Vychutnejte si věrnou reprodukci barev na tomto 25" monitoru s rozlišením QHD a velkým barevným pokrytím. 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. Podpora barev 99% pokrytí prostoru sRGB, 99% pokrytí prostoru Rec. 709, 95% pokrytí prostoru DCI-P3, Delta E < 2 (průměr) 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. It Nails the sRGB Color Space

The U2520D surpassed that, covering 99.9 percent of sRGB. 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.) 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

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 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 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 Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. 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.

Given the screen is only 60Hz, while these response times were slow for sure relative to modern gaming screens, they were still fast enough to keep up with the low 60fps frame rate. There’s no real problems with the response times here for what is an office and general use monitor. They can probably handle some light gaming if you wanted to, and are fine for multimedia and certainly for static office-type content of course. 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.

Dell U2722DE and U2722D review - TFTCentral Dell U2722DE and U2722D review - TFTCentral

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 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 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.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). 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. 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. Gaming
