图解笔记本电脑利用VGA端口连接投影机或大屏幕液晶电

视

在培训、开会、教学时经常需要把笔记本连接投影机或者大屏幕液晶电视，让

投影机或

者电视演示笔记本的内容，两者连接过程非常简单。

一、了解VGA接口

图,:液晶电视后面的VGA接口

接口还有in和out之分，例如图,投影机VGA接口就有一个in和一个out，用

户切记不要把笔记本视频连线连接到VGAout去，如果接错信号口，这样不论你怎

么设置，投影机都不会为你“工作”的。

图,:VGA连线

当VGA线长度在15-20米时，投影机画面就会严重衰减，因此VGA连线不宜过

长，一般要控制在10米以内，家庭吊装投影机的用户同样需要注意这个问题。

二、连接好笔记本电脑到投影机或是液晶电视的连线

三、设置好笔记本分辨率

使用宽屏笔记本的用户不断增加，笔记本在连接比它分辨率低的投影机时，投

度虚化，分辨率相差越大，画面虚化程度越明显，一些与宽屏笔记本兼容性较差的

投影机甚至不能适应宽屏分辨率，导致无法显示。

如果投影机或电视出现“罢工”，当使投影切换功能键切换之后还是无法显示

的时候，可能就是计算机输入分辨率的问题了，这时只要把计算机的显示分辨率调

整到投影机允许的范围内即可，同时也需要注意投影机画面宽高比的设置。有时投

影画面虽然能显示，但是只是显示了电脑上的一部分图像，这时也可能是电脑的输

出分辨率过高造成的，用户可适当降低电脑分辨率再进行投影。连接投影仪的电脑

必须是安装了官方显卡驱动的电脑，这样电脑才能确保一定能投影。连接投影仪

的电脑的分辨率必须是低于或等于1024*768,刷新频率为60赫兹，可参考投影仪

或电视说明书。

四、搜索信号

打开投影机或电视机电源，投影机遥控板上有“Computer”或“input”之类

的按键搜索信号，电视遥控板上有“TV/AV”按键选择“VGA”即可。活用笔记本

不少用户把投影机与笔记本连接好后，开启投影机，但投影机扔不能显示笔记

本画面，这可能是笔记本与投影机连接的视频端口未被激活导致的，此时只要按住

笔记本电脑的Fn键，然后同时按下标识为LCD/CRT或显示器图标的对应功能键，

如上图的F4键进行切换,选择“双屏”即可。(根据笔记本的型号而定，看F1~F12

键上印有像小电脑、小屏幕的方块形的功能键):

华硕笔记本Asus?Fn+F8，另外戴尔Dell、苹果(fn+f8)

东芝TOSHIBA、夏普Sharp?Fn+F5

惠普康柏Compaq?Fn+F4富士Fujitsu?Fn+F10日立Hitachi?Fn+F7NEC、方

正、联想、三星、松下Panasonic、盖特威Gateway(fn+f3)还有几款笔记本电脑

的切换键则需要用到鼠标来进行切换。

方法:单击鼠标右键，将光标移动至“图形选项”，在出现的对话框中选择

“输入至”，再将光标移动到“(Intel)双显示制”，最后点击“显示器+笔记本电

脑”也就是最下面一个，将完成切换。(望各位教师熟练切换方法)

笔记本电脑外接显示设备时，通常有四种显示输出控制。需要多切换几次，切

换一次等3秒，一般情况:

笔记本液晶屏亮，外接显示设备亮

笔记本液晶屏亮，外接显示设备不亮

笔记本液晶屏不亮，外接显示设备亮

笔记本液晶屏不亮，外接显示设备不亮

另外，有可能碰到无法调整显示适配器的情况，请重新安装原厂的显卡驱动后

再行调整。笔记本连接需要注意两点:

1、笔记本BIOS中开启RGB接口

方法:在BIOS中开启在计算机启动时进入BIOS设置，设置笔记本的显示属性

(display)为both。一般都设置为自动状态，无须调节。

2、在显示属性中设置电脑双屏显示可分为两种模式:一种为镜像模式(复制模

式)，另一种是扩展模式。

当使用镜像模式时，笔记本电脑LCD和投影机屏幕显示完全相同。而使用扩展

模式时，投影机显示是主显示器(笔记本电脑LCD)的扩展、延伸。

在进行双屏设置时，一定要事先接好投影机或其他显示设备，否则将不能正确

设置。调出显示属性对话框，设置中选择多个监视器，即笔记本+投影仪。

五、声音:

如需要声音输出，请

将音频线插入相应的接口

即可，一般绿色为音频输

出接口(边上图标像耳机

形状)，红色为话筒麦克风

接口(边上图标像话筒形

状)。

同时注意音量是否静音或

调到适当大小，软件中的

音量是否适中。

六、注意事项:

防止投影仪的灯泡出现炸裂的现象;因为投影仪在工作状态下灯泡的温度会非

高，当突然断电风扇就会停止运转，灯泡突然热胀冷缩就会引起炸裂，所以当

我们关闭投

影仪后不要立即拔下电源，必须等到风扇停止运转后再拔下电源。
