Abstract: The present disclosure relates to a display device, a user terminal device, a method for controlling a display device, and a method for controlling a user terminal device. The disclosure relates to a method in which a display device outputs content that is being output via a user terminal device based on a content request event associated with a request for the display device to output information associated with content that is being output via the user terminal device.

Abstract: A display device and a method capable of rotating a display based on a type of a user command are provided. The display device according to the disclosure receives a user command while first content is displayed on the display, the display being configured to operate in a first orientation while displaying the first content, maintains the display to operate in the first orientation when the received user command is a command to control a feature corresponding to the first content, determines, based on a type of a second content, to control the display to operate in the first orientation or a second orientation different from the first orientation when the received user command is a command to display the second content on the display, and controls the motor to rotate the display based on the determined first orientation or the second orientation.
