Picture perfect for any room, this 22" diagonal HDTV delivers crisp, clear visuals thanks to 720p resolution, a digital comb filter, and image-noise reduction technology. Built-in speakers provide equally impressive sound. Connecting another digital device like a cable box or Blu-ray player is simple thanks to an integrated HDMI port. From Coby. With a TV that has a built-in high-definition tuner, HDTV may be received from broadcasting companies that transmit high-definition signals, or may require a subscription to a digital cable or satellite service to receive HDTV programming, where available. Contact your local cable or satellite provider for details and costs if you are interested in high-definition TV from your service provider.
