如何在Python中获得监视器分辨率？
获取监视器分辨率的最简单方法是什么（最好是元组） 在Windows上：如何在Python中获得监视器分辨率？,python,screen,resolution,Python,Screen,Resolution,获取监视器分辨率的最简单方法是什么（最好是元组） 在Windows上： from win32api import GetSystemMetrics print("Width =", GetSystemMetrics(0)) print("Height =", GetSystemMetrics(1)) 如果您使用的是高分辨率屏幕，请确保您的python解释器是HIGHDPIAWARE 基于post.使用Linux，最简单的方法是执行bash命令 xrandr | grep '*' 并使用re
from win32api import GetSystemMetrics
print("Width =", GetSystemMetrics(0))
print("Height =", GetSystemMetrics(1))
基于post.使用Linux，最简单的方法是执行bash命令
xrandr | grep '*'
此外，您还可以通过PyGame:执行此操作。如果您使用的是wxWindows，您只需执行以下操作：
import wx
app = wx.App(False) # the wx.App object must be created first.
print(wx.GetDisplaySize()) # returns a tuple
在Windows中，您还可以将ctypes用于： 这样您就不需要安装pywin32软件包； 它不需要Python本身没有的东西 对于多监视器设置，您可以检索虚拟监视器的组合宽度和高度：
import ctypes
user32 = ctypes.windll.user32
screensize = user32.GetSystemMetrics(78), user32.GetSystemMetrics(79)
为了完整性，Mac OS X
import AppKit
[(screen.frame().size.width, screen.frame().size.height)
for screen in AppKit.NSScreen.screens()]
>>> screen = os.popen("xrandr -q -d :0").readlines()[0]
>>> print screen
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920
>>> width = screen.split()[7]
>>> print width
1920
>>> height = screen.split()[9][:-1]
>>> print height
1080
>>> print "Current resolution is %s x %s" % (width,height)
Current resolution is 1920 x 1080
#!/usr/bin/python
import Xlib
import Xlib.display
resolution = Xlib.display.Display().screen().root.get_geometry()
print str(resolution.width) + "x" + str(resolution.height)

如果专门使用
QtPySidefrom PySide import QtGui

screen_rect = app.desktop().screenGeometry()
width, height = screen_rect.width(), screen_rect.height()
我在下面的一个项目中使用了一个get_screen_解析方法，这基本上是一个导入链。您可以根据需要进行修改，方法是移除不需要的零件，并在链中向上移动更可能的端口
