An MS face plate with HDMI refers to a wall plate designed for mounting, which includes a HDMI port for easy access to high-definition video and audio connections. These face plates are typically used in home theaters, conference rooms, or media setups, allowing users to connect devices like laptops, projectors, or TVs without the clutter of visible cables.
