I can only assume that the Dell people were smart enough to assume someone
would short out the power output line as you just did. And I can assume that
they probably put a fuse in their internal Power supply that would protect
that Power line. Open her up and check for a fuse.
If your lucky, you blew it out. If your not lucky, you took out the Monitor

I connected an 9.4Vdc 400mA power supply for external pc speakers to a
12V power supply line from the back of my Dell 20" FP LCD monitor
intended for an optional "speaker bar" that Dell sells. Suffice to
say, neither the monitor nor the dc power supply are working. Anyone
know what to look for to repair the monitor? Is it salvageable?
Possible just some components near the power supply outputs needing
replacing?
