I am starting a project and am looking for advice on what I'll need. I want 3 tvs mounted on one wall. I will have surround sound but only care about volume for one tv at a time. I'd like to be able to control 3 boxes and the sound thru one remote. I have uverse as a provider currently.The boxes will be behind a wall so I'm assuming I will need IR.Any tips on what I need or consider? Is this doable with uverse as my provider? Any advice is much appreciated.
