Hi There is no guidance on this yet- not from the HSE who seem still to be getting their heads around flat screen monitors. I suppose it has to be decided on a case by case basis with the key question being what the screens are being used for. My own modest two screens set up does not cause me any problems as I use one screen as the master screen and one as the reference screen( effectively replacing the document in a document holder that I used to be referring to) What else people use them for I don’t know; I can’t see anyone looking at more that one screen at a time, while typing for example. If they are being used in hospital to monitor patients for example then that’s different from sitting at a desk typing in information. We have quite few such set ups on our site and not had any reports of problems (and our staff DO report problems) The main issue with DSE is not he workstation set up but simply people trying to do too much work in too sort a time and neglecting to take breaks (either because their bosses set impossible schedules or because they themselves choose to work that way).

No issue at all with multiple monitors, use them myself. What there is a lack of is guidance and standards for such setups and the particular problem I have with 3 x 22" widescreen monitors side by side on a straight desk meaning significant upper body especially neck movement to be able to look at them. I want a curved desk so that turning on the chair will mean the body can be placed square in front of each monitor, but there is no guidance etc to support me on this.

That was easy wasn't it - you identified a hazard and a suitable control measure. No need for published guidance on something so simple to 'assess' from just looking at the set-up. IMO of course.
