Question about Computers & Internet
Are they both about the same age? Also have you recently added a device that is sitting near the monitors such a an external hard drive, printer, new speakers or power cord or cable next to or against the monitor cable? I sounds like EMI to me, shield the cable or plug of the offending devices into another outlet away from the monitors to test that theory, or having them on a separate surge protector should eliminate the noise you are reporting. Some go as far as adding UPS with line filtering (or conditioning) for the devices - you see it with home theater setups when the TV, computer, games and stereo are all plugged in the same outlets on the same home circuit.
