I'm sure there was a better way to do this, but this Rube-Goldberg set up does the trick. Cable and cable box power run in the wall. Power from a lower outlet was brought up to the height of the TV. Cable box is velcrowed to the wall. The Chromecast (daughter's preference not mine) was just laid on the box temporarly until it could be plugged in. Everything disappears when the TV is mounted. And, it actually works. So, although I'm satisfied with the installation, I know there was an easier way to do this. I had looked into RF HDMI signals to eliminate the need to embed the cable and cable box wires into the wall. Anybody else do something similar? I would be interested to see the results.
