When I got hereThe fuse in the plug is primarily there to protect the power cable from melting & bursting into flames if you try to draw too much electricity through it (like when you short circuit something). It does not really protect (or affect) the electronics at the other end. Nor will it protect you from electric shocks. You put the lowest rated fuse into a plug which does not quickly blow. 13 amp fuses are for heaters, kettles, hair dryers and the like. Try a 3 amp in your monitor power lead, if it blows (it shouldn't) put in a 5. I cannot believe that this is your problem.
I had to change a lot of plugs and it may be that I put in a fuse with too
high a rating, but I wonder if anybody knows what the correct fuse should be
for the Lacie monitor? I think I have a 13 amp which may be causing the
problems. All the other computer stuff seems to be working well with 5 or
even 3 amp fuses, but I was told that the monitor required more power.
I guess, either you have so many bits running off a socket that you are getting a voltage drop, or the area of the room you are in has some electrical interference either from your/next doors wiring or something close is generating an electromagnetic field.
Try
Plug your monitor lead directly into a wall socket, if it still does it,
Switch off all your periferals,
switch off everything in the room except the computer,
then switch off everything in the house,
if you can run an extra monitor on the imac, try that with the main computer switched off,
then run a power lead from a different ring main, normally different floors in a building have separate ring mains,
then move the computer to a physically different place
then have a word with next door and see if they have fitted some heavy duty appliance cable to your party wall
then either buy a voltage tester or get an electrician to check you are getting 220/240 volts
finally chuck you monitor (optional).
My brother rearranged his desk at work and moved a monitor six inches to the left, it refused to work, after lots and lots of tests he discovered that the locked cupboard near his desk contained the electrical feed for the entire University. 6 inches would appear to be a long way in an electromagnetic field.
