Dell’s new 120Hz ultrawide monitors max out at 40 inches and 5K

Dell has a pair of new ultrawide monitors it’s showing off ahead of CES, the 40-inch UltraSharp 40 Curved Thunderbolt Hub Monitor (U4025QW) and the 34-inch UltraSharp 34 Curved Thunderbolt Hub Monitor (U3425WE). They’re going on sale next month, with the larger model starting at $2,399.99, and the smaller at $1,019.99.

Although Dell’s announcement blog post notes that the monitors are targeting the likes of content creators, data scientists, and engineers rather than gamers, both monitors come with gaming-friendly 120Hz refresh rates. It’s a part of Dell’s aim for them to minimize eye-strain. To this end, they both also feature reduced blue light output, and have built-in ambient light sensors that adjust brightness and color temperatures on the fly. The monitors have been given a five-star certification for eye comfort by the testing organization TÜV Rheinland.

As well as their screen sizes, there are a few other differences worth noting between the two monitors. The 40-inch model has a “5K” resolution of 5120 x 2160, and its LCD display can hit a peak brightness of over 600 nits judging by its DisplayHDR 600 certification. Its Thunderbolt 4 connection can deliver up to 140W of power to a connected laptop, and its spec sheet mentions support for variable refresh rates over its HDMI 2.1 connection. 

Meanwhile the 34-inch’s LCD screen has a lower 3440 x 1440 resolution, and can only deliver up to 90W of over Thunderbolt 4. Its spec sheet also doesn’t mention a DisplayHDR certification, nor support for variable refresh rates over HDMI. 

Otherwise both monitors offer a similar range of specs 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 various multitasking features if you want to connect two computers simultaneously. 

Both the UltraSharp 40 Curved Thunderbolt Hub Monitor (U4025QW) and the UltraSharp 34 Curved Thunderbolt Hub Monitor (U3425WE) will be available globally from February 27th.
