4K Resolution Problem While Switching The Application From High to Low

Sebastian

Dear Friends,
I have a Qt application when i am trying to switching between the low resolution to high resolution then its a problem.what we want if we switch between low resolution to high resolution it should automatically adjust .so first i read about that i found Qt Supports the high resolution.

QApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
Or
QT_AUTO_SCREEN_SCALE_FACTOR=1

I tried the both ways the first one does not work.The second one is working but partially when i move from low resolution to high resolution(4K) then it adjust and if again i am moving back to high to low then it changes to bigger size.
Please let me know if any thing i am missing.
Waiting for your response guys.
TIA
