Have a couple of people in my office who use due screens. Don't have any more issues with them than single screens, as long as set up correctly height wise etc.

I have used dual screens for just over a year and we have been installing them on our site (800 people) for about 2 years (only to those people who request them). I have had no problems with the screens nor have I had any complaints. Are you imposing this change? It could be that people don’t like this change. Were they consulted? Perhaps it is being seen as a way to get twice as much work out of people (daft I know but people can get hung up on this sort of thing) and that a dislike of change could be a contributing factor to the headaches. Are the new screens similar to the existing ones or are the very different (smaller less clear etc) this might be a contributing factor. Do all of the people complaining have similar symptoms or is there a range of symptoms? Those are my thoughts so far

I am due to visit a site this week where some staff use 8 screens wrapped around them. I do recall some tinkering to the ambient lighting after headache complaints and I know exposure time is limited (when there's sufficient staff to circulate). I will make some enquiries.

Dual screen use shouldn’t have to much of an impact to the users. When supplying new equipment or a change to the users set up. Display Screen Equipment (DSE) assessments should be undertaken. Training should be given were necessary to the new equipment. Things to consider: Ensure the fonts are the same on each screen, this should help stop eye strain. Eye strain is a common problem to users of DSE which results in users having headaches. Ensure users take regular breaks Ensure the DSE assessments have taken into account environmental issues eg. Lighting. Having a glare can also result with users straining their eyes. Speak to the employees reporting the issue. There maybe another outlining issue which is resulting with them having headaches, stress shouldn’t be ruled out.

I'm mostly going to say the same as everyone else - most of our CAD people have been using dual screens for three or four years, within the last year almost all our engineers have moved to dual screens and we've had no complaints or problems. Personally, I work with three on my desk, but one is a smallish one just glanced at for reference occasionally. The key issue, however, is that no-one has had dual screens imposed - everyone was offered dual screens, about 10% expressed a preference for a single larger screen instead (most got that preference), and about 10% just wanted to stick with what they had (everyone got that). Several of those have changed their mind since, but no-one had two screens imposed on them. It's often change that they don't control that upsets people more than whatever the change is actually to, I think.

We use dual screens in my place of work and have had no complaints thus far. Rules to remember, take time away from the screens hourly even if its just going for a five minute wander to give eyes a rest. Carry out DSE Risk Assessment and if required have them go for an eye test. My wife only uses one screen at work and she constantly tells me she has a headache at night !

Bob, you are right - 8 screens is an absolutely mad way to do business. How anyone can process so much simultaneous information is beyond me. It would give me a headache within 45 seconds. However, this occupier is a city trading financial commodity type hedge brokers (as you can see, I don't understand any of it!?) and apparently, they all work like this. Thankfully, I am only there for fire safety reasons

Dual screens are the future. I've had them for the past 6 months and could never go back to just one. Your users just need to get used to them and find their own way of working with them.

I've been using dual screens now for 3 or 4 years and would not swap back. I'd have 3 if I could. I write reports and need to do research via company servers and internet. Word open on one screen, web browser on the other - nice and simple. In the old days, everyone wanted a larger desk. Dual screens gives you more desktop space to play with. As Seabee says, it's the future.
