Great idea for hiding the TV could work in any decor Fireplace or not! A sliding wall above the fireplace (a ventless model from Hearth Cabinet) conceals the television. Hide the TV in a variation on this theme?

I'm so not happy about having to put my television on the same wall as my photo gallery, but my new sofa is too big for the wall that it's on and so I have no other choices. This is the closest thing I have found that I like.
