I purchased a couple AMC2004A 20x4 lcd screens, I just hooked one up to test it and it works except that lcd.SetCursor only positions the column, and not the row, any number given for the row argument always prints on the top line. I tried forcing it to print on all lines by just giving it a string …

20x4 LCD Screen only prints to line 0 and 2...

Don't you need to call lcd.begin() to tell the library what size of display you have?
