a communication unit configured to perform a connection with the other display device; and a control unit configured to control the pointer to be displayed on at least one of the display device and the other display device based on a placement state of the display device and the other display device and movement information received from the remote control device. ## Claims ### Claim 1 A display device, comprising: a primary display; a communication unit configured to communicate with an other display device wherein a side of the other display device is located proximate to a side of the display device; and a controller configured to: cause a pointer corresponding to a remote control device to be displayed on the primary display or a secondary display of the other display device, wherein a position of the displayed pointer is based on a movement of the remote control device relative to the display device and a placement state of the display device relative to the other display device; and cause the display device or the other display device to execute a control command in response to a control command input received via the remote control device, wherein the control command is executed by the display device or the other display device based on an operation mode of the display device, wherein: a first content is displayed on the primary display; a second content is displayed on the secondary display; and the controller is further configured to cause at least one reference line to be displayed on the secondary display indicating an available aspect ratio for setting a new aspect ratio of the first content in response to a drag input of the pointer from the primary display to the secondary display. ### Claim 2 (depends on 1) The display device of claim 1, wherein the controller is further configured to set respective device position coordinates corresponding to the display device and the other display device based on the placement state of the display device and the other display device. ### Claim 3 (depends on 2) The display device of claim 2, wherein the controller is further configured to set a pointer coordinate system of the primary display based on the set device position coordinates. ### Claim 4 (depends on 1) The display device of claim 1, wherein the controller is further configured to: determine coordinates corresponding to a position of the displayed pointer based on the placement state and the movement of the remote control device; and cause the communication unit to transmit the determined coordinates to the other display device. ### Claim 5 (depends on 4) The display device of claim 4, wherein the controller is further configured to display at least a portion of the pointer on the primary display when a display position of the at least a portion of the pointer corresponds to the primary display based on a size and the determined coordinates of the pointer. ### Claim 6 (depends on 1) The display device of claim 1, wherein when the operation mode of the display device is set to a twin mode, the control command is executed by the display device or the other display device based on which device is controlling the twin mode, the twin mode corresponding to a single content being displayed across the primary display and the secondary display. ### Claim 7 (depends on 1) The display device of claim 1, wherein when the operation mode of the display device is set to a split mode, the control command is executed by the display device or the other display device based on whether the pointer is displayed on the primary display or the secondary display when the control command is input, the split mode corresponding to different content being displayed on the primary display and the secondary display. ### Claim 8 (depends on 1) The display device of claim 1, wherein: the controller is further configured to cause the first content to be displayed across the primary display and a portion of the secondary display in response to a movement of the pointer from the primary display to the secondary display. ### Claim 9 A method of operating a display device, the method comprising: displaying a pointer corresponding to a remote control device on a primary display of the display device or a secondary display of another display device, wherein a side of the display device is proximate to a side of the other display device; changing a display position of the pointer based on a movement of the remote control device relative to the display device and a placement state of the display device relative to the other display device; and executing a control command via the display device or the other display device in response to a control command input via the remote control device, wherein the control command is executed by the display device or the other display device based on an operation mode of the display device, wherein: a first content is displayed on the primary display; a second content is displayed on the secondary display; and the method further comprises displaying at least one reference line on the secondary display indicating an available aspect ratio for setting a new aspect ratio of the first content in response to a drag input of the pointer from the primary display to the secondary display. ### Claim 10 (depends on 9) The method of claim 9, further comprising setting respective device position coordinates corresponding to the display device and the other display device based on the placement state of the display device and the other display device. ### Claim 11 (depends on 10) The method of claim 10, further comprising setting a pointer coordinate system of the primary display based on the set device position coordinates. ### Claim 12 (depends on 9) The method of claim 9, further comprising: determining coordinates corresponding to a position of the displayed pointer based on the placement state and the movement of the remote control device; and transmitting the determined coordinates to the other display device. ### Claim 13 (depends on 12) The method of claim 12, further comprising displaying at least a portion of the pointer on the primary display when a display position of the at least a portion of the pointer corresponds to the primary display based on a size and the determined coordinates of the pointer. ### Claim 14 (depends on 9) The method of claim 9, wherein when the operation mode of the display device is set to a twin mode, the control command is executed by the display device or the other display device based on which device is controlling the twin mode, the twin mode corresponding to a single content being displayed across the primary display and the secondary display. ### Claim 15 (depends on 9) The method of claim 9, wherein when the operation mode of the display device is set to a split mode, the control command is executed by the display device or the other display device based on whether the pointer is displayed on the primary display or the secondary display when the control command is input, the split mode corresponding to different content being displayed on the primary display and the secondary display. ### Claim 16 (depends on 9) The method of claim 9, wherein: the method further comprises displaying the first content to be displayed across the primary display and a portion of the secondary display in response to a movement of the pointer from the primary display to the secondary display.
