Can the flicker be 'measured',strobed or videoed in some way so that I can avoid the 'Headache Test'and persuade the non seers to FIX IT?

I am the proud new owner of a 46 inch lcd1080 as I acquiessed to my husband during a mental lapse. I now have the behemoth stinking up the family room and want to know how long it will take to outgas with the windows open, and if the danger passes once it outgasses. Please answer as I am nervous, I have a child.Thanks.

Try switching from the VGA cord and using the DVI cord instead. Worked for me.

I found a similar problem that caused me to become nauseated and dizzy. But instead of the cause being the monitor, I found it was the air contained inside of the computer being outputted by the fans in the back of the computer. When I better vented the room, added a top notch air cleaner and set my power settings such that the computer would effectively turn off after 15 minutes on non-use, my symptoms have largely dissappeared. After later using a laptop computer in a different and well vented room, I found most all my systems disappeared.

Although a number of people have suggested the problem relates to the monitor, I'm convinced that in many cases it's the chemicals and heavy metals that are used to manufacture the boards and contained within the computer (e.g., mercury, leaded plastics, pcbs, solder, to name just a few of the many hundreds) that are causing the problem. I imagine if the federal government tested the output from the back of the computer being pumped out by the cooling fans they'd find that many toxins are being outputted into your living or working spaces. It's funny that computers must be carefully disposed of due to the many toxins contained in them, but it's okay to use them in the house and working spaces even though they're heated up to relatively high temperatures (releasing at least some of the toxins into the air) and then cooled by fans that pump these toxins and heavy metals out into your local environment.

I'd be very interested to know whether any objective organization has ever checked this out?

On Friday I started to use my new LG LCD monitor. There was a smell like someone was smoking something in the room, but no one could. Later that night I became ill. Saturday early morning I was taken to the ER, I have not been that ill in many years. After 3 hours I was released, and the Flu was suggested.

Sunday morning I turned on the computer and sometime later I went back into my computer room
& bedroom. The fumes hit me quickly. I immediately became ill, nausea, dizzy and felt very ill again. So I immediately turned off the monitor, opened doors and windows and stayed on the living room couch. I began to feel better and recovered quickly.

I am now looking for a testing facility to find out what I was exposed to, and then find out if any long term effects are known.

Beware of new monitors. If it smels, gives you a headache or anything peculiar STOP USING IT!
My medical bills will easily be more than 10 LCD monitors.

I put my system into standby today. When I came back 4 hours later it didn't turn on with mouse or keyboard input. So I rebooted it. The icons had all lined up on the left and they had a flicker (although the desktop background did not). In other programs, information in the window is fine, but the border and menus flicker. I suppose it is more of a regular flash once every 5 seconds or so.

No settings have changed. Refresh rate is 85hz.

Any ideas would be appreciated. Thanks

FreekLord, I think the problem is the font size. To change the font size go to display->appearance->advanced. Now click on the bar tha comes down and is called Item (it will be set to desktop). Then go to icon, now you can change font, font size and icon size. I use Tahoma. Icon size 31 and font size 8. This may also help tawania, if not, there are many other options in what I just explained that will because I have had both of these problems.

A new Sony LCD tv - 26 inch seems to run quite a bit hotter than a tube tv. --- it even has a fan and hot plastic (subtle) can be detected in front.Are LCDs known for more toxic outgassing? Does it lessen, and is it a concern - worth going to a different type of tv. I seem to get a headache from it- but it was expensive.

thanks,.

Michael

I have a dell 23" lcd tv I am using this as a computer monitor. I have a fuzzy pink edge all around the screen about an inch wide and the screen flickers (like a low refresh rate) I am connected with a dvi and I understand the screen should not flicker. Is the lcd bad? its about 2 years old

Ok, I read the article, did the procedure recommended. But I think mine is of a different category. The msn dialog box (when chatting to someone) has the flicker and moving issues (No other program has the issue.) sometimes just parts of the box "jumps" back and forth. Sometimes it is when there is a emoticon or wink that makes all the box on the left Jump or move. i am running xp home with sp2 if that helps. Thanks for any advice!

As you can see from below testimonials, some LCDs are worse than CRTs
and
some CRTs are worse than LCDs

And all sorts of "expert" solutions (ranging the full gamut) fail - due to the problem with outgassing of flame-retardans/epoxy chemicals (& maybe more). It's all unregulated.
btw: you should also read the online PDF book Black On White, by Granlund-Lind which includes testimonials by many Swedish professionals such as engineers & CAD designers.
Anyway, here's the testimonials URL:

Depending on the buzzing, that may not be good. Your monitor may have a hardware problem. Unfortunately repairs are oiften more costly than simply replacing it.

Before you junk it, I would: turn it off for a few hours (if it's been on continuously), and if it has a "degauss" button, try pressing that while it's on.

I recently had my computer reformatted and have installed the same programs as before. My screen fonts however are so faded and almost broken looking i cannot see type and its painful on the eyes. I went into properties/appearance/effects and chose the "clear type" option as opposed to the standard option for smoothing type edges and all of the font now has green and red shadow lines around it which is even more painful on the eyes. My monitor is an LCD.

Most LCD screens, such as on a laptop, do not allow you to change the refresh rate. (The whole "refresh rate" concept doesn't apply to a LCD connected via a digital interface.)

There are magnification tools that come with WIndows ... I'd check add/remove windows components in the control panel to see if they've been installed.

I'd also check the overall DPI setting windows runs at as described in this article: http://ask-leo.com/how_can_i_make_the_text_on_my_screen_larger.html By changing it you should be able to magnify everything.

There are also windows themes in the Screen control panel that may choose larger fonts and color schemes that might also be helpful.

Dear Leo
We are suffering from Cancer. Ann had breast cancer. I myself have had head-cancer, in my head. When we rent books from the local library we get them out of the large print division, which makes it a lot easier to read. Do you have anything like this available for my DELL computer ?
Thanking you, John Meskers Sr
