generating second angle information representing an installation angle of a second display apparatus based on a detection value of a sensor provided in the second display apparatus; and reporting information representing a difference between the installation angle of the first display apparatus represented by the first angle information and the installation angle of the second display apparatus represented by the second angle information by the second display apparatus. ### Claim 2 (depends on 1) The display method according to claim 1, wherein the reporting is displaying a first guide image, by the second display apparatus, for guiding adjustment of the installation angle of the second display apparatus, and the first guide image shows the difference. ### Claim 3 (depends on 2) The display method according to claim 2, wherein the first guide image contains a numerical value showing the difference. ### Claim 4 (depends on 3) The display method according to claim 3, wherein a color of the numerical value changes according to the difference. ### Claim 5 (depends on 2) The display method according to claim 2, wherein the first guide image contains a first line segment and a second line segment, the first line segment shows the installation angle of the first display apparatus, and the second line segment tilts by an angle corresponding to the difference from the first line segment. ### Claim 6 (depends on 5) The display method according to claim 5, wherein a color of the second line segment changes according to the difference. ### Claim 7 (depends on 2) The display method according to claim 2, wherein the first guide image contains a second line segment, and a color of the second line segment changes according to the difference. ### Claim 8 (depends on 2) The display method according to claim 2, wherein the first guide image contains a first line segment, the first line segment shows the installation angle of the first display apparatus, and a color of the first line segment changes according to the difference. ### Claim 9 (depends on 5) The display method according to claim 5, further comprising displaying a second guide image, by the first display apparatus, for guiding adjustment of the installation angle of the second display apparatus, wherein the second guide image contains a third line segment, and the third line segment shows a reference for the installation angle of the second display apparatus. ### Claim 10 A display system comprising: a first display apparatus; and a second display apparatus, wherein the first display apparatus generates first angle information representing an installation angle of the first display apparatus based on a detection value of a sensor provided in the first display apparatus, the second display apparatus generates second angle information representing an installation angle of the second display apparatus based on a detection value of a sensor provided in the second display apparatus, and the second display apparatus reports information representing a difference between the installation angle of the first display apparatus represented by the first angle information acquired from the first display apparatus and the installation angle of the second display apparatus represented by the second angle information. ### Claim 11 A display apparatus comprising: a sensor detecting an installation angle of the display apparatus; and a processor programmed to execute generating second angle information representing an installation angle of the display apparatus based on a detection value of the sensor, receiving first angle information representing an installation angle of a display apparatus different from the display apparatus, and reporting information representing a difference between the installation angle represented by the received first angle information and the installation angle represented by the generated second angle information.
