For several months PCAdvisor put the Fujitsu Siemens 20 inch model 5100FA as top dog monitor (out of ten models). There is no 5100,... should have been 5110FA, now corrected, but revues elsewhere equally praised it, particularly the 600:1 contrast ratio. I didn't buy because traders like Dabs, Simply Computers... put me off with their dead pixel disclaimers. Then I discovered the ISO Spec 13460-2, which seems to give top quality pixel priority to the military and medical users,-nowhere could I find class 1 5110FA monitor.
A few weeks later I saw the Iiyama AU5131DTBK appeared to have the same work engine as the F/S 5110FA, - just look at the specs. It also has USB2 outlets instead of the (I think) limited 1W speakers, and it has screen pivot, inc s/w.
I speculated Iiyama sourced from Fitsumi, would be selective in the screens, and also saw they give a 3 year on-site swap. The spec included the same 70 000 hr cold cathode tube life (6 tubes). Now I've got it I am delighted, and haven't seen a dud pixel.
I notice Iiyama have a 19inch 1600x1200, with pivot, at about 800ukp inc vat -and I was tempted to buy at a third less cost. Two things put me off. (i) The specs were down on the 20 inch, (ii) I remembered a comment/opinon that the 20inch was in quality and size good enough to watch DVD/TV.
