+    \title High-DPI Support in Qt Quick Controls 2
+
+    Qt Quick Controls 2 support Qt's cross-platform high-DPI scaling introduced in Qt 5.6.
+    The feature is opt-in, and can be enabled by setting the \c Qt::AA_EnableHighDpiScaling
+    application attribute in C++ before QGuiApplication is constructed:
+
+    \code
+    #include <QGuiApplication>
+    #include <QQmlApplicationEngine>
+
+    int main(int argc, char *argv[])
+    {
+        QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling); // <--
+        QGuiApplication app(argc, argv);
+        QQmlApplicationEngine engine;
+        engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
+        return app.exec();
+    }
+    \endcode
+
+    Alternatively, an environment variable \c QT_AUTO_SCREEN_SCALE_FACTOR=1 can be set
+    to enable automatic high-DPI scaling.
+
+    \warning \l {Qt Quick Controls}{Qt Quick Controls 1.x} are not compatible with Qt's
+    automatic high-DPI scaling. There is currently no available solution for high-DPI
+    support in applications wishing to mix Qt Quick Controls and Qt Quick Controls 2.
