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.pdf 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.) 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.

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. 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. 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.

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 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. 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. 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.

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. Podpora barev 99% pokrytí prostoru sRGB, 99% pokrytí prostoru Rec. 709, 95% pokrytí prostoru DCI-P3, Delta E < 2 (průměr) 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.
