Commercial TVs used in airports and museums often have device bays that can interact with at least power and HDMI, sometimes much more. The problem is they are quite expensive. Partly due to fewer being sold, but also engineering the modular bus, fancy connectors, etc. Some of the plug-in boards are as expensive as a whole consumer TV.
