I have decided to put my television on the wall it is a new build that has dry lined walls. It is a fairly short run as I do not want it to high. I was just going to dig a channel out and hide the wires then fill it back in with filler. I might install a mains socket that is just ran from a plug on a cable block under my tv unit. I am just wondering is there any reason for putting this in trunking? I understand that the metal kind is good to prevent drilling into wires but I am well aware that they will be there. Thanks for any help.
