On certain videos and applications with fast-moving images, imaging ghosting, which appears as a trailing shadow, may occur. Picture In Picture and Picture by Picture could be useful for multi-tasking and viewing multiple inputs at once, although keep in mind the screen is still only 27″ which is fairly small by today’s standards. No Video - You are unable to see any display on the screen, able to hear the windows chime but no display is seen. 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.
The lower the dE the better with differences of <1 being imperceptible (marked by the green line on the graph), and differences between 1 and 3 being small (below the yellow line). This is a shorter format review but we have included as much of our normal testing and results as we can, especially in relevant areas for this screen. More ways to manage: Asset management reports allow IT managers to quickly capture and track monitor information as well as configure multiple monitors at once through a single setup.The Troubleshooting section of this Dell knowledge-base article provides information about troubleshooting common issues with the Dell UltraSharp U2722D/U2722DE/U2722DX Monitor. I currently focus my testing efforts on 3D printers, pro and productivity displays, and drives and SSDs of all sorts. 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 color. For help with video or display issues such as no video or no display, blank or black screen, flickering, resolution or color issues, horizontal or vertical lines, etc.
For measurement we use a UPRtek MK550T spectroradiometer which is particularly good for colour gamut and spectrum measurements. There is a focus from this screen on low blue light capabilities, but not in the usual way you see from many displays. In wide gamut mode you’d also need some way to calibrate and profile the screen for colour aware applications to improve the accuracy. Using the Joystick control, highlight the Diagnostics option and press the Joystick button to start the diagnostics.AMD, and the AMD Arrow logo, and combinations thereof are trademarks of Advanced Micro Devices, Inc. The default ‘standard’ mode carries the screen’s full native colour gamut and we measured a wide coverage here as suggested by the spec. Note that the U2722D/DE doesn’t seem to have been certified under the Eyesafe program, but there is talk about the ‘ComfortView Plus’ low blue light capabilities on the product page. Dell backs the UltraSharp 27 USB-C Hub Monitor with a three-year warranty, which is typical of productivity monitors. Instead the focus is on providing a backlight where the blue light spectral peak has been shifted to a reportedly less harmful frequency, away 415 – 455nm area.
