Update in the System via the Terminal by running the following commads:
sudo apt update
sudo apt full-upgrade
Edit in the Terminal the config.txt configuration file by entering the command:
sudo nano /boot/firmware/config.txtUnder [all] add:
dtoverlay=dwc2,dr_mode=host
Run in the Terminal:
sudo raspi-configEdit:
Interfacing Options → I2C → Enable
Install the DDCUTIL application utility through the Terminal:
sudo apt install ddcutil -y
Check if the Utility is installed properly by running the command in the Terminal.
sudo ddcutil detect
sudo ddcutil setvcp 10 10
sudo ddcutil setvcp 10 100
