Confirm it works, that is: with I2C-HD44780.
You have to configure "USE_I2C_LCD = 20x4" in the configuration.txt.
See docs.

Yes, I have "USE_I2C_LCD = 20x4" in the configuration. The output is still utilizing only 2 lines and 16 characters (16x2). The other lines/characters are unused/blank.
Can you clarify, by "Confirm it works", do you mean A. "I see it in the docs, so it should work", or B. "I'm personally using a 20x4 screen" ?
