DMChangeres.x32免费插件，使用比较简单，下面这段简短的程序已足以实现上述功能，而且还可恢复显示器刷新率。因为是免费的你自己找找看吧,是dmtools一系列的
on startMovie
global oldRes
set oldRes = changeRes([800,600])
(the stage).rect=rect(0,0,800,600)
end
on stopMovie
global oldRes
changeRes(oldRes)
end
用DMChangRes就可以很方便的解决这个问题。这个小巧的Xtra可以在www.dmtools.com下载，也可以在http://www.ccidnet.com/soft/cce/20010903.htm下载。安装DMChangResV1.0很简单，只需将DMChangRes.X32拷贝到你的Director Xtras文件夹。这个Xtra将在Lingo中增加一个新的函数ChangRes，凭借这个函数，你可随心所欲地更改用户端的屏幕分辨率。
运行Director 8.0，在Movie Script中输入如下程序：
on startMovie
global oldRes
set oldRes = changeRes([800,600])
end
该段程序首先在电影脚本中申明一个全局变量oldRes，用于保存用户当前的分辨率信息。函数changeRes([800,600])将屏幕分辨率改为800×600，同时返回用户原来的分辨率，保存在变量oldRes中。
在舞台中放置三个按钮：按钮1、按钮2、按钮3，并使它们的Text属性分别为640×480、800×600和1024×768。放置它们的位置如图所示：
在第10帧处加入帧脚本：
on exitFrame me
go to the frame
end
下面我们为这三个按钮分别加入相应cast member script ：
on mouseUp
changeRes([640,480])——这里的数字对应于按钮的Text属性
end
这样，当我们按下按钮之后，屏幕分辨率就产生相应的变化。
切记：演示作品结束之后，将分辨率恢复到先前的状态。用户一般不喜欢有人更改自己电脑的设置。只要最后在电影脚本中加入以下语句即可实现该功能：
on stopMovie
global oldRes
changeRes(oldRes)
end
如果同时还要改变屏幕颜色位数，参见lingo自带的函数the colorDepth。
