In the run-up to the Virtual CES 2021, Dell has called a series of new business monitors, including the Oberlashemodell Ultrasharp U4021QW. It represents as a third display the highest 21: 9 resolution of 5120 × 2160 pixels – the first to the three monitors on a diagonal of rounded 40 inches (39.7 inches).
A factory-calibrated IPS panel is used, which should have a maximum delta-E color deviation of 2 in SRGB mode. The latter color space covers the ultrasharp U4021QW complete, DCI-P3 to 98 percent. The display shows 1.07 billion colors, but Dell did not betray whether the above a real 10-bit processing per color channel or frame rate control (FRC) is done.
The refresh rate is 60 Hertz, the brightness at 300 cd / m² and the contrast with IPS-typical 1000: 1. With a reaction time of 5 ms at normal overdrive setting, the monitor is given to the rather slow representatives of its kind.
Thunderbolt 3 docking station
The UltrashArP U4021QW comes with numerous connections therefore to use it as a docking station – such as a note or MacBook with Thunderbolt-3 connection. The latter can be displayed display-1.4-image signal and data, and the monitor can load an attached device with up to 90 watts.

In addition, on board: six times USB 3.2 GEN 2 (10 GBIT / S), including a type C connection, audio pawline and a RJ45 Ethernet port. If the connected PC can not deal with Thunderbolt 3, the stroke can be interrupted by a USB type B connection. The image signal then takes the display via DisplayPort 1.4 or on 30 Hertz limits over HDMI 2.0. Two integrated 9-watt speakers complete the equipment.
The ultrasharp U4021QW in itself: Dell recommends $ 2100, converted including 19 percent VAT (not included in US prices) approximately 2040 euros. The delivery should begin at the end of January 2021. Gunstiger are some more contaminated Ultrasharp monitors such as the U3821DW for $ 1500, but with lower resolution (here 3840 × 1600 pixels) and without Thunderbolt 3. LGS 34WK95U with 5120 × 2160 pixels and Thunderbolt 3 is from just under 1000 euros relevant.
