Dell has announced the 34-inch curved Dell U3421WE, a monitor designed to meet the needs of professional users with its 21:9 ultrawide-QHD resolution (3,440 x 1,440 pixels), 10-bit color depth and 95% support for the DCI-P3 color space (as well as 99% sRGB and 99% Rec.709). However, the typical brightness is only 300 nits - HDR is not supported. The monitor is factory calibrated and has an average color deviation of less than 2 Delta-E for sRGB and less than 3 for DCI-P3.

Because Dell is targeting business users with the monitor, a KVM switch is built in that allows users to switch between operating two different PCs connected to the monitor using just one mouse and keyboard. Also supported is a Picture-by-Picture and Picture-in-Picture function to display the image of two connected computers simultaneously.
Its interfaces include two HDMI 2.0 read and two DisplayPort 1.4 inputs, a USB-C input with alternate mode with DisplayPort 1.4 and up to 90 watts of power delivery, a USB-C access for daisy-chaining additional USB devices, as well as a USB 3.2 Gen 1 (5 Gbps) hub with four downstream ports (USB Type-A) and an RJ45 Ethernet output (which is made available to a PC via USB-C - the monitor acts as a hub). For optimal ergonomics, the U3421WE can be tilted between -5 and +21 degrees, adjusted by 150 mm in height and rotated by 30 degrees in both directions.

The Dell U3421WE monitor is scheduled to be released on December 1 at a price of €1,030. Some professional features such as support for true HDR including high brightness and local dimming via mini LED zones, Thunderbolt 3 or an integrated colorimeter are unfortunately not included at this price. Who needs these features is better advised with the approximately 4.500 Euro expensive 
Dell UltraSharp UP3221Q 4K 32" professional monitor with 2.000 mini LED zones, Thunderbolt and colorimeter.
