So I've spent a good amount of time Googling this subject and I've come up with some different answers so I was hoping to get some feedback here. I've ordered the Yamakasi O40USUT and it comes hardwired with a Korean plug. It may or may not include an adapter but I was reading on another forum that a simple converter that changes it to an American plug may not be good for the monitor and you might have to buy something that changes the voltage. I want to make sure I know what I need ahead of time because once the monitor arrives I'm not going to want to start research at that point, unable to use it.
Check the manufacturer's specs (on the monitor) if it works on 110V (or whatever your voltage is), as many devices do. You can chop off and rewire the plug yourself, but getting an adapter will probably be easier. I think they use German/French sockets in Korea, so an adapter with an European socket and US plug should do it.
But consider not buying the cheapest one sold on ebay, they aren't always safe.
If the monitor is 220V only, you'll probably need a transformer to convert the voltage.
If you are going from 110v to a 220v then it should be ok because it will only draw 110v still. If you had a US spec monitor which drew 110v then tried to plug it into the euro sockets delivering 220v you would possiblt blow something. I can only speak from exeperience from when I owned a japanese PS2 and I used a voltage converter jobby to switch it to 220v but when I took my UK devices to the states I had no such problem because the built in transformer thing will drop it down to 12v or 19v or what ever the monitor actually uses. Sorry for me technical words like jobby, I'm clearly not an electrical expert
Thanks for the help guys. The specs give this for the power:
Power Input: AC 100~240V 50/60HZ
Not sure exactly what that means but I would guess I'd be ok with a converter from the local Radio Shack or something if it doesn't come with one included.
AC (Alternating Current) 100~240V (It can operate at anywhere from 100V to 220V. American and european voltages.) 50/60HZ (The frequency of the voltage.)
Ah ha! Thanks! [=
