LG is one of several display manufacturers showing some type of wireless HD transmission system. The new LG71 Series includes 47- and 52-inch 1080p LCDs with built-in wireless capability. All of the video connections reside in a set-top box, seen here in the lower right corner of the photo. Connect your sources to the box, and it will transmit the signals wirelessly over a closed 802.11n network to the receiver embedded in the TV, reportedly from a distance of up to 65 feet. Not to show favorites, LG also offers this technology in their new PG70 plasma line.
