My supervga monitor seems quite sensitive to RF noise. An electric fan in another room, and even FPU activity in the system unit next to it (which uses a Cyrix 8D387, which goes into sleep mode when not in use), produces small but noticable bits of noise and distortion on the screen. I'm a software guy, and more or less a hardware idiot, so I'm not sure what I can do about this (or even if it really is an RF problem). I see that there is some kind of filter or ferrite core or something on the monitor's video-in cable; can I beef that up somehow? What parts do I need, and what do I do with them? Would it help to put some kind of filter on the monitor's power cable as well? (it is already powered through a power bar that is supposed to do some slight filtering) Any information will be greatly appreciated.
