I have found that LCD monitors also make me more sensitive to florescent lighting. If I use CRT monitors during the day, I do not notice any florescent lighting. However, if I use an LCD monitor, I notice the florescent lighting found in stores, at work, etc. Note that besides the AC->DC transformer that you often see as part of the power cord, LCD monitors also contain inside the monitor itself a DC->AC inverter (!), because the florescent backlight requires AC power to function. So you've got two transformations taking place -- AC->DC, then DC->AC! I'm hoping that future technology will lessen these concerns -- there do exist computer monitors which use light emitting diodes for the backlight and also as the main source of light ("OLED"), but so far I don't believe there is anything that is commercially available for a reasonable price. And of course, I don't know if light emitting diodes will be an improvement over florescent lighting or not. Marc |

I have now found, that for electrosensitive people, the GS units should be
less than 30 in stead of the 50, Stetzer advises.

I'm using a trifield meter and looking at readings on magnetic, electric and microwave. I get absolutely no readings on anything next to the monitor. Only on the transformer on the plug wire do I get high readings and I try to keep it as far away from me as possible. I took readings on monitors at CompUSA and when I would put the meter on the magnectic scale I would get high readings on certain parts of the monitor and background reading levels on other parts of the monitors. The store had high background readings. When I saw that this monitor gave me zero magnetic readings on the monitor itself I bought two of them cause who knows if I'd find another like it. My trifield must not pick up the electric readings and high frequencies you mention. I bought this particular monitor at Home Depot as they were on sale this weekend. They ran out in two days. --- In [hidden email], Marc Martin <marc@u...> wrote: > > > Did you also take electric field readings?
