A simple (or maybe not) question. What is the Compose Desktop equivalent to

val densityDpi = LocalContext.current.resources.displayMetrics.densityDpi

This only seems to work on Android or maybe I am just blind and don’t see the obvious.

does val density = LocalDensity.current help?

The code that initializes HiDPI is here, btw.
https://github.com/JetBrains/androidx/blob/jb-main/compose/ui/ui/src/desktopMain/kotlin/androidx/compose/ui/window/LayoutConfiguration.desktop.kt
But LocalDensity should be good enough to get that value in an application.

I want to get the physical DPI value and that does not seem to be possible without resorting to AWT methods.

val scaledDpi = Toolkit.getDefaultToolkit().screenResolution
val displayScalingFactor = LocalDensity.current.density.dp.value
val physicalDpi = displayScalingFactor * scaledDpi

I think the underlying issue is this: https://github.com/JetBrains/compose-jb/issues/531
