Defensive position, said computer display (4,3)

read out
'computer display' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'defensive position said' is the wordplay.
'defensive position' becomes 'redoubt' (type of fort).
'said' shows a homophone (sound like).
'redoubt' sounds like 'READ-OUT'.
Can you help me to learn more?
(Other definitions for read out that I've seen before include "Retrieve data" , "retrieved message" , "Say aloud from a text" , "Visual data coming from a computer" , "Retrieve information" .)
