If you can get another Atari to try, it would be useful. If the picture is fine with the other Atari on both monitors, it is likely to be the ST PSU or video hardware putting the noise into the signal. If it is still present on the other ST and monitors, then there could be environmental noise in your area at a frequency that the Atari gear is not immune to.
