Dell 40″-120Hz Ultrasharp gets resolution of 5120×2160 pixels and Thunderbolt 4

In the run-up to the CES trade fair, Dell has introduced a 40″ curved UltraSharp monitor with a resolution of 5120×2160 pixels, a 120Hz refresh rate and a Thunderbolt 4 hub. A 34″ variant with a resolution of 3440×1440 will also be available pixels.

The UltraSharp monitors, named U4025QW and U3425WE, have an IPS Black panel that enables a contrast ratio of 2000:1. The screens can also display 99 percent of the DCI-P3 color space and support 10bit color, which means they can display 1.07 billion color gradations. The DisplayHDR 600 certification of both screens means that a peak brightness of 600cd/m² can be achieved. The 40″ screen supports hardware calibration using Dell Color Management software and a separately available colorimeter.

Dell states that it has made some adjustments compared to its predecessors, U4924DW and U3423WE, to improve eye comfort. In addition to doubling the refresh rate to 120Hz, an ambient light sensor is built in, which automatically adjusts the brightness of the screen to the lighting conditions. In addition, the ComfortView Plus technology, which reduces blue light radiation, has been improved. According to Dell, the monitor displays 35 percent blue light, while previously it was 50 percent.

The screens also serve as Thunderbolt 4 hubs. There is a 2.5Gbit/s Ethernet port, as well as connections for HDMI 2.1 and DisplayPort 1.4. Two USB-C and four USB-A ports have also been added. The hub of the 40″ version contains a power supply with a maximum power of 140W, while the 34″ monitor has a maximum power of 90W.

The two UltraSharp screens should become generally available on February 27. In the US, the 40″ monitor costs $2400 and the 34″ variant costs $1020. European prices have not yet been announced.
