When I tried to contact them about the *tons* of software issues I had with the flat version of this, they told me they had no stock and couldn't send me a replacement. I had to return it to CCL. No offer of a firmware update or anything like that. And it's a shame there's no way to do a user firmware update. The glitching, crashing and other issues put me right off what was previously a flawless brand for me.
Most reputable e-tailers have already done the firmware update at this point. I think you'd have to be very unlucky to get one that requires an update. But you're correct. If it needs a firmware updating after arrival,you need to send it to a repair centre. iiyama do cover the cost of shipping both ways though. (y)
iiyama is still a good brand, currently I'm sat infront of a iiyama Prolite X3272UHS 4K screen, that I've had for a few years without any problems - and yes back in the day they produced some of the best CRT monitors with Sony Trinitron tubes you could buy.
You have to sent it to repair centre to have a firmware upgrade
Already mentioned but i'll reitirate that they were a household name when it came to monitors of the CRT variety and widely repsected for a quality product in the era of Y2K. Not sure what their LCD stuff is like but they are a reputable Japanese firm and their most recent monitors have received good reviews overall. That said I think the quality control on some of the latest models got some bad press but issues were fixed with firmware updates. As with anything it's worth doing a bit of research but they aren't a company to avoid imo.
