Just an FYI for anyone measuring the DC output of the brick...it's a fairly useless measurement without a load on the output. You'd have to take the measurement while the brick is hooked to the monitor for any kind of useful measurement. And even if you still got 24 volt reading, it still doesn't mean everything is good. By running at half the input voltage you are running twice the current through the front end of the power supply and so if the parts are not rated for that...you could still get early failures.
Most of these supplies are pretty generic and so the parts could easily be rated for 120v and the label just didn't reflect that. Or the parts really could only be rated for 240v operation. No way of knowing without opening up the psu and inspecting...
