好吧，这个我也弄一个专贴吧。
这样小白直接用现成的就OK了：
这个教程，适用于你的显示设备是HDMI接口、DVI接口、VGA接口

一、config.txt在哪里，如何修改？

1、将装好系统的SD卡，插入笔记本或者读卡器
2、进入SD卡所在盘符，一般为H盘
3、就能看到config.txt 文件了。
4、然后打开，进行内容编辑吧。。。。

二、好了不多数，修改好了的config.txt代码如下（直接复制，粘贴到SD卡里面的config.txt文件里面，保存即可）：

hdmi_ignore_edid=0xa5000080
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=4
hdmi_drive=2
config_hdmi_boost=4
sdtv_mode=2
arm_freq=800

复制代码

简单点说，这个参数：hdmi_mode=4 是你显示器的分辨率，一般改为16最为恰当。可以根据自己的显示器情况调节，具体如何调节看这个：

DMT分辨率

以下是计算机显示器使用的分辨率。
这些分辨率的hdmi_group=2。
