Why FullHD is not FullHD in Boot2Qt (Apalis iMX8)?

[VitaliyBortsov]

Hello.
I am using Toradex Apalis iMX8 SOM on Apalis Evaluation Board. I connected FullHD display using HDMI->DVI adapter to evaluation board. I set the jumper for I2C to read EDID from display. Monitor show that resolution is 1920x1080@60.
I use Boot2Qt 5.14.1 image downloaded from my Qt account page.

Now I note that very simple QML program show that resolution is 960x540 instead of 1920x1080. What should I do to set correct resolution?

import QtQuick 2.14
import QtQuick.Window 2.14

Window {
    visible: true
    width: 1920
    height: 1080
    title: qsTr("Hello World")

    Row {
        id: mainScreen
        anchors.fill: parent
        Rectangle {
            id: control
            width: 100
            height: parent.height
            border {
                color: "black"
                width: 1
            }
            Text {
                width: parent.width
                horizontalAlignment: Text.AlignHCenter
                font.pointSize: 8
                font.bold: true
                text: "Control"
            }
        }
        Rectangle {
            id: plot
            width: 860 // on Desktop, second rectangle fill the rest of screen with value of 1820, but in Apalis iMX8 second rectangle is fully shown with 860
            height: parent.height
            border {
                color: "red"
                width: 1
            }
            Text {
                width: parent.width
                horizontalAlignment: Text.AlignHCenter
                font.pointSize: 10
                font.bold: true
                text: "Plot"
            }
        }
    }
}

I discover that problem is in default template from wizard while I create new QML Quick Application (main.cpp file).

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    if (qEnvironmentVariableIsEmpty("QTGLESSTREAM_DISPLAY")) {
        qputenv("QT_QPA_EGLFS_PHYSICAL_WIDTH", QByteArray("213"));
        qputenv("QT_QPA_EGLFS_PHYSICAL_HEIGHT", QByteArray("120"));

        QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    }

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

If I remove first if block then resolution is OK.
