Will this damage anything?

correct polarity?

YES

If the polarity is correct, it definitely won't harm the "transformer", and I don't see how the monitor would be damaged either. I've repaired thousa nds of monitors with bad caps, and the resulting low voltage *and* ripple n ever bothered the monitors. I don't know if your monitor will start 8 volts low, and my guess is that it won't, but try it anyway.

It won't hirt anything,but the monitor may not start either. YOu can use several D size batteries or even smaller rechargabel batteries in series with the power supply to make up the voltage. They will not last long, so make this a quick test.

I like it. Perhaps add a fuse as well, while at it.

It probably needs the 24volts. There's no reason to specify a high voltage if it's not needed.

There is no expectation that the voltage might come from a variety of sources, in this case the power supply is external either because it was easier to get UL approval with the external supply, or perhaps because the supply might fail and it's easier to change the power supply if it's external. So they picked the needed voltage in the first place.

Keep looking. Ever since the move to switching supplies rather than 60Hz transformer based power supplies, the world is alive with no longer needed external power supplies, and they all have good current rating, and offer a wide selection of voltages. If the first one you find isn't the right voltage, keep looking, chances are good you'll find one in the garbage or at a friend's place, they no longer needing it. I'm sure I've pulled

24vdc supplies out of tossed out inkjet printers (they tend to need a higher voltage) so that's another place to look.

The big issue is to make sure you wire it properly so the polarity is right for the monitor.

Often the same electronic equipment is used in several countries. They all have differnant kinds of power and plugs. It is easy to use a differant external supply instead of building differant ones into the equipment.
