PyQt5 GUI -- Resolution Inconsistency issue in Desktop and Laptop

[Shruthe]

Hello,

I am developing a GUI using PyQt5. Whenever I connect my laptop to an extended monitor via an HDMI cable and disconnect it and run my GUI on laptop the font size of all of the Buttons become too small making it too tuff to read.

I have tried using -
QApplication.setAttribute(Qt.AA_EnableHighDpiScali ng)
QApplication.setAttribute(Qt.AA_UseHighDpiPixmaps)

But it still does not help with the issue.

All the GUI components i have created to VBox or HBox layouts.

Please note that this issue gets resolved once i restart my laptop and re-run the GUI.

Can you please help me in resolving this issue.

You try this way. I think so.

import sys
from PyQt5.QtWidgets import QApplication
from PyQt5.QtCore import Qt

# ??t các thu?c tính DPI **tr??c** khi t?o QApplication
QApplication.setAttribute(Qt.AA_EnableHighDpiScali ng, True)
QApplication.setAttribute(Qt.AA_UseHighDpiPixmaps, True)

app = QApplication(sys.argv)
