Last night I mounted an extra TV we had in the office on my office wall. I hooked up an Apple TV and now with Apple Mavericks, I can extend my display wirelessly to that TV on the wall.
Here is a picture of my Apple Display, MacBook Display and now wireless LG TV display with my web sites on them.
The main purpose is to have meetings in my office, in addition to our conference room. So this gives us another meeting room with a TV. I can project my computer, iPad, iPhone or Android devices to it wirelessly.
