树莓派Kali系统 HDMI 修改屏幕分辨率_树莓派 hdmi 开机分辨率 一直是1080p

树莓派刷kali系统后开机连接到HDMI屏幕上面，发现屏幕分辨率太高导致什么都看不清，就像这样

 

 

后来上网找了很多资料都说是在设置->显示中进行分辨率的修改，但是我即便是登录了root账户也无法修改分辨率。

后来结合网上资料，然后自己摸索了一下，找到了HDMI调节屏幕分辨率的方法

1.把树莓派SD卡拔下来插电脑上

2.打开config.txt文件（刚刚安装没运行过的kali是没有这个文件的，推荐先运行一次）

3.添加一下指令，也可以直接修改文件中原有指令，不过记得把#号去掉

我的HDMI屏幕分辨率是480*320的，但是我喜欢设大一点，所以设置成1.5倍大小

framebuffer_width=720
framebuffer_height=480

hdmi_group=2
hdmi_mode=3
hdmi_ignore_edid=0xa5000080

hdmi_group和hdmi_mode的值对应想要调整的分辨率。另外一项“hdmi_ignore_edid”，是命令树莓派不检测HDMI设备的任何信息，只按照我们指定的分辨率输出。如果不加，树莓派可能仍会检测HDMI设备的分辨率，结果造成设置的分辨率无效。
记得去除命令前的#号

以下是CEA规定的电视规格分辨率。这些分辨率的hdmi_group=1。

H means 16:9variant (of a normally 4:3 mode).

4x means pixelquadrupled (i.e. higher clock rate, with each pixel repeated four times)

4.修改好config.txt后保存，将SD卡插回树莓派上就好了

 

明显清晰了很多呢
