Výjimečné barvy: Získejte široké pokrytí barev díky 95% pokrytí prostoru DCI-P3 – zhruba o 25 % více než u sRGB – pro skutečnou reprodukci barev. Tento monitor nabízí také 99% pokrytí barevného prostoru sRGB a 99% pokrytí prostoru Rec. 709. 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. dE colour accuracy – a wide range of colours are tested and the colour accuracy dE measured. We compare these produced colours to the sRGB reference space, and if applicable when measuring a wide gamut screen we also provide the accuracy relative to a specific wide gamut reference such as DCI-P3. An average dE and maximum dE is provided along with an overall screen rating. The lower the dE the better with differences of <1 being imperceptible (marked by the green area on the graph), and differences between 1 and 3 being small (yellow areas). Anything over dE 3 needs correcting and causes more obvious differences in appearance relative to what should be shown 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.

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. There are only two overdrive settings available in the menu via the ‘Response Time’ option. These are for ‘normal’ (8ms G2G spec from Dell) and ‘Fast’ (5ms G2G from Dell) modes. We tested both of these and it was immediately obvious that the ‘Fast’ mode was like many other aggressive overdrive settings in the market and not usable in practice. The ‘normal’ mode looked far better. 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. Vychutnejte si věrnou reprodukci barev na tomto 25" monitoru s rozlišením QHD a velkým barevným pokrytím. Calibration and profiling can of course produce excellent results if you have a suitable calibration device and appropriate software. Our results are included above. You can see the recommended OSD settings above, and then further corrections are taken care of at the profile level. If you want you can also try our calibrated ICC profileout. GamingPřesné barvy ihned po vybalení: Monitor je ve výrobě kalibrován na 99% pokrytí barevného prostoru sRGB s přesností Delta-E menší než 2 pro přesné barvy hned od začátku. 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.

Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. The U2520D has a VESA DisplayHDR 400 rating, the most basic level of VESA’s HDR scale. It has several HDR settings: DisplayHDR, Movie HDR, and Game HDR. It’s worth experimenting with them to see which you find the most pleasing. 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. Conclusion IDC Whitepaper: “Optimizing Performance with Frequent Server Replacements for Enterprises” commissioned by Dell Technologies and Intel, March 2021. Results are based on interviews with 18 IT practitioners and decision makers at midsize and large enterprises and a web survey of 707 IT practitioners and decision makers at midsize and larger enterprises using Dell Technologies server solutions across 7 industries. See full whitepaper: https://www.delltechnologies.com/resources/en-us/asset/white-papers/products/servers/server-infrastructure-resiliency-enterprise-whitepaper.pdfWhile 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.

Built in KVM and RJ45 along with USB type-C hub (inc DP Alt mode and 90W power delivery) – DE model only Over the years, I have reviewed iPad and iPhone science apps, plus the occasional camera, laptop, keyboard, and mouse. 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. 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 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.

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.
