In testing, the display did quite well in almost every aspect. The color showed up very accurately, there was almost no noticeable backlight bleeding, and there was no ghosting at all. The only place the Hi221D really struggled was with high and low end contrast, where the display couldn't distinguish well between the brighter bright colors and the darker dark ones. With a new color profile from the Datacolor Spyder3, this problem was remedied slightly, but it was still not the best contrast performance I've seen, especially for a 1000:1 contrast ratio.
With the speakers on the Hi221D, you really get what you pay for. Built in speaker monitors are never very good, and that was the case here, but they get the job done for everyday tasks like listening to online voicemail, interactive websites and the like.
Gaming and video watching were quite enjoyable on this display, in major part due to the lack of ghosting. On other displays, it is very easy to pick out where the monitor is falling behind, and where your pictures are dragging, but the 5ms response time advertised on the Hi221D is most certainly trustworthy.
At only about $180 USD on Geeks.com, the Hanns-G Hi221D is a superb monitor for the price, and should definitely be on your list if you're in the market for a 22” widescreen display. The Hi221D earns the OCIA.net Seal of Approval.
