OK I'll get an EE to help me out. Did you ever used that with a monitor? is
the 60 Hz vs 50 Hz a problem?
When I went to the US recently, I built my own 110/220V
converter. I
found a small (10VA) transformer that had dual 120V primaries and wired
these as an autotransformer. Boxed it up in small wooden box and Bob's
your uncle.
PS If you can't work out how to do it from the above, don't try it
yourself, get someone with some more electrical knowledge :-)
