# CGGetDisplaysWithPoint(_:_:_:_:) Provides a list of online displays with bounds that include the specified point. ``` func CGGetDisplaysWithPoint(_ point: CGPoint, _ maxDisplays: UInt32, _ displays: UnsafeMutablePointer?, _ matchingDisplayCount: UnsafeMutablePointer?) -> CGError ``` ## Parameters `point` The coordinates of a point in the global display coordinate space. The origin is the upper-left corner of the main display. `maxDisplays` The size of the `displays` array. This value determines the maximum number of displays the list includes. `displays` A pointer to storage you provide for an array of display IDs. On return, the array contains a list of displays with bounds that include the point. If you pass `NULL`, on return the display count contains the total number of displays with bounds that include the point. `matchingDisplayCount` A pointer to a display count variable you provide. On return, the display count contains the actual number of displays the list includes in the `dspys` array. This value is at most `maxDisplays`. ## Return Value A result code. To interpret the result code, see [`CGError`](/documentation/CoreGraphics/CGError). ## Discussion If the `displays` array is `nil`, this function ignores the `maxDisplays` parameter. If the `maxDisplays` parameter is `0`, this function ignores the `displays` array. In any case, this function fills in the `matchingDisplayCount` pointer with the number of displays that contain the specified point. --- Copyright © 2026 Apple Inc.
