The pivot mode allows you to rotate the panel into portrait mode to gain easier access to the other ports. The real killer feature is USB Type-C support, which effectively means this screen can turn into a docking station at your desk.

A 37-millisecond input lag (the time it takes for the monitor to react to a controller command), which I measured using a Leo Bodnar Video Signal Lag Tester , is at the high end of acceptable lag; our fastest monitors, the BenQ XL2430T and the SW2700PT, measured 9. This 27-inch display uses an In-Plane Switching (IPS) panel to deliver accurate colors and precise grayscale performance, and its bezel-free design offers a (mostly) seamless fit when used in a multi-monitor setup. The 27-inch in-plane switching (IPS) flat panel has a native resolution of 2,560 by 1,440 pixels, known as QHD or 1440p, at a 16:9 widescreen aspect ratio. The first sign of this is the tiny rectangular footprint, which is roughly the size of an A5 sheet of paper. Dell rates the U2719D at 350 nits (candelas per meter squared) of luminance, but it fell well short of that: 258 nits, in my testing.

The 27-inch WQHD (2,560-by-1,440) panel has a non-reflective coating, a peak brightness of 350 cd/m2, a 1,000:1 native contrast ratio, and a 16:9 aspect ratio. I tested brightness, contrast ratio, and color accuracy using our standard test equipment: a Klein K-10A colorimeter, a Murideo Six-G signal generator, and Portrait Displays' Calman 5 display-calibration software. Take it as a pinch of salt though as I'm just stating my observations and not with a colour checker. But if you can find the U2719D at a significant discount versus the P2720DC, and you are sure you won't need the USB-C connectivity, you should be more than happy with this model. hub—with one USB upstream port and four USB downstream ports—for charging devices and attaching peripherals.

I've also written a host of articles about astronomy, space science, travel photography, and astrophotography for PCMag and its past and present sibling publications (among them, Mashable and ExtremeTech), as well as for the PCMag Digital Edition.

Its IPS panel delivers outstanding color and grayscale performance, wide viewing angles, and a crisp WQHD picture, and it has multiple video inputs, a video output, and a four-port USB hub. I've connected the monitor's USB upstream port to the tower with the enclosed USB cable and the sound bar's USB cable to one of the monitor's downstream ports. The latter promises reduced blue light emissions, which some people find helpful if using a monitor for long periods.
