able to hook you up with the right equipment. I just did this in the sitting room of a client's bedroom. We put the TV over their fireplace and the components are housed in a linen closet in an adjacent bathroom. Below are the initial design drawing and the room prior to furnishing it. Hope this helps
picture hooks to mount the plates. When I'm not so lucky to be working with plates designed for hanging I use The-Original-Invisible-Disc-Adhesive-Plate-Hangers. They are completely invisible, and are secured to the back of the plate using an adhesive. Super simple, good luck!
