My TV was mounted onto the wall using a bulky bracket. From the left and right sides of the TV, the brackets would show. I covered them up by making two smaller sized boxes to fit and block the bracket area. I just recently remodeled my room, so I thought it would be nice to do something a little more creative than a standard shelf. The hidden shelf looks like a stack of dvds, but is in fact a hidden door.
