Q. Here is the deal...
I have an IBM LCD monitor that I got on the cheap from Ebay, the issue was that it didn't have a base or a power supply.
Big deal, I thought because the plan was to wall-mount it and I had 6-7 old ac adapters lying around that would have roughly the same voltage and amperage.
So, now that I got it in the mail, I find that it requires a 12v 3.0 amp adapter. Unfortunately, all the adapters I have that provide enough amperage are all 19V or higher.
Back to the question, couldn't I just add a transformer inline with the output cable to step down the voltage to a level that will not fry the monitor?
Where could I find a step-down transformer that small?
The adapters I am looking to use are all old notebook adapters. I imagine these are too well regulated to work considering what you are all telling me.
The main point of this was to figure out a way to do it and avoid having to buy the adapter outright. There is a good level of satisfaction knowing that you were able to avoid spending money by doing things yourself.
I found a 15v 4A adapter, but again it is a notebook adapter. Looks like I will have to suck it up and buy a new one, unless anyone has any other ideas...

A. It depends.
If the adapters you have generate a regulated DC output, then trying to reduce the voltage by running the AC side off a transformer isn't going to be successful.
However, if the adapter produces an unregulated DC output, or an AC output, then if you can find the correct transformer it should work. For example, using a 24V adapter with a transformer sold to run 120V appliances off a 240V mains would give you the 2:1 ratio that you need. You might have to do some wiring. If the output of the adapter is AC, the step-down transformer can go on either the mains side or the output side of the adapter. If the output of the adapter is DC, you would have to put the step-down on the mains side.
I would be a little careful here, though. It is likely that the monitor needs a regulated DC supply, in which case you have to buy something that supplies the required voltage and current. Usually, monitors that I have seen come with a brick power supply similar to what is used for laptops, and those generally provide a high-current, regulated, DC output.
