Ahead of this year’s CES, Dell has unveiled its latest addition to the UltraSharp monitor series with the introduction of the 40-inch UltraSharp 40 Curved Thunderbolt Hub Monitor (U4025QW), designed to prioritize eye comfort and productivity. 

This new monitor, alongside the 34-inch UltraSharp 34 Curved Thunderbolt Hub Monitor (U3425WE), is set to hit the market next month and is aimed at content creators, data scientists, and engineers. While gaming-friendly features are present, the primary focus here is to minimize eye strain and enhance the overall user experience.

One notable aspect of the UltraSharp 40 Curved Thunderbolt Hub Monitor and its smaller sibling is their 120Hz refresh rate, a move by Dell to provide smoother visuals and reduce eye fatigue. 

Both models come with an ambient light sensor, allowing automatic adjustments to screen brightness and color temperature according to the surrounding lighting conditions. Dell cites studies suggesting that this technology can reduce the frequency of eye fatigue signs by up to 17 percent.

The key highlight is Dell's commitment to achieving a five-star eye comfort certification from TUV Rheinland, a new industry standard. This certification ensures that the displays are designed to help reduce signs of eye fatigue. 

Achieving this certification involved doubling the refresh rate, incorporating an ambient light sensor, and upgrading ComfortView Plus technology to reduce blue light exposure from 50 percent to under 35 percent.

In terms of specifications, the UltraSharp 40 Curved Thunderbolt Hub Monitor boasts a "5K" resolution of 5120 x 2160 and is VESA DisplayHDR 600 certified, with a peak brightness of over 600 nits. Its Thunderbolt 4 connection can deliver up to 140W of power to a connected laptop, making it a versatile hub for various devices. It also supports variable refresh rates over HDMI 2.1.

On the other hand, the 34-inch model features a lower 3440 x 1440 resolution and can deliver up to 90W over Thunderbolt 4. It lacks a DisplayHDR certification and support for variable refresh rates over HDMI.

Both monitors offer a similar range of features, including 2.5Gbps Ethernet ports, DisplayPort 1.4, built-in USB-A and USB-C ports that offer up to 15W of power and 10Gbps of data transfer, and multitasking capabilities for connecting two computers simultaneously.

The UltraSharp 40 Curved Thunderbolt Hub Monitor (U4025QW) and the UltraSharp 34 Curved Thunderbolt Hub Monitor (U3425WE) will be available globally from February 27th. The larger model starts at $2,399.99, while the smaller one is priced at $1,019.99.
