获取屏幕所有支持的分配律

在Windows平台上，获取屏幕的所有支持分辨率（也称为视频适配器的“显示模式”列表）通常涉及到系统级别的操作，可以利用Windows API中的相关函数来实现。其中一个常用的函数是`EnumDisplaySettingsW`，它可以返回当前显示器上所有可用的显示设置信息。

下面是一个简单的示例，展示如何使用Python的ctypes库来获取屏幕支持的所有分辨率：

import ctypes
from win32con import ENUM_CURRENT_SETTINGS, ENUM_REGISTRY_SETTINGS, ENUM_DESKTOP_SETTINGS

# 导入必要的库
user32 = ctypes.windll.user32
kernel32 = ctypes.windll.kernel32
kernel32.SetThreadExecutionState(kernel32.THREAD_SUSPEND_RESUME | kernel32.THREAD_GET_CONTEXT)

# 定义DEVMODE结构体
class DEVMODE(ctypes.Structure):
    _fields_ = [
        ('dmDriverExtra', ctypes.c_long),
        ('dmFields', ctypes.c_ulong),
        ('dmLogPixels', ctypes.c_long),
        ('dmBitsPerPel', ctypes.c_short),
        ('dmPelsWidth', ctypes.c_ulong),
        ('dmPelsHeight', ctypes.c_ulong),
        ('dmDisplayFlags', ctypes.c_ulong),
        ('dmColor', ctypes.c_ulong),
        ('dmDuplex', ctypes.c_ulong),
        ('dmYResolution', ctypes.c_ulong),
        ('dmTTOption', ctypes.c_ulong),
        ('dmCollate', ctypes.c_ulong),
        ('dmFormName', ctypes.create_unicode_buffer(32)),
        ('dmLogPixelsPerInchX', ctypes.c_ulong),
        ('dmLogPixelsPerInchY', ctypes.c_ulong),
        ('dmBitsPerPixel', ctypes.c_ulong),
        ('dmPanningWidth', ctypes.c_ulong),
        ('dmPanningHeight', ctypes.c_ulong),
        ('dmDisplayFrequency', ctypes.c_ulong),
        ('dmICMMethod', ctypes.c_ulong),
        ('dmICMIntent', ctypes.c_ulong),
        ('dmMediaType', ctypes.c_ulong),
        ('dmDitherType', ctypes.c_ulong),
        ('dmReserved1', ctypes.c_ulong * 14),
        ('dmReserved2', ctypes.c_ulong * 11),
        ('dmDriverId', ctypes.c_wchar_p * 32),
        ('dmErrorCorrection', ctypes.c_ulong),
    ]

def get_display_modes():
    modes = []
    
    dm = DEVMODE()
    dm.dmSize = ctypes.sizeof(dm)
    
    while True:
        success = user32.EnumDisplaySettingsW(None, ENUM_CURRENT_SETTINGS, ctypes.byref(dm))
        
        if not success or dm.dmDriverExtra == 0:
            break
        
        modes.append({
            'width': dm.dmPelsWidth,
            'height': dm.dmPelsHeight,
            'refresh_rate': dm.dmDisplayFrequency,
            'description': dm.dmDeviceString,
        })
        
    return modes

# 调用函数并打印结果
display_modes = get_display_modes()
for mode in display_modes:
    print(f"分辨率: {mode['width']}x{mode['height']}, 刷新率: {mode['refresh_rate']} Hz")

# 确保线程恢复之前结束操作
kernel32.SetThreadExecutionState(kernel32.THREAD_NO_SUSPEND)
