A:Answer I had Geek Squad come and install and mount my new TV and Soundbar in the beginning of September. They do give you the option to run the cords through the wall or to leave them hang (and later buy a casing cover to attach to your wall to hide the cords). If you do choose to run the cords through the wall (I did) they will make 2 holes. The first hole is up high behind the TV where the cords go into the wall and the second is down low behind your entertainment center where the cords need to come out to connect to your devices (satellite box, DVD/Blu Ray player, game system etc...). But they CANNOT run the power cords through the wall, only the HDMI/optical/coaxial etc. cords. They will tell you that if you want the power cords (I had 2, one for my TV and one for my Soundbar) ran through the wall too that you have to call a certified electrician to do that because of safety issues. So no matter what all cords cannot be ran through the wall by Best Buy Geek Squad. Hope this helps :)
