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. The U2722D/DE use an IPS technology panel (panel part LG.Display LM270WQ8-SSA1) and offers a 2560 x 1440 (Quad HD) resolution. There is a wide colour gamut promoted which offers a 95% DCI-P3 coverage, along with 100% of the sRGB space. The screen also comes factory calibrated, with a report provided in the box confirming it has been calibrated in the sRGB and Rec.709 preset modes. In other specs there are typical IPS performance metrics like a 5ms G2G response time (in ‘fast’ mode), 1000:1 contrast ratio, 350 cd/m2 brightness, 178/178 viewing angles and 10-bit colour depth. Ports shown from the DE model, some are not included in the lower cost D model Podpora barev 99% pokrytí prostoru sRGB, 99% pokrytí prostoru Rec. 709, 95% pokrytí prostoru DCI-P3, Delta E < 2 (průměr) If you’re looking for a compact but elite productivity monitor that displays color well, the U2520D is well worth your consideration. It costs less than the Lenovo P27u-10, and it features much better OSD navigation. It has a similar feature set but a smaller screen than the Editors’ Choice Dell 27 USB-C Monitor (P2720DC). They both have very good color accuracy, a full range of ergonomic features, and a generous port selection, plus both support automatic daisy chaining of a second monitor.

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. The OSD: Intuitive Navigation At the maximum refresh rate of the screen we will also include our familiar more detailed response time measurements, which includes a wider range of transition measurements as well as some analysis of things like the refresh rate compliance. This identifies how many of the measured pixel transitions were fast enough to keep up with the frame rate of the screen. Ideally you’d want pixel response times to be consistently and reliably shorter than this refresh rate cycle, otherwise if they are slower it can lead to additional smearing and blurring on moving content.All other products will be delivered via the fastest available method (excluding bank holidays and weekends) and generally within 3-5 days, depending on customer location. 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.

Vychutnejte si věrnou reprodukci barev na tomto 25" monitoru s rozlišením QHD a velkým barevným pokrytím. 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. Navigation through the U2520D’s onscreen display (OSD) is easy and intuitive. It is controlled by four small, physical buttons next to the power button on the right side of the monitor’s bottom bezel. When you press any of them, all four buttons become labeled by illuminated icons above them. Once you enter the menu system, they are identified by up, down, and right arrows, plus close.Built in KVM and RJ45 along with USB type-C hub (inc DP Alt mode and 90W power delivery) – DE model only Recommended brightness setting – to achieve approx 120 cd/m 2, which is the recommended luminance for LCD monitors in normal lighting conditions Default setup was moderate overall. There was a reasonable gamma, being measured at 2.10 average overall and being a bit too low from our target of 2.2. This was lowest in the darker tones (2.07 average) which could lead to a little loss in shadow detail. The RGB balance wasn’t very good and some of the grey shades looked a little green in colour. You can see the green balance was relatively too high in the middle graph. There was a reasonable overall greyscale colour temp with 6241k measured, being a little too warm but nothing too severe. The white point was very accurate at 6527k though (0% deviance). Rated luminance and contrast ratio are 350 nits (candelas per meter squared) and 1,000:1, respectively. In Standard mode, it turned in 280 nits, a bit shy of its Dell rating but still bright enough for its intended tasks, and an 1,141:1 contrast ratio, somewhat better than its rating.
