Can it be used as a monitor in Europe?
I understand it can not display PAL, but can I use my US playstation to watch a US movie back in Europe? I will use a 220-110 V transformer, but will it work on 50 instead of 60Hz?
As you stated, it will not work on any PAL signal. However, if you are using All US spec components, and you have the correct power converter, then you will be able to use the TV as a "Monitor" of sorts.
