I’m currently building a new house. Walls are yet to be plastered, and no cabling or electrics have been put in (in fact it doesn’t have a roof yet, but will soon). I’m planning to wall mount my LG OLED C8 55” TV. It’s a medium to small size room, watching from Sofa. What are people’s thoughts on height? Also, and tips on the position of the hole/trunking for the cabling, and cable management in general? Thanks. Or should I not bother and sit on a media bench/stand?
