声明:
GetSystemMetrics(
  nIndex: Integer {参数, 详见下表}
): Integer;

举例 - 获取屏幕分辨率:
var
  cx,cy: Integer;
begin
  {通过 GetSystemMetrics 函数获取屏幕分辨率}
  cx := GetSystemMetrics(SM_CXSCREEN);
  cy := GetSystemMetrics(SM_CYSCREEN);
  ShowMessageFmt('Width:%d; Height:%d', [cx,cy]);

  {通过 Screen 对象获取屏幕分辨率}
  cx := Screen.Width;
  cy := Screen.Height;
  ShowMessageFmt('Width:%d; Height:%d', [cx,cy]);
end;
