How do I get monitor resolution in Python?

On Windows:

from win32api import GetSystemMetrics

print("Width =", GetSystemMetrics(0))
print("Height =", GetSystemMetrics(1))

If you are working with high resolution screen, make sure your python interpreter is HIGHDPIAWARE.

Based on this post.

Taken directly from an answer to the post How can I get the screen size in Tkinter?,

import tkinter as tk

root = tk.Tk()

screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()

I created a PyPI module for this reason:

pip install screeninfo

The code:

from screeninfo import get_monitors
for m in get_monitors():
    print(str(m))

Result:

Monitor(x=3840, y=0, width=3840, height=2160, width_mm=1420, height_mm=800, name='HDMI-0', is_primary=False)
Monitor(x=0, y=0, width=3840, height=2160, width_mm=708, height_mm=399, name='DP-0', is_primary=True)

It supports multi monitor environments. Its goal is to be cross platform; for now it supports Cygwin and X11 but pull requests are totally welcome.

In Windows, you can also use ctypes with GetSystemMetrics():

import ctypes
user32 = ctypes.windll.user32
screensize = user32.GetSystemMetrics(0), user32.GetSystemMetrics(1)

so that you don't need to install the pywin32 package; it doesn't need anything that doesn't come with Python itself.

For multi-monitor setups, you can retrieve the combined width and height of the virtual monitor:

import ctypes
user32 = ctypes.windll.user32
screensize = user32.GetSystemMetrics(78), user32.GetSystemMetrics(79)
