When I was reseaching buying a plasma, I found that they were all NTSC/PAL capable. They are all so expensive, that buyers expect all the bells and whistles, and this is one of them. I would be extremely surprised if it wasn't multi-format. Similarly I found that the majority of them were universal voltage. The main culprit that claims different voltage operation is Panasonic. Of course sometimes this is just a bluff to discourage grey imports, and you can in fact run a machine stickered at 115v on 220v. But you have to be very very brave to try it out... and I definitely wouldn't recommend it.

What is the model you are looking to buy ?
