Summary: Bought this as a second monitor to match a 21.5'' All-in-One Computer of a Certain Brand That Is Named After a Fruit -- glossy finish and all -- and it fits that bill great, but I have not been able to perfectly match the colors side-by-side after quite a bit of tinkering and some rudimentary calibration. It's more of an annoyance than an issue since there's probably much higher-end equipment, in software and hardware, to achieve a perfect match.
Summary: Bought this to create a dual monitor setup. Unfortunately if you set the resolution off recommended the picture is horrible. Doesn't function well if trying to setup with two different monitors (laptop, older monitor). When setup on recommended the picture is fantastic. Just gave in an bought a second of the same. Functions great in that configuration or as a single. Overall great monitor, for the right setup.
Summary: excellent monitor. Color was nearly perfect out of the box, and only needed minor tweaking. The controls for doing this are poorly located and not intuitive, so it takes a bit longer to adjust, but then the OSD times out, so it's back to square one. Yes, I adjusted the OSD time, but there should be an option to leave it on until I'm finished.
