TechReviewSource.com posted a review on the Dell UltraSharp U2713HM

Dell's UltraSharp series of monitors have snagged quite a few Editors' Choice awards over the years, and with good reason; models such as the Dell UltraSharp 2408WFP, Dell UltraSharp U2711, and Dell UltraSharp U3011 have all earned high marks for their solid performance and superb features. The Dell UltraSharp U2713HM ($799 direct) is the latest addition to the UltraSharp line, and like its predecessors, it rocks.

As with the Dell U2711, the U2713HM uses a 27-inch IPS panel, only this time it's an AH-IPS (Advanced High Performance) panel rather than a P-IPS (Professional) panel, and it uses LED backlighting instead of CCFL backlighting. AH-IPS is a fairly recent (2011) panel technology that boasts superb color accuracy and wide viewing angles and is meant to be more energy efficient than previous IPS technologies. Indeed, the U2713HM delivers excellent color fidelity which remains true when viewed from an extreme angle, and while not exactly a power miser, it uses less power than several recently reviewed IPS displays. The 2,560-by-1,440 display comes pre-calibrated at the factory and is equipped with virtually every input port you'll need, and it comes with a built-in USB 3.0 hub. Its dark grayscale performance could be better though, and you have to manually change the screen orientation when pivoting the display.[/wuote]
