Say goodbye to running HDMI and RCA wires through walls, floors and/or attic space. New wireless devices can send High Definition 1080p video and sound to your wall mounted TV clear across the room. They conveniently eliminate those messy Audio and Video cables and awkward connections to your flat screen TV, making your HDTV look more like a work of art or a piece of home decor than a tangle of boxes and wires.
Connect your Blu-Ray DVD player and Cable box to the wireless transmitter box, on one side of the room and the wireless receiver box in the back of your wall mounted TV, on the other side of the room and presto, you got true HD picture and sound through Air express! The Video and Sound quality achieved is equal to an HDMI wired connection. The HD transmission even goes through walls, with virtually no latency to deal with (less than one millisecond).
Now you can place all your Audio Video components in a cabinet away from your wall mounted TV. No more stands under the TV no more wires on the floor.
With all that said you still need to have an electrical outlet on the wall behind your wall mounted TV ( wireless electrical transmission for TVs still needs some time to develop)
You can use these HD Wireless Devices for mounting your TV on concrete, brick or stone walls where hiding cables inside the wall is impossible or for TV fireplace installation and placing your cable box and Blu-Ray player away from the mantle.
