The Apple Cinema Display is a large widescreen LCD monitor with LED backlighting that is generally designed to connect directly to a Mac computer. If you own a Cinema Display, however, you may be thinking about using it as a TV, especially since its high-resolution screen has more pixels than a 1080p television. You can connect the display to any television box that has an HDMI port for output as long as you have the proper cables for the connection.
