Hi, i am looking to have a wall-mounted TV in the center of my wall, and have the HDMI, Power, VGA cable run from the loft to this upstairs spare room, (this wall is between us and the neighbours) can anyone suggest the best way to go about this?
I am thinking either channel out a whole line from center of the wall up to the ceiling so cut out the plaster say 1inch thick, run the wires, and then fill the channel with Filla and then wall paper.
or cutting a hole say 2inch diameter, and poking something in and hoping that it arrives somewhere in the loft and thus pulling through all wires.

help!
