My website is showing in the wrong resolution?

Fully Kiosk Browser doesn’t select or force any screen resolution. Note that devicePixelRatio bigger than 1 can be set for your high resolution screen by the Android Webview. This affects the CSS pixel size reported by window.screen.width and window.screen.height. We are unable to change this by our app. Check you have the latest Android Webview available on your device and let your web developers learn in this training and this answer how to support high resolution screens (FullHD, 4K) properly.
