Addendum
PM 7600 has Db-15 male-just as your cable(fits).Your ordered? cable has HD-15 male(VGA) on the other end(the piczure does not show that,but description). Your monitor should have HD-15 female,look for that at(picture 1) at:

IF it has such a connector it would fit ,too. Otherwise you would need a gender changer HD-15(cheap).
For both pinouts(VGA,DB 15) you may look at:

All my MACs have DB-15 female.
You will see wether you get problems with resolutions.
Display/Monitor-cable is a DB-15 male on both ends-that's what I've got-and some adapters Mac/VGA
That's all from me-Good luck
