I've heard that in order to use LX screens in an MX you need to have the meter recalibrated since the screens are brighter and the meter reads from behind the screen. This could probably be confirmed through experimentation. It also raises the question are the LX screens consistent in there brightness or the recalibration only be valid for certain screens?
