Boring outside is different (7)

I believe the answer is:

tedious

'boring' is the definition.
(I know this)

'outside is different' is the wordplay.
'is different' is an anagram indicator.
'outside' with letters rearranged gives 'TEDIOUS'.

(Other definitions for tedious that I've seen before include "Banal" , "drab" , "Wearisome, boring" , "Humdrum" , "Dull as ditchwater" .)

I've seen this clue in The Irish Independent.
