Android: Display count return as "1" in dual display setup



  • Hi,

    Platform : iMX6Q SABRE-AI,
    Using Android Marshmallow and QT : 5.7
    we have HDMI and LVDS (dual display) connected to imx6 board.

    //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
    int iScreenCount = QGuiApplication::screens().size();
    qDebug("[QT_ANDRO] ScreenCount--->%d",iScreenCount);
    ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

    Above code returns "iScreenCount" =1 , even-though we have connected HDMI and LVDS display to imx6 board.

    ///////////////////////////////////////////////////////////////
    foreach (QScreen *screen, QGuiApplication::screens()) {
    qDebug() << "[QT_ANDRO] Connected Screen Name" << screen->name();
    }
    ///////////////////////////////////////////////////////////
    also we are getting "screen->name()" as "empty".

    Please comment about this.

    Thanks

    @vineesh Do both displays work?



  • Yes.
