I want to say that it will show 16 rows maybe.

I know that it will not show 18 rows at one time.      Even if it doesn't show 16 at once you can set it to alternate back and forth automatically for a set interval of time.     


Also, every single thing about the FMX is better than a 750.    Well, except for the physical size of it if you're in a cab that is limited for space.
