I have in my company, several people asking for help with swimming in their monitors. There systems are connected to a half wall (windows on top, power and heat on the bottom). The head is steam radiation via baseboard radiators. These monitors are NOT next to any known magnetic fields. I have verified that if the monitors are physically moved away from the wall/heater the noise diminishes. In the row of multiple cubicles only selective people have the problem (perhaps 3 out of 15 or so). The noise appears to be 60 Hz in nature although no color purity problems were noted.
I'm assuming that I am now looking for magnetic fields, possibly from the electrical feed line, or could it be the radiators? Is it possible for these to be nodal or selective along a common wall? Has anyone else had similar problems? Would it make sense to obtain a meter to measure the magnetics? Any suggestions appreciated.
