Newegg via eBay offers the Samsung 28" 4K Ultra 2160p LED-Backlit LCD Monitor, model no. U28D590D, for $549.99 with free shipping. That's the lowest total price we could find by $50, although it was $20 less last week (since expired). It features a 3840x2160 native resolution (four times that of 1080p), LED backlight, two HDMI ports, and DisplayPort.
