This is the same as the value returned by Window.devicePixelRatio, except that Window.devicePixelRatio:
- always returns the device pixel ratio for the current screen.
- also includes scaling of the window itself, i.e., page zoom (at least on some browser implementations).

A number.
Examples
js
const screenDetails = await window.getScreenDetails();
// Return the device pixel ratio of the first screen
const screen1DPR = screenDetails.screens[0].devicePixelRatio;
