The TV wall mount is thru 3 2x4 studs in the corner. It will not pull out ;-) Cable and power hookup is up there as well. This is the corner form my ham desk. In the corner is the 3" conduit, 2 wall pulls and the phone and network connections. Notice the heater in the foreground. One of those "Oil Filled" kind. Great little heater. Also notice the "Boo-Boos" under the air con. Yes, too much Great Stuff. Have to do some paint touchups. Will put trim around that and windows plus base boards.
