A:AnswerMax range is 150 from what the box says.. but at this range im sure it would need to be line of sight.. I live in a two story home and using the transmitter at about 75 feet apart choppy here and there but still manageable. I ended up moving the receiver and haven't had issues since. Only big downfall is not being able to change the channels if it is hooked up to a cable box.
A:AnswerThe audio will not line up perfectly, nor will it be 100% consistent. I know this because I had a perfect, unobstructed line of site between the transmitter and receiver and mine still had a noticeable audio lag at less than 12ft.
A:Answerit is line of site, preferably with out obstructions in the way (metallic). You should align the front of the units towards each other flat and similar height.
A:AnswerYes, it will work with any HDMI compatible device, but I would recommend the Nyrius wireless HDMI instead because this one alter the video quality by recompressing the video on the fly.
A:AnswerYes. The remote controls the Comcast box and Transmitter A connects to it. Transmitter A sends the signal to Transmitter B all the way across the room. Transmitter B connects directly to your TV. Works like a charm.
A:AnswerYes, that is exactly what this product does. You still need a short hdmi cable to connect your cable box to the transmitter and then another small hdmi box to connect the receiver to the TV, but you no longer need to run a cord in between the box and the tv.
