I'm not sure about if it should go here, but I have had a couple of migraines recently, could it be anything to do with the monitor? I do spend quite a lot of time on the computer after all.
It's a 19inch in size, and I think I'm running it at 75Hz?

First question - do you wear glasses?

Interesting thread. I am near sighted and I cannot read a document on paper at 20 inches without using my bifocal glasses. But I cannot use my screen at 20 inches WITH glasses. Must be the clarity or font size. Some GIF images irritate my eyes so I scroll them out of the screen to read the post. I don't get eye strain headaches, however, if I use backlighting so as the screen is not the brightest thing in the room.

Most of the time I don't need glasses, but my "Vari-Focal" spectacles are handy for protecting my eyes, and makes all round vision when driving, slightly clearer....
My long range vision is fine, but as I get older my close-up vision (reading, etc) is getting difficult.
During my recent eye test I told the Optician that I was having problems with with my close-up vision from 9 Inches, (book reading), to 2 Feet distance...(the Computer Monitor Screen), so they modified a pair of Vari-Focal Lenses to gradually magnify an area in the centre and bottom of the lenses when looking down at objects, and looking at the Computer screen from a sitting position....
...they work perfectly...!
"Vari-Focal" Lenses provide a gradual transition in clarity depending what part of the lens you look through...
Bi-Focals only provide two areas..long range, and short range.

I think Folks who regularly suffer from "Migraine" will suffer from headaches for whatever reason...they are generally stuck with it!...

Paul...a Pint Glass for me...please... ;)...!

I've had Varifocal lenses in my specs for a long time. They took a bit of getting used to when I first tried them but I'm quite happy with them now. I don't think they're ideal for using with a computer as I have to hold my head up to look at the monitor. I have the same problem with the bottom shelves in supermarkets.

I used to suffer terribly with migraines. Came on all of a sudden when I was in my early 30s. Scared the living daylights out of me. Nothing to do with my eyesight or computers, although staring at a monitor for hours on end can't be good for you. It's more likely caused by diet, too much cheese, chocolate, coffee - that sort of thing. Fortunately I grew out of it just as the 'experts' said I would. I occasionally get the zigzag visual effects but haven't had one of those blinding headaches for years.

One of my lovely Daughters-in-Law suffers from Migraine, but knowing her as I do, I think most of it is caused by stress and worry, often in her Managerial job, etc...
(...whether my lovely Son has anything to do with her stress...I don't know... ::)... ;D....!

Paul.... ;)...!

Doug...does you regular; "lying down in a darkened room" help?... ::).... ;D...!

I was forgetting stress which I suspect can be a big factor. I used to get migraines mainly at weekends which I put down to a temporary relief from the stress of work. This had the effect of ruining my weekend. I'm sure there must be a medical term for it.

Sometimes it was the only option. Fortunately I no longer suffer from it.

Wearing my glasses seem to help, probably a combination of tiredness as well I guess.
Thanks all.  :)

I never needed glasses, but I occasionally had migraines when working hard at the computer for too long... I know for a fact that CRT monitors give me headaches if set to 60hz... I can see the flicker and it bothers me to no end... setting it up to 75-80hz solves that though...

Also, I have always left the gamma/brightness settings low enough so that the screen isn't, as Steve M said it, the brightest thing in the room. Too bright a screen is a bother to me, and I try to set it to a brightness akin to that of a sheet of paper under room lighting (not as easy at it seems). Also, I never use the pc without a light on.

Cheers

If it's recently... do you get a new chair? I used to get headaches until I realized they started in the back of my head and I related it to the chair I was using... caused me to sit incorrectly because I had the chair too high.

75Hz should be just fine. 60Hz should be ok too. Do you have florescent lighting? I remember reading about a study where the lighting caused visual problems.
