Time for a history lesson.
Iiyama used to be one of the best CRT monitor makers a decade ago. I remember in 1998, when I wanted the best 15" crt that money could buy (Sony). I couldnt justify the £222 expense, so I plumped for the 2nd best 15" CRT at the time - Iiyama - priced at around £180. I was very happy with this unit and it was miles better than the generic displays found in offices/homes at the time.
A few years later, Mitsibushi emerged as a great CRT monitor maker. They had one of the best 21" CRT monitors around. They were going toe-to-toe with Sony, but this was the time that Iiyama gradually began to go backwards. Iiyama seemed to be concentrating a lot on the budget market now, leaving Sony and Mitsubishi to fight for the premium segment.
Soon after, TFT monitors started to go mainstream and at first Iiyama seemed to be holding their own, but gradually found themselves struggling to keep pace with their main competitors - Sony (as normal) and the emergence of Dell. Eventually, over the years, I have noticed that Iiyama have almost vanished and become a bit part player in world of PC monitors. Dell are still holding their own and Samsung really seem to be selling a lot of their panels, either under their own brand name or via 3rd party manufacturers.
10 yrs ago, if you wanted a monitor and had money, the top of your shortlist would have the names, Sony and Iiyama on it. In 2007, if you have money to spend on a monitor, Iiyama is not the name you would reserve on your shortlist. Dell, Samsung and even Benq have overtaken Iiyama in terms of reputation.
As for the PLE2201W-B1, I have no idea.
