Crossword Genius

Check it's a lizard (7)

Ross

I believe the answer is:

monitor

I believe this is a double definition.

'check' is the first definition.
(synonyms)

'a lizard' is the second definition.
(I know that monitor is a type of lizard)

'it's' acts as a link.

(Other definitions for monitor that I've seen before include "Watch - lizard - warship - VDU" , "Sort of lizard" , "record" , "Observe over time" , "A television or computer screen" .)

I've seen this clue in The Daily Express.
