I get a horrible headache. So I have to switch it off.
My problem is that I am one of those energy sensitive persons that can't use cell phones. I have a brand new system sitting there that I can't use. Together with a nice 23 inch display.
Dirk, The most common causes of this type of problem are: - visual - different screens do different things to different people. A good ophthalmic optician (not just someone who tests eyesight, but a professional eye specialist) will be able to advise and may well be able to suggest solutions - auditory - some computers emit high frequency noise that can give some users headaches. An easy test is to wear closed headphones - stress. There are also many causes of headache that can be triggered by computer use. A neurologist will be able to work through those possibilities. Radio frequency emissions from computers are much too weak to have any biological effect. To the best of my knowledge, no-one has ever shown that such low levels of non-ionising radiation have ever generated this sort of effect. I am not saying that I do not believe you, just that if it is true, I think that you will be unique, so of enormous interest to doctors. Although headaches are very common, recurrent or persistent headaches can be medically important and you should see your doctor if you suffer from them. Howard.
