The Z27x's leanings are apparent in its "workmanlike" build quality that PC Advisor calls "among the best on the market." PC Mag notes it has plenty of connectivity with its bevy of USB ports, though AnandTech finds the choices of an HDMI 1.4a port or dual DisplayPort 1.2 inputs rather "limited." Tom's Guide also feels that users in bright workspaces might want to purchase a hood, thanks to the "light density" of the anti-glare layer.
Those limitations are relatively minor considering the quality of the screen itself, which offers virtually "perfect" sRGB numbers and RGB balances according to AnandTech, finding color errors "practically non-existent." Tom's Hardware concurs, calling inaccuracies "completely invisible" and colors "perfect to the naked eye." They also call the maximum black level "quite respectable," and while AnandTech notes it's "not as dark as an IPS panel can be ... most of its target users should be fine with what it achieves." AnandTech did have some issues with the z27's uniformity, but PC Advisor found it "cleanly viewable from all angles."
If color accuracy is what you desire, then you can't do much better than the z27, especially for the price. As Tom's Guide says, "nothing else even comes close for less than five figures."
