Hi trilobyte
Draby is absolutely correct - Just plug it in and go (using a US power cord of course) ... The LCD will auto adjust to your local voltage (110v).
The label says it accepts all voltages between 90v and 240v plus it will work just fine at either 50hz or 60hz (US uses 60hz).
I'm using a 19" LCD monitor I purchased from Wal-Mart back in 2005 on my pc ... just changed the power cord to a UK one and all was well.
The worst thing that will happen is it won't switch on due to insufficient voltage ... BUT I bet it works just fine :-)
