from gi.repository import Gdk
s = Gdk.Screen.get_default()
print(s.get_width(), s.get_height())

Answer 1

You can get the primary screen from the QApplication, which returns a QScreen object giving access to many useful properties:

import sys
from PyQt5 import QtWidgets

app = QtWidgets.QApplication(sys.argv)

screen = app.primaryScreen()
print('Screen: %s' % screen.name())
size = screen.size()
print('Size: %d x %d' % (size.width(), size.height()))
rect = screen.availableGeometry()
print('Available: %d x %d' % (rect.width(), rect.height()))

Note that the primaryScreen method is static, so if you've already created an instance of QApplication elsewhere in your application, can easily get a QScreen object later on like this:

screen = QApplication.primaryScreen()

Answer 2

from PyQt5.QtWidgets import QApplication, QWidget
self.desktop = QApplication.desktop()
self.screenRect = self.desktop.screenGeometry()
self.height = self.screenRect.height()
self.width = self.screenRect.width()
