Power Suppy TFT Monitors

I start a new job shortly in the US and my son would like me to purchase at 19" Flat screen monitor as they a lot cheaper there than the UK.

My problem is what about the monitors power supply, am I right in thinking that it is 220 in the States and 240 here, will I have any problems or will they work okay.

I also want to buy a digital camera there for the family but I have concerns over the Battery Charger will it work okay in the UK.

Thanx in anticipation
