Description

The DevicePixelRatio property returns the ratio of physical pixels per CSS pixel emulated for the specified mobile browser. For example, Apple devices with Retina displays (like iPhone 6) have the device pixel ratio of 2, which means that one CSS pixel is displayed using 4 physical pixels – 2 horizontally and 2 vertically.

This is the same value as specified in the Device Pixel Ratio column in Project Properties | Open Applications | Web Testing | Virtual Browsers (see Project Properties - Virtual Browsers Options).
