Provantage offers the Dell UltraSharp UP2414Q 23.8" 4K Ultra HD IPS LED-Backlit LCD Monitor for $682.95 plus $19.95 for shipping. That's $97 under our July mention (although that was bundled with a gift card) and $24 under the lowest total price we could find today. (For further comparison, we saw it for $765 shipped without a gift card in May.) It features a 3840x2160 native resolution (four times that of 1080p), LED backlight, 4-port USB 3.0 hub, and DisplayPort, mini DisplayPort, and HDMI inputs.
