2 . The display apparatus of claim 1 , wherein the at least one processor is further configured to execute the instructions to:

based on receiving an image signal from the source apparatus, control the communication interface to transmit the image signal to the external display apparatus, and

display a screen corresponding to the image signal by using the display apparatus and the external display apparatus.

3 . The display apparatus of claim 1 , wherein the sensor comprises a plurality of sensors, and

wherein the at least one processor is further configured to execute the instructions to:

based on detecting connection of the external display apparatus at a first sensor among the plurality of sensors, identify an arrangement form based on the first sensor; and

generate the integrated apparatus information according to the arrangement form based on second resolution information of the external display apparatus in the second apparatus information, and first resolution information of the display apparatus in the first apparatus information.

4 . The display apparatus of claim 3 , wherein the at least one processor is further configured to execute the instructions to:

based on receiving an image signal from the source apparatus, control the communication interface to transmit a signal controlling the external display apparatus to display a part of a screen corresponding to the image signal based on the arrangement form, to the external display apparatus.

5 . The display apparatus of claim 3 , wherein the at least one processor is further configured to execute the instructions to:

change a resolution of a screen corresponding to an image signal based on the resolution information in the integrated apparatus information; and

control the communication interface to transmit a signal controlling the external display apparatus to display a part of the screen with changed resolution based on the arrangement form, to the external display apparatus.

6 . The display apparatus of claim 5 , wherein the image signal was received from the source apparatus, or obtained by the display apparatus.

7 . The display apparatus of claim 1 , wherein the at least one processor is further configured to execute the instructions to:

based on detecting connection of the display apparatus according to turn-on of the external display apparatus, receive the second apparatus information from the external display apparatus, and generate the integrated apparatus information based on the first apparatus information and the second apparatus information.

8 . The display apparatus of claim 1 , wherein the at least one processor is further configured to execute the instructions to:

based on detecting disconnection of the display apparatus according to turn-off of the external display apparatus, update the integrated apparatus information based on the first apparatus information, and

wherein the updated integrated apparatus information excludes second resolution information of the external display apparatus in the second apparatus information.

9 . The display apparatus of claim 1 , wherein the at least one processor is further configured to execute the instructions to:

based on receiving a control signal from the source apparatus or a remote control apparatus, transmit the control signal to the external display apparatus.

10 . A control method of a display apparatus, the control method comprising:

based on detecting connection with an external display apparatus,

receiving second apparatus information corresponding to the external display apparatus from the external display apparatus;

generating integrated apparatus information based on the second apparatus information and first apparatus information corresponding to the display apparatus;

transmitting the integrated apparatus information to a source apparatus;

based on detecting disconnection of the external display apparatus through the sensor,

updating the integrated apparatus information by excluding the second apparatus information; and

transmitting the updated integrated apparatus information to the source apparatus, wherein the integrated apparatus information comprises:

resolution information on resolutions that can be displayed through the display apparatus and the external display apparatus, and

wherein the updated integrated apparatus information comprises:

14 . The control method of claim 12 , further comprising:

changing a resolution of a screen corresponding to an image signal based on the resolution information in the integrated apparatus information; and

transmitting a signal controlling the external display apparatus to display a part of the screen with changed resolution based on the arrangement form, to the external display apparatus.

15 . The control method of claim 14 , wherein the image signal was received from the source apparatus, or obtained by the display apparatus.

16 . The control method of claim 10 , further comprising:

based on detecting connection of the display apparatus according to turn-on of the external display apparatus, receiving the second apparatus information from the external display apparatus, and generating the integrated apparatus information based on the first apparatus information and the second apparatus information.
