## Attached Property Documentation

[read-only] Screen.logicalPixelDensity : real

The number of logical pixels per millimeter. This is the effective pixel density provided by the platform to use in image scaling calculations.

Due to inconsistencies in how logical pixel density is handled across the various platforms Qt supports, it is recommended to use physical pixels instead (via the `pixelDensity` property) for portability.

This QML property was introduced in Qt 5.1.
