Resolution Mapper v1.2

Bugfix release for virtual display cleanup and macOS arrangement restore failures.

Download

• ResolutionMapper-v1.2-macos-universal.dmg contains Resolution Mapper.app with a drag-to-Applications installer window
• Universal macOS build: Apple Silicon (arm64) and Intel (x86_64)
• Ad-hoc signed for local use

What's new

• Adds a small remove button on virtual display rows
• Adds Clear Virtuals for virtual displays managed by the current app session
• Mapping no longer fails just because macOS refuses display origin restore (1001)
• Shows a clear status when a visible virtual display belongs to an older app session and cannot be invalidated directly
• App version bumped to 1.2

Note

If old virtual displays were created by an older app process, quit Resolution Mapper or log out once to let macOS release them. New virtual displays created by v1.2 can be removed from the app UI.

Resolution Mapper v1.1

Resolution Mapper v1.1

This release focuses on keeping macOS display arrangement stable after an external monitor is disconnected and connected again.

Download

• ResolutionMapper-v1.1-macos-universal.dmg contains Resolution Mapper.app with a drag-to-Applications installer window
• Universal macOS build: Apple Silicon (arm64) and Intel (x86_64)
• Ad-hoc signed for local use

What's new

• Saves the physical monitor arrangement origin when you map a monitor
• Restores the saved display origin when the monitor reconnects
• Keeps the stable virtual display serial per physical monitor from v1.0 updates
• Applies display origin before and after mirroring so macOS has a better chance to preserve cursor movement direction
• App version bumped to 1.1

Note

After installing v1.1, arrange the monitor once in System Settings if needed, then press Map Monitor once so Resolution Mapper can save the correct arrangement origin for that monitor.

The app uses macOS virtual display APIs. If Gatekeeper blocks the downloaded app, open it with right click -> Open or allow it in System Settings -> Privacy & Security.
