The U2520D handled both still and moving images well. Colors looked reasonably true and rich, and both contrast and dynamic range were spot-on. 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 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 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.
UltraSharp 25 QHD USB-C Monitor: U2520D | Dell UK
Gamut coverage – we provide measurements of the screens colour gamut relative to various reference spaces including sRGB, DCI-P3, Adobe RGB and Rec.2020. Coverage is shown in absolute numbers as well as relative, which helps identify where the coverage extends beyond a given reference space. A CIE-1976 chromaticity diagram (which provides improved accuracy compared with older CIE-1931 methods) is included which provides a visual representation of the monitors colour gamut as compared with sRGB, and if appropriate also relative to a wide gamut reference space such as DCI-P3. 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.Působivá čistota: Sledujte jemné detaily s rozlišením QHD (2 560 × 1 440) a vysokou hustotou obrazových bodů 117,5 ppi.

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.Dell claims color-gamut coverage of 99 percent of the sRGB color space, the standard color space used on the web and in many other applications, out of the box. The U2520D surpassed that, covering 99.9 percent of sRGB. 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. 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.

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. (See how we test monitors.) Recommended brightness setting – to achieve approx 120 cd/m 2, which is the recommended luminance for LCD monitors in normal lighting conditions Přesné 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.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 buttons make it easy to navigate through the OSD. You can change color space, input source, brightness, contrast, and a host of other parameters. Note that if you daisy-chain a second monitor, you will first want to enable the MST setting in the Display menu.

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 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.

Vychutnejte si věrnou reprodukci barev na tomto 25" monitoru s rozlišením QHD a velkým barevným pokrytím. Skvělá barevná hloubka: Díky úžasné barevné hloubce, mimořádnému jasu ve špičkách a kontrastnímu poměru 1 000 : 1 má obraz věrné barvy. Připravte se na lepší barevné přechody a přesnost s více odstíny na tomto monitoru VESA DisplayHDR™ 400. Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test.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 Podpora barev 99% pokrytí prostoru sRGB, 99% pokrytí prostoru Rec. 709, 95% pokrytí prostoru DCI-P3, Delta E < 2 (průměr)
