I have an LCD screen 16x2 4 pin which I cant seem to print on. I use an arduino nano with the code LQFP32 and I have the wires connected as VCC > 5v GND > GND SDA > A4 SCL > A5 I can communicate fine with the LCD, I have ran scans to check if its connected and I am also able to control things …

The I2C backpack has a blue potentiometer which you adjust to optimise the display performance.
