Display apparatus and method for controlling thereof

A method for controlling a display apparatus, the method comprising:

• obtaining a content image;
• sensing a connection of a first external display apparatus to the display apparatus through a first hinge device;
• obtaining a first content image corresponding to a portion of the content image and a second content image corresponding to a remaining portion of the content image, wherein the first content image is identified based on a resolution of the display apparatus;
• displaying the first content image through a display of the display apparatus;
• providing the second content image to the first external display apparatus to control the second content image to be displayed on the first external display apparatus;
• sensing rotation of the first external display apparatus relative to the display apparatus while displaying the first content image;
• and
• adjusting a size of the second content image provided to the first external display apparatus based on an angle at which the first external display apparatus is moved while maintaining a size of the first content image.

A non-transitory computer-readable medium storing computer instructions for a display apparatus to perform an operation when executed by a processor of the display apparatus, the operation comprising:

• obtaining a content image;
• sensing a connection of a first external display apparatus to the display apparatus through a first hinge device;
• obtaining a first content image corresponding to a portion of the content image and a second content image corresponding to a remaining portion of the content image, wherein the first content image is identified based on a resolution of the display apparatus;
• displaying the first content image through a display of the display apparatus;
• providing the second content image to the first external display apparatus to control the second content image to be displayed on the first external display apparatus;
• sensing rotation of the first external display apparatus relative to the display apparatus while displaying the first content image;
• and
• adjusting a size of the second content image provided to the first external display apparatus based on an angle at which the first external display apparatus is moved while maintaining a size of the first content image.

A display controller comprising:

• an interface configured to connect with a display apparatus and a first external display apparatus;
• at least one processor configured to:
• obtain a content image,
• obtain, based on the display apparatus being connected to the first external display apparatus through a first hinge device, a first content image corresponding to a portion of the content image and a second content image corresponding to a remaining portion of the content image,
• wherein the first content image is identified based on a resolution of the display apparatus,
• provide the first content image to the display apparatus,
• provide the second content image to the first external display apparatus, and
• adjust, based on an angle between the display apparatus and the first external display apparatus changing while displaying the first content image, a size of the second content image provided to the first external display apparatus according to the angle while maintaining a size of the first content image.
