Character LCD 40x2 I2C

[hjfisch]

I've a 40x2 I2C Character LCD , but I can only see 16 digits in 16x2 or 20 digits in 20x4 . There is no 40x2 setting in system . Is there any possibility to change it ?

20x4 settings

I'm quite satisfied with 4x20 setting for my 2x40 so far , but scrolling for titles longer than 20 digits would be nice .

@rern You add 20x2 not 40x2 .
But 20x4 is working ok for me to use the whole display. It divides the display in 20 x 2+20 x 2 .
And as I said "scrolling text" would be nice if more than 20 digits are used .
