Hotel TVs, same panels as consumer models with different supporting hardware and stock calibrations. These are actually dimmer than the consumer models to increase panel longevity.

They tend to lack gaming features like high/variable refresh rate but they're more functional as normal TVs than digital signage displays.

They have similar OSes as the consumer models and can run the same apps but don't have ads unless the operator wants them to and can be centrally managed, support internal IPTV networks, etc.
