Dell has introduced new 27-inch and 32-inch monitors in its UltraSharp lineup tailored primarily towards multimedia consumption and not-so-demanding gamers. The 27-inch lineup is comprised of 2K and 4K IPS monitors with support for AMD FreeSync while the 32-inch variant is a curved 4K VA panel.

So they bump up the S series 27" $180 from 1080p to 2k, give it a slight curve and keep everything else the same, and then charge $420? I'm starting to believe Dell will never raise about the 350 nit brightnesses on their monitors.
