I've been using an iMac for the last three years so it's been some time since I've been in the business of shopping for a monitor. I realise that complaints on the internet are anecdotal, but there sure seem to be a lot of them on issues relating to quality control. I'm quite unimpressed that LG offers only a one year warranty, at least on the monitors that I've looked at. BenQ offers three years, but despite glowing reviews there are clearly issues with the one that I'm interested in, the 4K, 27" SW271. For US$1,000, I expect better control over what goes out the factory door. I'm really not interested in spending my life shipping a monitor back and forth for repair. I'm rapidly coming to the conclusion that I should just purchase an Eizo and be done with it. Their 4K ColorEdge monitors are outside my budget, but the FlexScan line, while not inexpensive, includes a fairly new 27" 4K monitor (EV2785) that is about $200 more than the BenQ. Eizo released a companion 32" (EV3285) in August, but it is beyond what I'm prepared to spend. Eizo monitors come with a five year warranty and are extremely well built. The FlexScan color space does not cover the whole of Adobe RGB (it's sRGB), but given that I no longer print color images, and looking at the alternatives, I'm 80% there. If I decide that I do want the larger color space, their ColorEdge CS2730 (2560x1440) will do it for the same money.
