Ever since the arrival of Samsung's The Frame TVs, the idea of 'art TVs' has become more and more popular. These are TVs that look like a picture frame, and instead of showing nothing when you're not watching them, they can show beautiful artworks. In many cases (and particularly with the Samsung Art Store), that means famous paintings and photographs from truly great artists.
You now have options from Hisense and TCL as well as Samsung, while Amazon Fire TVs from all kinds of makers (including Amazon, obviously) have an 'Ambient Mode' that can work similarly.
