I recently got a raspberry pi 4 (8GB) and a monitor. I have installed Kali linux 2023.2 and parrot sec os 5.3 but my 1920x 1080 monitor isn’t working with my raspberry pi 4, and keeps defaulting to 1824 x 984 when I run xrandr -s 1920 x 1080 I get the message “Size 1920 x 1080 not found in available in modes.” I have tried my screen with a micro SD with Ubuntu 22.04 installed and it works fine which has led me to believe that this is a problem in settings when using Kali and parrot sec os but the only option in settings is 1824 x 984 there isn’t any other option for screen size and custom profiles don’t work either. I tried adding custom screen resolutions using xrandr but that doesn’t seem to work either. Please check the below attached images of monitor.
Welcome to the forums
have you tried $ xrandr -q to see what resolutions are possible?
yesh all it shows is just one resolution which is “1824×984” and an error message which is as follows:
“Failed to get size of gamma for output default”
i fixed this issue in kali linux by editing these 3 lines in /boot/config.txt
dtoverlay=vc4-fkms-v3d
hdmi_group=2
hdmi_mode=82
but no luck with parrot security os
I do not know much about Raspberries so I do not know if you can force it.
xrandr --output VGA-1 --mode 1920 x 1080
Hi - I have the exact issue.
