Will OCUK accept a return?
Nothing is damaged and everything will be repacked exactly as I received it.
Is it possible to just post it back and receive a refund?
Are you sure you won't be able to adjust to the new screen? First couple of days with a new monitor are always strange.
EDIT: oh and BTW I don't know what OC's return policy is like, but I belive you have few days to return the item if you are not happy (call them, I might be wrong)
