It seems that Dell is finally ready to replace the U4021QW, a 40-inch curved monitor that it introduced during CES 2021. Although the new UltraSharp 40 is rumoured to output at 5K like its predecessor, Dell has updated its large professional monitor in various areas.

Windows Report has managed to obtain early details about a new 40-inch Dell UltraSharp monitor. For reference, the website has also leaked information about three new Alienware gaming laptops, two gaming monitors and multiple upcoming Dell XPS laptops. As far as we can tell, the new UltraSharp monitor will succeed the U4021QW, a monitor that debuted during CES 2021 and one that still sells for US$1,750 on Amazon.

Seemingly, Dell will market the U4021QW replacement as the 'UltraSharp 40 Hub Monitor', although Windows Report also refers to the monitor as the 'UltraSharp 40 Curved Thunderbolt Hub Monitor'. Regardless, the new UltraSharp monitor retains its predecessor's 5K resolution, actually 5,210 x 2,160 pixels. Unfortunately, it remains to be seen whether Dell has improved upon the 60 Hz refresh rate and 5 ms GtG response times that it afforded its predecessor.

Additionally, it appears that Dell has positioned some ports between generations, with a three-port USB hub visible in the sole image that Windows Report has shared so far. Moreover, Windows Report states that the 40-inch monitor will arrive with TÜV Rheinland 5-star Eye Comfort, a certification that Dell showcased earlier this month with the UltraSharp U2724D and UltraSharp U2724DE. Please see the excerpt below for TÜV Rheinland's explanation about its new eye comfort certification. Allegedly, the new UltraSharp 40 could be ready before CES 2024; Windows Report has not provided a full release date yet, though.

The 'Eye Comfort' certification process examines three technical dimensions (image quality, ambient light management, eye care technology) and 15 different test categories that have shown to have a significant impact on eye comfort. Features like good image quality, high refresh rate and good ambient light management, such as intelligent brightness and CCT adaptation to ambient light, help reduce visual fatigue...Only if a screen achieves a 5-star rating in all 15 categories will the overall result also be a 5-star rating...For example, a 5 Star 'Eye Comfort' Certified monitor has a high refresh rate (≥ 120 Hz) and high color accuracy. It also has hardware to reduce blue light and flicker, as well as brightness and color temperature control for ambient lighting. These features enhance health protection and reduce visual fatigue.
