On the DE model the built-in‘Auto KVM’ feature detects the second connected PC and seamlessly switches controls over. You can view content from both PC sources with Picture-by-Picture (PbP) and Picture-in-Picture (PiP), and use KVM (keyboard, video and mouse) to control both PCs with a single keyboard and mouse. Another potentially useful feature for Dell laptop owners is the power on behaviour of the screen. You can simply press the monitor power button and the power sync feature seamlessly starts your monitor and connected Dell PC, even when the laptop lid is closed. This is only compatible with select Dell PCs and laptops though.

Below is a chromaticity chart of the sRGB color space, which was generated when testing in Standard mode. The area within the triangle represents all the colors that can be made by mixing the primary colors red, green, and blue. The circles, representing my measurements, mostly lie a bit outside the triangle and are fairly evenly spaced. The ‘Fast’ mode did boost the response times down to 6.7ms G2G but at the cost of some very high levels of overshoot that were distracting and problematic in practice. There were noticeable pale halos on moving content, and this mode should be avoided. We measured the input lag as pretty high as well, with a total 14.1ms display lag, and about ~9ms of that coming from signal processing lag. Another reason why it’s not suited to fast paced games.

Hard drive retention: Hard drive retention is not available on models with a soldered hard drive, including XPS 9315 2in1, Chromebooks or Venue tablets, except the Venue 11 Pro. The greyscale accuracy was poor though, and as we said some of the shades looked a little green in colour. We had a greyscale average dE of 4.7 here which isn’t very good. For an average office user there is probably no major problem here, the screen still looks good visually. It is bright out of the box at the default 75% brightness setting (255 cd/m2 measured), so that will need to be turned down. We had a decent contrast ratio for an IPS panel of 980:1 by default too which was close to the spec.

The default brightness was now a bit more modest at 203.5 cd/m2, and thankfully you do have control over the brightness control still within the OSD so you can customise this to your liking. The gamma curve looked to be delivering something closer to sRGB gamma as opposed to the specified 2.2 on the factory calibration report. Below we have re-measured relative to the sRGB gamma curve where you can see this is a closer match. Fair enough, but odd that Dell would specifically list 2.2 on the calibration report hen that isn’t what has been used seemingly. Since 2004, I have worked on PCMag’s hardware team, covering at various times printers, scanners, projectors, storage, and monitors. I currently focus my testing efforts on 3D printers, pro and productivity displays, and drives and SSDs of all sorts. While the U2722D/DE does carry a factory calibration, that is applicable only for the sRGB and Rec.709 preset modes, and the screen comes out of the box in the ‘standard’ preset mode. We tested this for completeness to show the default performance as normal.

Our sample videos looked sharp and fluid, and showed a modest improvement in contrast with the Movie HDR setting enabled. A Whiz at Image Handling

The U2520D is a good choice for a multi-monitor array. You can use the DisplayPort-out connection to daisy-chain a second monitor, which will be automatically detected and configured using Dell Express Daisy Chaining, which I first tested in the Editors’ Choice Dell 27 USB-C Monitor (P2720DC) mentioned up top.
