Just so we have more info:

Did you replace a John Deere monitor or a Dickey John monitor?

Do you know if you have a 2 LED "eye" seed tube sensors or a 3 LED "eye" seed tube sensor(high rate)?

Did you "build" a new configuration with your tractor attached to your planter and use that configuration while planting?

     (Do you get a "Green Checkmark", when you set your configuration?) = first screen, towards upper right-hand corner area

I assume you have your tractor and its measurements listed under Equipment.(programmed inside monitor)

I assume you have your planter and its measurements listed under Equipment, also.
