£6,
As you rightly say, the 737-436 has the facility to allow different tilts and different ranges to be displayed on each side. Other models of 737 did not. The Scud sticks particularly in the mind due to the screen which sat just ahead of the throttle quadrant and used to show coastlines far better than embedded CBs. (I remember a story of a crew - not sure which company - who removed it in flight once and had to use the fire axe to smash it to bits when it got stuck and they realised they couldn't set TOGA! - I digress.)
Anyway, as I meant to say before I rudely interrupted myself, the A319 also has the facility for different range and tilt on each display. V. useful.
