班班通电脑第一次使用设置电脑显示器与电视机同屏显示方法如下：
1． 第一次首先要设置电视机信号源 信号源一般是HDMI 2或则 HDMI 3
如下图1-1：点击电视机右下角触控快捷键白色部位，会出现1-2图菜单选项

图1-1
出现如下1-2图时 点击 HDMI 两下 切换成HDMI 2 信号源 或则 HDMI 3信号源，（信号源以插线为准一般都是HDMI 2）

2.电视机信号源切换好后这时电视机应该和电脑显示器同屏了但不同步，所以接下来是设置电脑与电视同屏显示如图显示器只显示个桌面背景无图标

3.出现无图标时 移动鼠标直到桌面上出现鼠标时 右击鼠标会出现右键菜单如下图3-1
然后选择屏幕分辨率会出现3-2图

3-1图
打开屏幕分辨率设置界面时会出现如下图3-2图显示，这里只需要设置多显示器栏中把扩展这些显示 改成复制这些显示然后点击确定。

![](https://wkrtcs.bdimg.com/rtcs/image?w=551&md5sum=f5058a33c5dfc949297ca671545469e9&sign=2c27c10348&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=79&ipr={"t":"img","w":"551","h":"743","dataType":"jpeg","c":"word/media/image6.png","imgOriW":3120,"imgOriH":4208})
设置好上述所有设置后屏幕分辨率界面就如下图所设置。分辨率设置为1024*768

此时显示器同屏显示设置完成
