If you're light-sensitive, reducing the brightness might help.  But
reducing the brightness just alters how much light the LCD
panel lets through.

I think there are two reasons why you find this helpful: less fluoresced light reaches your eye; and the frequency of the fluorescing light source is changed.

CCFL backlighting is designed to trick the eye into seeing it dim in brightness by adjusting the speed of its off-and-on cycling. Lower brightness is obtained by keeping it off proportionately longer. (Typical cycle values are 100-300 Hz.)

The citation supporting this on Wikipedia is a glossary definition of burst dimming on an electronics company web site: http://www.maxim-ic.com/glossary/definitions.mvp/term/burst-dimming/gpk/998

If you wish to better understand how brightness and contrast are related, then see articles in Wikipedia on 'Liquid crystal display' and 'Burst dimming'.

Reducing the backlight brightness for LED
monitors actually increases EMF, because
the LEDs are dimmed by pulsing their power.

Ok brightness will have no effect on emf then. Darn it. Can't find the backlight. Loni

Unless the manufacturer of your set is implementing the backlight
adjustment via the brightness control.  I'm just aware of manufacturers
doing that... (?)

Isn't that what is done for florescent backlighting
as well?  I don't really care what it does to the
meter readings, as it obviously increases my
tolerance for TVs and monitors by dimming
the florescent backlight.

I did a search to see if anyone had covered this before, and found Jaime's post. You can use a camera to figure out your LCD's PWM frequency: http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm (See "Testing and Interpretation.")

If you don't mind pulling the LCD open and soldering stuff, you could soften those pulses with a capacitor. I'll probably end up doing that for my own computer.

Well no, there are many flicker free LED monitors on the market these days, I'm using one right now.  :-)

Most everything from BenQ is flicker free.

I haven't had very good luck with me Acer/BenQ monitor, but maybe that's because it has an internal power supply...

My BenQ 28" LED monitor has been the best monitor I've tried in over a decade... and it's a current model!

Re: Do not buy LCD Monitor and LCD TV.

There are monitors and monitors.
What disyturbs ES persons is the fact of *dirty air*, which only a few persons can measure.
These are frequencies between 5kHz and 10-30MHz.

I had an Acer 26"monitor, wich showed a large peak at 4,5MHz.
Now I have a Philips 27" 273E-LH which is fine.

Normally LED is not so good, because it radiates special waves directly frontwise.
These waves go even through wood, etc.
OLED does not have these effects, but are only available as large TV.

@Kathy,

no, the jerry's prefer to write in German.

But there is Google translate and there is Babylon and other translate programs.

On that website there are a lot of very interesting studies.

A lot of phenomenas, where there is no reasonable explanations, can be explained  with *longitudinal waves*.
See: http://www.milieuziektes.nl/Pagina600.html
Yes, there are also a number of German documents.
A lot of strange elektrosmog phenoma can easily be explained that way.

I am working a lot with Non Linear diagnostic Systems.
Placing a headphone on the head of a person, I can scan and treat a person.
(This is ideal for finding and treating the underlying roots and origins of electrosensitivity.)
Now, with the use of longitudinal waves, I can scan and treat at a distance.

My wife, sitting in the bedroom asks me to lokk at her left knee, where she has pain at the moment.
I scan and treat her on my desk, and suddenly she calls me, that the pains is gone.
Tonight I scanned and treated my granddaughter, who is on holiday in Israel (some 3300 km away).
Next week I'll expect a report by her when she is back.

We found that digital TVs gave high dirty electricity so we bought a 12 volt TV which has a 240 volt adapter.  The largest one we could get was 80 cm (from memory).  It is an AXIS and they are made for boats.

I know what you mean about CLFs, we recently moved to a house and noticed dirty electricity of about 2000, removed them and it went down to about 15.  Better sleep too.
