Recommended brightness setting – to achieve approx 120 cd/m 2, which is the recommended luminance for LCD monitors in normal lighting conditions 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 Designed with wellness in mind: Optimize eye comfort with ComfortView Plus—an always on, built-in low blue light screen that reduces blue light emissions while delivering excellent colour . Connect to productivity: With RJ45 and USB-C®, your monitor serves as a productivity hub that delivers stable Ethernet and up to 90W of power delivery.

More monitor information like the model number, firmware version, and Service Tag can be accessed from the monitor's OSD (On-Screen Display). 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. With the stand that is attached to the monitor, you can tilt and swivel the monitor for the most comfortable viewing angle.Note: Any changes that you make are automatically saved. Whenever you move to another menu item, exit the OSD menu, or wait for the OSD menu to automatically close.

Dell has just added two monitors to the UltraSharp lineup and the main difference between them is the connectivity hub present in the U2722DE. Other than that, we have two 27-inch QHD monitors that use an IPS panel with excellent color reproduction capabilities and ComfortView Plus hardware low blue light reducing technology.A few permanently bright or dark pixels are considered normal by industry standards. The exact number of pixels that are allowed varies depending on the monitor. Refer to Dell Monitor Quality and Pixel Policy for more details. Consistent, vibrant colours: Get wide colour coverage 100% sRGB, 100% Rec.709 and 95% DCI-P3 and 1.07 billion colour depth. 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.

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 Dell UltraSharp U2722D/U2722DE/U2722DX Monitor has two built-in diagnostics that are available: If the monitor is powered-off and powered-on when displaying the Blu-Ray video, the Blu-ray player may lose the data signal from the computer to the monitor.Like the Philips 279P1, the 27-inch Dell supports 10-bit color (8 bits plus dithering), and is capable of displaying up to 1.07 billion different colors and a wide color gamut. According to the company, the display covers 100% of the sRGB color space, the color palette used for web-based photos and art, among other applications. In my testing, it covered sRGB with plenty of room to spare (140.2% of the gamut, according to the chromaticity chart replicated below).
