The Dell Ultra Sharp U2717D offers a higher Quad HD resolution with slightly better pixel density, and I find that both make a noticeable improvement compared to its predecessors.The Dell Ultra Sharp U2717D is a little sharper and gives you a nontrivial increase in display area while maintaining the same level of performance with the previous models Most of monitor setup is really putting together the base; beyond that, you mount the display on the base and make the relevant connections. Putting together the stand and mounting the display is easy. You simply drop the vertical mount onto the base and screw it on with the captive thumbscrew. The display's VESA-mount back simply snaps onto the stand. You feed the cables through a hole in the back. It rotates and tilts smoothly, even one-handed, including 90-degree rotation for using it vertically, or for bringing the connectors to the side so you can see them. There's also a fair bit of latitude for height adjustments.
