Do you suffer Headaches from LCD screens

When I got a desktop PC with LCD a few years ago it wasn't long before I noticed headaches. Became obvious that every time I used that computer I'd get a headache.

I knew something was wrong so I searched the 'net for answers and found plenty being said about LCD's and fluorescent lights, which my computer room has had for lighting for many years (those compact bulbs). People have associated headaches and mild nausea with offices lit only by fluorescents, I'm just unsure of the facts.

Well, I use a notebook computer mostly anyhow and seldom use the other PC, but all of my lights are fluorescent now and I never (or almost never) get headaches, so I don't know what the answer is. I even wear eyeglasses yet not to read or use computer so I had suspected it was always a bad eyesight problem. I should use eyeglasses for reading, too, but I don't.

Could be that the desktop LCD connects to analog monitor port, not DVI, because I wanted to use it on another older PC occassionally.

The origins of headaches, the exact mechanisms, as well as the structure and function of our nervous system where we sense these, are still largely unknown. We know that various stimulii can trigger headache in some individuals but not in others. So, can a LCD monitor by some yet unknown way trigger headache in some individuals?
We can't rule out the possibility.
I rarely get headache from any stimulus though.

The flicker used to drive me nuts on my old CRT but after going LCD I can use all day with no problems

You'll gain nothing with the extra RAM unless you're a gamer. It's just that most modern cards come with more RAM now.

Regarding graphics interface, don't confuse the ordinary PCI slots in the machine with the dedicated graphics card slot which will be either AGP or PCI-Express. You do need to get the right sort of card!!

3 years old and I'd be guessing at AGP, but you might just have one of the first PCI-E.

OH, and to the nay-sayers concerning the importance of DVI, if it's an AGP card you get (one of the two I suggested), and it doesn't give you a much better image (still can't promise it'll cure the headaches ), I'll buy it back from you as I can always do with a spare dual-DVI card!!

Heath,

My 19" in the office is set to 1024x768 too. Standard 4:3 no WS (Wild Screams?), which I can watch comfortably from 1.2 mtrs (4'). On BBC News a capital letter is 5 mm high.

Frontal headache is most common if it´s eyeproblem. Stress or Whisky has other locations.

Sometimes visuel problems occur with the screen but not with reading. You can be slightly oversighted and/or astigmatic. It´s not sure simple +1,0 helps in that case.

Messy, but I work on lots of different tasks

I was prescribed the glasses for screen work when I sufferred from Migraine level headaches after lots of screen work before I bought the two Dell 24" screens. Didn't get on with them (the glasses), and don't wear them except for reading paperwork now.

You almost certainly have the brightness way too high so it it like staring into a 100 wat lightbulb.

Unfortunately, brightness for LCDs are like megapixels for camera ..... more has gotta be better.

Try turning the brightness down to minimum and making sure the ambient room lighting as close to the brightness of the LCD.

This should help.

But basically I sit in front of two LCD screens. One is on my MacBook, a 17" screen with 1680X1050 resolution. No headaches, ever. Second one is my Formac 20" display, 1600X1200 resolution. No headaches there. i haven't really had a decent headache for nearly 30 years, come to think of it.
Do you also drink coffee? (I stopped that 30 years ago)

If you do or don't drink coffee, but don't wear glasses, could it be that your aging eyes need glasses now?

If I have uploaded an image don't hesitate to de-noise it, correct the WB, clone out dust and dead pixels, saturation, USM, resize, print and send me the result..
Also advice and criticise.

Kind Rgds

It may be possible to change from 60 to 75 or such numbers, or vice versa. Maybe the refresh rate has hit a certain resonance with your brain?

Actually, yest. But it is from the glare. I don't know your age but if you have early cataracts or what is known as dry eye or suffer from migraines, the light array can be a migraine trigger. Really.

I am not a physician and this is not medical advice.(Disclaimer), but has actually been my experience.

Results after medical conclusions??? Turn down contrast on the screen, eyedrops, eyedrops that help create more tears (prescript required) and in my case of severe migraines with light effects as a trigger, Topomax, since Immitrex was not working.

Perhaps more than you asked for but has made a huge difference since I
work behind a computer most of the day.

Good luck.

It is always good to seek a medical and optical exam to rule out other conditions.

Regards,
Linda

Hello! Yes, I agree--I don't think it's in the technical refresh rate stuff-I also replied.

Hope all is well!

Linda

I think I led the rabbit chase down the refresh rate path. It seems it has little effect on LCD monitors and massive effects on standard CRT monitors.

Sorry! Just trying to be helpful while knowing just enough to be dangerous!
