LOW Emission Monitor for sensitive human???

zapp22 · 11 Jul 2012

I have a client who is sensitive to EMI. This is a controversial health topic but there are good medical studies that show a certain percentage of controlled samples do display adverse reaction to various forms and levels of Electromagnetic fields, radiation, presence. For whatever reason, this person believes that monitors and wifi are big offenders.... this may be true for all I know. I'm trying to get fast smart on the subject matter.
I do know from high security work that in the past spooks figured out ways to gain a certain amount of data from Displays simply by monitoring the radiation IIRC

any help? And, am I wrong in thinking that old CRT types MUST have had much higher excess leakage than do modern low-power units?

and couldn't it be that the monitors refresh rate, brightness/contrast and perhaps even color settings have more effect on a sensitive brain than does emissivity of other kinds?

Yes, CRT monitors were big offenders, but LCD are not. If this person prefers a wired connection to a wireless, then that shouldn't be any trouble. Otherwise, keep the computer out of his way and he should be fine. The refresh rate and timing of the monitor is a completely different subject, but perhaps he is confusing the two. An answer for the 'perfect' monitor for such a person would have to be tested on the person (i.e. going to a store and viewing working monitors and comparing the affects they have on him).

a low-power monitor is a very good idea, and any 'emissivity' is so low that it won't even reach the person more than 8 inches away from it.

hmm... doing searches for "low power" monitor didn't turn up much. I guess they all think they're low-power these days.

accidentally/coincidentally I just ordered a little notebook and while doing some reading on it I came across an owner review in which he mentioned his sensitivity to "flicker", and a comment on how some people are extremely bothered by monitor flicker. in that case, he thought the flicker was most annoying at low brightness levels [power saving] and not very noticable with the brights on. more homework to be done.

Yes sir. In california, most, if not all monitors are required to have energy savings, called energy star. But this might be a nationwide thing. low flicker might come from a high response time (low number like 5ms). CRT monitors suffered flicker, but unless you get a very poor quality monitor, flicker shouldn't be too much a problem anymore.

Like I said, the best test would be one the person performed himself (by going in and checking them out. He doesn't have to buy them there though, the internet might pull better deals)
