Dell had quite the deal for Cyber Monday, offering its P2815Q monitor for just $299.99. The 28-inch 4K display is normally $449.99, so Dell was knocking off a considerable 40% for the sale.
While it might sound like an amazing deal, remember that this is a 30Hz panel, and not a 60Hz panel that you'd want for gaming or photo/video editing, as it's also a TN-based display. On the upside, the Dell P2815Q does offer pivot, tilt, swivel, and cable management options, as well as being height adjustable.
On the display connectivity side of things, Dell has DisplayPort mini Display Port, HDMI (MHL), DisplayPort out (MST), USB Upstream and four USB 3.0 ports.
