python -- get native screen resolution

pywin32

method one

Use the win32api.GetDeviceCaps() method to get the display resolution.
Use the win32api.GetDC() method to get the device context handle of the entire screen, and then use the win32api.GetDeviceCaps() method to get the horizontal and vertical resolutions. Finally, you need to call the win32api.ReleaseDC() method to release the device context handle.

	import win32api
	import win32con
	
	hdc = win32api.GetDC(0)
	screen_width = win32api.GetDeviceCaps(hdc, win32con.HORZRES)
	screen_height = win32api.GetDeviceCaps(hdc, win32con.VERTRES)
	win32api.ReleaseDC(0, hdc)
	print(f"屏幕分辨率为：{screen_width} x {screen_height}")

Method Two

Use the win32api.EnumDisplayMonitors() method to enumerate all monitors and get their resolutions.
This method returns a list where each element represents a rectangular area of ​​the display. From the rectangular area, the width and height of the display can be calculated to determine its resolution.

import win32api
import win32con

def get_monitor_info():
monitors = []
monitor_enum_proc = lambda hMonitor, hdcMonitor, lprcMonitor, dwData: monitors.append(lprcMonitor)
win32api.EnumDisplayMonitors(None, None, monitor_enum_proc, 0)
return monitors

monitors = get_monitor_info()
for i, monitor in enumerate(monitors):
width = monitor[2] - monitor[0]
height = monitor[3] - monitor[1]
print(f"第{i+1}个显示器分辨率为：{width} x {height}")

method three

import win32api

screen_width = win32api.GetSystemMetrics(0)
screen_height = win32api.GetSystemMetrics(1)
print(f"屏幕分辨率为：{screen_width} x {screen_height}")

Pillow

Note that this method requires the Pillow module to be installed. It can be installed by running pip install Pillowthe command. Use the grab() method of the ImageGrab module to get a screenshot of the entire screen, then read the width and height from the screenshot to get the screen resolution.

from PIL import ImageGrab

screen = ImageGrab.grab()
screen_width, screen_height = screen.size
print(f"屏幕分辨率为：{screen_width} x {screen_height}")

ctypes

It should be noted that this method is only applicable to the Windows operating system, and does not install any third-party libraries. Get the screen resolution by calling the GetSystemMetrics function in the Windows User Interface Library.

import ctypes

user32 = ctypes.windll.user32
screen_width = user32.GetSystemMetrics(0)
screen_height = user32.GetSystemMetrics(1)
print(f"屏幕分辨率为：{screen_width} x {screen_height}")

pygetwindow

import pygetwindow as gw

screen = gw.getWindowsWithTitle('')[0]
screen_width, screen_height = screen.size
print(f"屏幕分辨率为：{screen_width} x {screen_height}") 

Running this code will output the screen resolution. Note that pygetwindowthe module needs to be installed. It can be installed by running pip install pygetwindowthe command.

screeninfo

from screeninfo import get_monitors

for m in get_monitors():
print(f"屏幕分辨率为：{m.width} x {m.height}")

Running this code will output the screen resolution. Note that screeninfothe module needs to be installed. It can be installed by running pip install screeninfothe command.

tkinter

import tkinter as tk

root = tk.Tk()
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
print(f"屏幕分辨率为：{screen_width} x {screen_height}")

Running this code will output the screen resolution. It should be noted that tkinterit needs to work properly in a GUI environment, so this method may not be suitable for some applications or server environments.

pyautogui

import pyautogui

screen_width, screen_height = pyautogui.size()
print(f"屏幕分辨率为：{screen_width} x {screen_height}")

Running this code will output the screen resolution.
