Dell Home continues to offer its Dell UltraSharp P2415Q 23.8" 4K Ultra HD IPS LED-Backlit LCD Monitor for $479.99. Coupon code "P43LD0MQJLGB33" cuts it to $431.99.

It features a 3840x2160 native resolution (four times that of 1080p), LED backlight, anti-glare, four USB 3.0 downstream ports, one USB upstream port, DisplayPort, mini DisplayPort, and HDMI. Deal ends February 18.
