As answered by people managing Codility and DisplaySpan.
DisplaySpan's answer:
DisplaySpan combines three everyday multi-monitor fixes in a native Mac menu bar app: cursor movement across blocked screen edges, automatic restoration of saved display positions, and brightness control for supported screens. Brightness keys can target the display under your pointer. Display profiles stay on your Mac, and cursor or keyboard activity is not uploaded.
DisplaySpan's answer:
Choose DisplaySpan when your main frustrations are a cursor getting stuck between monitors, screen positions changing after reconnecting a dock, or brightness keys adjusting the wrong display. It puts these controls in one menu bar app, with a 3-day free trial and a one-time license starting at $9.90. Try it with your own setup first: third-party brightness requires Apple Silicon and a working DDC/CI connection, and layout restoration covers screen positions.
DisplaySpan's answer:
DisplaySpan is for Mac users working with two or more displays, especially people pairing a MacBook with an external monitor or regularly connecting to a dock. It is useful for developers, designers, remote workers, and anyone who wants smoother cursor movement, a repeatable desk arrangement, and convenient brightness control. It runs on macOS 14 or later.
