Transmitter is behind a glass door of a media center in the living room and is separated from the receiver in the bedroom by 1 double sheet rock wall and/or a solid wood door (likely not as challenging an environment as some reviewers).Transmitter gets its signal from one output of an HDMI splitter that splits the output from our X1 Xfinity cable box, with the other going to a Yamaha sound-bar

The only issues I've had are:- sometimes it will lose the sound output

I split the HDMI output of the cable box and used this device to transmit the signal to the remote TV.

Thank u very much.
