Planet Waves' HDMI Port Saver adapters solve depth, angle, and attachment issues when mounting a flat-panel TV to the wall. Simply connect the Port Saver to one of your TV's HDMI inputs before you install the TV, then you can plug your HDMI cable into the Port Saver's socket end after the TV is mounted. That way, you avoid sharply bending your HDMI cable, which can hurt performance. Maintains High Speed HDMI 1.4 spec for full support of 1080p video, 3D, 4k, Ethernet, and Audio Return Channel. All cables are CM & CL2 (UL) rated for in-wall installations. Limited lifetime warranty.
