I bought an iiyama Vision Master Pro 451 monitor from Scan on the 18th of May 2001. Problems soon developed with the monitor, which included purple discolouration in the corners of the monitor, as well as a blurry image on portions of the screen. I decided to take the matter up with iiyama directly rather than seek a refund as they swap the monitors out for another if a problem occurs. After three swap outs, each 451 developed the same fault after a few months. I spoke to iiyama on the telephone and managed to get a Vision Master pro 454 sent out instead. This pleased me as I figured the 451 was prone to these problems, and a Google search agreed. Back in May 2004 I realised the same was happening to my 454, and instead of contacting them for yet ANOTHER swap out (which would involve me and my ageing father having to lug a huge monitor up an awkward set of winding stairs), I lowered the resolution and this seemed to rectify the problem a bit, if not fully. I realise this was silly as I would've been better off contacting iiyama for another swap out or Scan for a refund, but I was really fed up of having to wait in for another monitor to be brought, bring it up the stairs etc and have the problem occur again in a few months time. Now recently my 454 (which is the fourth swap out in total) has developed the blurring problem again. I have decided to contact the retailer I bought it from (Scan) because I feel I am getting nowhere with iiyama. A quick Google search reveals I am not the only one experiencing these problems with this monitor, although not much information is availible so I decided to post here to see if anyone has had the problems and what was done about it. I have had a look at my invoice and it seems my warranty has ended in May 2004. Do I have any further rights considering the number of problems I have had and swap outs? Indeed would the guarentee be reset when I received a new swap out? I believe I got the 454 in May 2002 but it could have been later. I was hoping that someone in here may have the same monitor in order to see if theirs went the same way and what they did about it. Its a shame really, except for the blurring problems it has been a cracking monitor and I will be sad to replace it with another model, but I doubt I would buy another iiyama monitor after this experience.
