设置显示器分辨率的执行函数，注意,系统不支持的显示模式不能选,否则,准备用安全模式重启动吧.API函数EnumDisplaySettings可以选择系统支持的模式,自己去写吧,也很简单。

　　代码中的Or DM_DISPLAYFREQUENCY属性率的更改还是没办法，不过不加入此DM_DISPLAYFREQUENCY这个参数，只要系统支持，应该不会更改刷新率的。-Set the display resolution to execute the function, note that the system does not support the display mode can not be selected, otherwise, ready to restart in safe mode. API function EnumDisplaySettings the system support mode, to write, is also very simple.

Or, DM_DISPLAYFREQUENCY code attribute the rate of change or not, but not to join this DM_DISPLAYFREQUENCY this parameter, as long as the system supports should not change the refresh rate.
