Do not buy LCD Monitor and LCD TV.

> Okay, I don't know how to answer your question.

It should be simple -- do you have a Sony, Panasonic, LG, Samsung, etc?

And what screen size?  32", 37", 42", etc?

Interesting this discussion lcd vs led tv, although also on this we seem to react different...

Best way is to test as much tv's as possible?

In Belgium/Europe I know 1 web-based-company where you can return your purchases such as tv's and return no questions asked,

In the past I returned 2 projectors that way. By the way these projectors must've been the worst emf sources I've ever known (although I had read good things about projectors here),

Projectors are also awful in the amount of "bad air" they produce: a lot of positive instead of negative ions!

For me these projectors were much much worse than the plasma tv I sold and didn't have that much problems with. Still emf-wise plasma must be very bad, having read a lot of bad stuff about it here! I did feel it in the house when the plasma tv was off but still in the electric socket (which seems a bit similar as Puk's problem with neighbour: plasma probably causing a lot of dirty electricity on the net).

Bill, Donna replied to me that she was using a 23" Samsung LED monitor.
So I'd guess it's something like this model:

Oh wow, that's a good recommendation. I'll look in to that!  Thanks again. Loni

Many LCD TVs and computer monitors have adjustable backlights. I have found
that my symptoms diminish greatly if I simply turn down the backlight
to as dim as I can get away with. Especially when viewing at night,
there is no reason to have the backlight set high.

That monitor has an external power supply.
Donna, if possible, please tell us the voltage
and current labeled on the power supply (DC adapter).
If a compatible linear supply is available
this sounds like a a very promising monitor!

The big point with LCD/LED monitors and TV's is the *dirty air* they emit.

I checked an Acer LCD 26" monitor for VLF (5 kHz - 150 kHz), which was all right.
But at home, I found big wide peaks at 4500 kHz, or 4.5 MHz.

So, try figuring that out with a HAM radio.

Many people asked me which TV they should buy, but in the shops, they change the types quicker, than I can measure.
And the same TV, which has for instance a H in the typing, and I find all right, may have changed over the weekend into a V in the type number, and is now a very nasty thing.
It has to do with the electrical components they are using, and they are changing all the time.

I have also found, that certain types of stereo instaalations like Harman Kardon, do cause a lot of *dirty air* and also *dirty power*, which goed to a nearby TV, which emits it as *dirty air*, even 5 meters away.

I don't know if this is what you mean, but I find that using a large egg shaped himalayan(sp) salt crystal lamp beside the computer monitor makes a big difference.  The salt releases negative ions when it heats up.  There's a small nightlight sized incandescent bulb inside it.  Lots of people report being energized by the negative ions and some say it helps reduce EMF, though I don't see how.  All I know is it helps me.  It seems to make the air surrounding it fresher and less heavy.  Works great as a nightlight on the side farthest from my kids beds in their room too.  It does plug in, so it might actually be worse for some.  But for me I feel it most when sitting within 2 feet or so from it and it makes the computer feel better to me, especially for my facial heating, burning symptoms.  I have an LCD only 20 inch monitor and with the backlight set to 50% I can use the computer for about 30 minute intervals throughout the day without severe discomfort.

Do you mean, how do you adjust the brightness of the backlight?

Usually it is with your TV or computer monitors remote control
or adjustment buttons.  Usually there are various menus, and
backlight is often found in the video/picture adjustments,
along with brightness, contrast, color saturation.

Note that "Brightness" is NOT what you want to adjust --
however either "Backlight" or "Energy Savings Modes"
will work.

Marc

I don't have a remote for the computer monitor. I'll try to figure out for the tv. thanks Marc.

Tv is adjusted so we'll see how that works. I don't have a clue how to access on the computer monitor?  Any ideas. control panel?

Usually there are buttons on computer monitors that put you into
an oncreen menu, and then you can search for the backlight setting
in the menus using those buttons.

Marc

Ok Great I found it & it is to 25 instead of like 75 so we'll see how that works. Anything need to be done about contrast?  Thanks so much Marc! You are the Bomb!  Loni

Turning down the backlight is the thing that help ES symptoms (well,
for me at least).  You are free to turn UP the brightness or
contrast if the backlight is making things too dark, as I don't
think brightness or contrast will have any impact on ES.

Backlight turns down the brightness of the florescent lights behind
the LCD panel.  Brightness and Contrast control the LCD panel itself.

Marc

I just purchased a Bush 19inch LED TV that runs on 12volts so I got myself  
a Numax deep cycle leisure battery and a good 12 volt regulator pack and
hey  presto I am watching digital TV in my log cabin, this TV can also be used
as a  VDU when attached to the pc or laptop, this ofers me some renewed
hope and will  hopefully help my tired eyes from veiwing the laptop 6ft away
(albeit on  zoomtect)

Hey Paul---sounds good!  But I can't find that TV online.
Where did you get it, and do have a model number?

This site has some up to 22", but maybe not LED?

Oh well can't find on the tv nor the monitor where is says backlight. It just has brightness, contrast, so on so forth. Any ideas how to find it?  Loni

It's possible that your TV and monitor don't allow you to adjust the
backlight.  I pretty much make that a requirement for the TVs and
monitors I buy, so they all have this capability.

Marc

Oh well maybe that's the case. This LCD is a 2004 tv so kinda old. The monitor was purchased in 2007. So adjusting brightness does nothing to do the EMF eh? Loni
