I think the monitor is havang a joke with you, or you are trying to have a joke with us.
The only thing I can think of is for you to install the drivers for the new monitor (most come with a cdrom for this). But of course you need to use the old one to see to install it, so if the old one dosen't work or you no longer have it, borrow a friend/relitive/cat's monitor and install the drivers, then plug in the new one, and it should work.
