Does SamplerBox work with 20 X 4 LCD screens?

Hi Hans,
Yes, it outputs 16x2 to the 20x4 screen while using:
USE_I2C_LCD = True

The output shows on the Top 2 lines, while the bottom 2 lines are blank (as well as the last 4 characters), eg:

xxxxxxxxxxxxxxxx____
xxxxxxxxxxxxxxxx____

Changing to "USE_I2C_LCD = 20x4" as the Guest recommended results in a blank screen.

Upon re-reading the Guest's post, I think by "Confirm it works", they may have intended to say "Make sure your screen is functional", rather than "Yes I am confirming that 20x4 works" ?

If you have an alternate build, I can test it on my screen.
