Error's back due to a false display of data (4-3)

I believe the answer is:

read-out

'display of data' is the definition.

'error's back due to a false' is the wordplay.
'back' says to take the final letters.
'false' indicates anagramming the letters.
The last letter of 'error' is 'r'.
'due'+'to'+'a'='duetoa'
'duetoa' with letters rearranged gives 'eadout'.
'r'+'eadout'='READ-OUT'

I've seen this clue in The Telegraph.
