Stalybridge has the white boards on 1-3, as well as the addition of 3 new square white LED departure boards around the station (two at the top of the 1-3 ramp, one on the wall of the booking office, designed to be viewed from outside the building) and some portrait monitors for departures to replace the old landscape ones. A help point was also replaced.
P4 also has two sets of portrait monitors, P5 has nothing yet.
The two boards on P4 are nice but if they could offset the timing for the annoying 'information' screen about engineering works etc, so the boards constantly showed departure information it'd be better.
The white LED boards smooth scroll, and are capable of showing diagram formation information, and scheduled calling point times.
I have found the diagram information to be unreliable, especially for 2x185.
