Basic elctronics tel me, that when a electro-magnetic storm can have an
impact large enough to overload a power station, it wil influence your
monitor aswel.

My sony tv is mounted on an rotating platform, so I can view television
whereever I sit in my living-room. When I rotate too fast, I get a funny
coloured didtortion at the corners. And that's just the influence from the
earth magnetic field.


Your impression is incorrect. The Earth's magnetic field is far too
weak to signficantly affect a TV monitor. A magnetic storm does not
directly affect a power station. What such a storm does is induce DC
electrical currents in the hundreds and hundreds of miles of
transmission lines in the northern regions of the Earth where the
field strength variations are significant. This can produce power
surges which the distribution network may be unable to handle.

They do make TV's (larger screens) with minor pincushioning adjustment switches for north and
southern latitudes. So, from that info, I'd say the earths magnetic field does affect TV monitors.
Now a CME is another thing alltogether.
