Raspberry pie Kali system HDMI modifies screen resolution

Raspberry pie brush kali After the system is powered on, connect to HDMI On the screen , I found that the screen resolution is too high to see anything clearly , Just like this.

 

Later, I found a lot of information on the Internet and said it was setting -> Modify the resolution in the display , But even if I log in root The resolution of the account cannot be modified .

Later, combined with online materials , Then I fumbled for it , eureka HDMI How to adjust the screen resolution

1. Raspberry pie SD Unplug the card and plug it into the computer

2. open config.txt file （ Just installed and not run kali There is no such document , It is recommended to run once ）

3. Add a command , You can also directly modify the original instructions in the file , But remember to # Remove the number

my HDMI The screen resolution is 480*320 Of , But I like to make it bigger , So set it to 1.5 Multiple size

framebuffer_width=720
framebuffer_height=480

hdmi_group=2
hdmi_mode=3
hdmi_ignore_edid=0xa5000080

hdmi_group and hdmi_mode The value of corresponds to the resolution you want to adjust . Another item “hdmi_ignore_edid”, Ordered raspberry pie not to detect HDMI Any information about the device , Output only at the resolution we specify . If not , Raspberry pie may still detect HDMI Device resolution , As a result, the set resolution is invalid .
Remember to remove the before the command # Number

Here are CEA Specified TV specification resolution . These resolutions hdmi_group=1.

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

2x means pixeldoubled (i.e. higher clock rate, with each pixel repeated twice)

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

4. Modify config.txt After saving , take SD Just put the card back on the raspberry pie

 

Obviously a lot clearer
