Dell Home offers its Dell UltraSharp P2415Q 23.8" 4K Ultra HD IPS LED-Backlit LCD Monitor for $449.99 with free shipping. That's the lowest total price we could find by $88, although we saw it bundled with a $150 gift card for $80 more last week. 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.
