fully wake up.

  • Power on the cable box.

  • Set the projector to display the video from the HDMI connection. Some models change the input signal using a labeled button on the body of the projector, while others require you to change the input via the video options in the device's "Menu" settings. The cable television signal appears on the screen when the correct input setting is activated.

  • Adjust the zoom, focus and any other display settings on the projector as necessary. Follow the instructions that came with your projector.

Tips & Warnings

  • Disconnect wires connecting your cable box to any other monitor or television prior to hooking the device up to your projector.
  • Black images may appear overly dark on projectors using HDMI connections.
