Most of the big names sell displays designed for commercial use (e.g. the screens you see at entrances to shopping centers), which are basically just big monitors, so no smart stuff, other than maybe being able to turn it on/off remotely. However instead of a $800 TV you are probably talking $5000 - not that the tech is much different, it's just that it's designed for commercial use. Is not seeing ads worth that much more for you?
