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. Turn off your monitor and reconnect the video cable: then turn on both your computer and the monitor.

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. 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. In-Plane Switching technology: See consistent colour and picture quality across a wide 178/178 degree viewing angle. To navigate the On-Screen Display (OSD) menu, use the buttons on the monitor. The monitor control buttons are usually on the right side, either on the side, front, or bottom of the monitor. To access the On-Screen Display (OSD) menu, press Button 5 on the monitor. Built-In Self-Test - The Dell UltraSharp U2722D/U2722DE/U2722DX Monitor has a built-in self-test that helps you identify if the screen abnormality is with the monitor or the video card (GPU) on your computer. When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade.It is always a good practice to isolate the monitor by running the Built-In Diagnostics.

dE colour accuracy – a wide range of colours are tested and the colour accuracy dE measured. We compare these produced colours to the sRGB reference space, and if applicable when measuring a wide gamut screen we also provide the accuracy relative to a specific wide gamut reference such as DCI-P3. An average dE and maximum dE is provided along with an overall screen rating. The lower the dE the better with differences of <1 being imperceptible (marked by the green area on the graph), and differences between 1 and 3 being small (yellow areas). Anything over dE 3 needs correcting and causes more obvious differences in appearance relative to what should be shown Note: The Dell UltraSharp U2722D/U2722DE/U2722DX Monitor is heavy; handle with extreme care. It is recommended to have two peoplelift or move this monitor.

Dim or discolored video can be caused by the video cable, so try reseating the cable and swapping with a known good part. In-Plane Switching technology: See consistent color and picture quality across a wide 178/178 degree viewing angle. When you close and then reopen the lid on a laptop, the Connecting and Configuring Displays (CCD) feature in Windows automatically reverts the display mode to the last active selection. This behavior is by design in Microsoft Windows. 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.With the stand that is attached to the monitor, you can tilt and swivel the monitor for the most comfortable viewing angle. Wireless USB peripherals responding slowly or only working as the distance between themselves and their receiver decreases.

To learn more about connecting your monitor to the personal computer, refer to the Dell knowledge-base article: How do I connect a monitor to a personal computer? 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. Jumpstart productivity: Simply press the monitor power button and the power sync feature seamlessly starts your monitor and connected Dell PC, even when the laptop lid is closed. Compatible with select Dell PCs.
