Firstly I must say this is the best TV we have had to install in a playroom. The TV is a Samsung 8000 series 3D and the specification for the job was to have the TV out of reach of the children and to hide the cables in a conduit to stop them having access to the cables.
We used a tilting bracket so that the TV could tilt forward slightly so that the kids were able to watch it comfortably. The TV itself was mounted higher than your average install as to keep the TV out of harms way for the children. The cables were put into a d-line conduit so as to again keep out of harms way for the children whilst not spoiling the décor of the room.
