2, but i took 'TV' to strictly mean tv.
i also have 2 projectors, and a 'monitor'. but i think the answer suits, as those two tv's are the only devices i really watch television on. but my 'small' screens have certainly gotten more use lately than ever before. I never understood how people could watch movies on a laptop or tablet(i still don't like that) but i'm starting to find i do watch more youtube or streaming services on portable devices now. i'm starting to understand it makes more sense to have one small screen you can take anywhere, than to have a tv in every room(at my last house i installed a tv in the bathroom, for example). so, for now, i have a tv in the living room, tv in the bedroom, and projector in the basement theater(with that 'monitor' to help out in the equipment closet)
