使用说明

Windows 版本：

1. 复制代码保存为 扩展屏管理.ps1
2. 右键点击 -> "使用 PowerShell 运行"
3. 或打开 PowerShell 管理员模式运行

macOS 版本：

1. 复制代码保存为 扩展屏管理.sh
2. 终端执行：chmod +x 扩展屏管理.sh
3. 运行：./扩展屏管理.sh

功能特点：

• ✅ 查看显示器信息：显示分辨率和刷新率
• ✅ 切换模式：扩展/复制模式一键切换
• ✅ 主显示器设置：快速切换主显示器
• ✅ 分辨率调整：预设常用分辨率
• ✅ 跨平台支持：Windows 和 macOS 通用

高级功能（可扩展）：

如果需要更高级的功能,

1. 自动保存/恢复配置
2. 多显示器布局记忆
3. 一键切换工作模式（编程/设计/游戏）
4. 显示器DPMS电源管理

请告诉我具体需求,我可以帮你扩展脚本功能！
