HDMI DISPLAY-SIDE WALLPLATE SIGNAL BOOSTER With Tripp Lite's HDMI Display-side Wallplate with Signal Booster, you can now hide that HDMI cable that's connected to the flat screen HDTV hanging on the wall, by running the cable behind the wall and into the back of the faceplate. The built-in signal booster allows the video source (DVR, SAT box, etc.) to be located beyond the 5 meter HDMI length restriction. The signal is fully regenerated to run the last few feet to the display.
