1. A display device comprising:
a communication interface configured to communicate with a first user terminal device;
a near field communication (NFC) interface having an NFC tag that stores information associated with the display device and connection information,
a display;
a memory configured to store at least one instruction; and
a processor configured to execute the at least one instruction to:
based on the first user terminal device being within communicative proximity of the NFC tag while the display device is in a powered-off state, establish a connection between the display device and the first user terminal device, and enter a standby mode in which a predetermined standby screen is displayed via the display;
receive information associated with content that is being output via the first user terminal device from the first user terminal device via the communication interface;
control the display device to output the content that is being output via the first user terminal device based on the information associated with the content; and
based on the first user terminal device being within communicative proximity of the NFC tag while the connection between the display device and the first user terminal device is established, terminate the connection and control the display to display a user interface (UI) indicating that the connection is terminated.
