While using it with MacOS, the text has the same size as my MacBook. This can lead to eye strain after longer periods of time if you are not close to the monitor (unless you have eagle eyes). If you use scaling, the image quality will suffer a lot. 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.

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. 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.

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 Výjimečné barvy: Získejte široké pokrytí barev díky 95% pokrytí prostoru DCI-P3 – zhruba o 25 % více než u sRGB – pro skutečnou reprodukci barev.

Ports: Power Delivery and Daisy Chaining

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.

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. 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.

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 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. Vychutnejte si věrnou reprodukci barev na tomto 25" monitoru s rozlišením QHD a velkým barevným pokrytím. 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. Doposud jsem používal pro práci UltraSharp U2412M, který byl také vhodný pro tisk fotografií. Model UltraSharp U2520D má o něco vyšší rozlišení a je "širokoúhlejší", takže předpokládám lepší práci s fotografiemi a videi.

Sharp Images and a 'Beveled Bezel'

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.

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.

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 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. 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. Recommended brightness setting – to achieve approx 120 cd/m 2, which is the recommended luminance for LCD monitors in normal lighting conditions

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. Normal mode delivered pretty slow response times though, with a 10.4ms G2G average but thankfully very low levels of overshoot that were not visible in practice at all. 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.

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. 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.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.
