UPDATE:
All of my copies of the following are 10-1/2" tall, rather than 11" as indicated in the description on the front cover of each Screen and in the Descriptions in the Acaeum Index.
The 4th, 5th, 5th+, and 6th prints of the TSR
DM Screens.
I have also dug out three copies of the Ninth Print and all three sets (including the module Terrible Trouble at Tragidore) are 10-1/2" tall.
I do not have a copy of it, but I suspect the 4th+ print is also 10-1/2" tall.
My 4th Print has no lamination inside either screen, nor any overlap from the front.
My copy of REF 1 (Stock 9148) Dungeon Master Screen & Master Index is also 10-1/2" tall.
My copies of 9457 (Fighter's Screen) and 9468 (Wizard's Screen) are 10-3/4" tall.
The Acaeum Index does not list the dimensions of the later prints (after the 4th) listed in this thread.
Maybe this is not a significant enough difference to address...
