Dell is introducing its new Dell UltraSharp 40 Curved Thunderbolt Hub monitor at CES 2024 next week. The monitor, model number U4025QW, is the world’s first 40-inch 5K monitor to have TÜV Rheinland five-star eye comfort certification. This is a new industry standard for eye comfort to help reduce signs of eye fatigue.
Eye health
As part of the five-star certification, Dell doubled the monitor’s refresh rate from 60Hz to 120Hz. This delivers smoother and sharper moving images. The monitor also has a built-in ambient light sensor which adjusts screen brightness and color temperature depending upon the light in the room. This can reduce eye fatigue by 7% to 17% compared to a screen with constant brightness. In addition, Dell ComfortView Plus reduces harmful blue light exposure by utilizing a more advanced LED backlight. This can reduce eye fatigue by 8% after 50 minutes of performing a search task.
Color accuracy
The Dell UltraSharp 40 Curved Thunderbolt Hub monitor has a high level of color accuracy. The monitor can display 99% of the DCI-P3 color space. DCI-P3 is an RGB color space defined for digital theatrical motion picture distribution. This means that the new monitor should be ideal for video editors. You can also easily calibrate the colors on the screen with Dell’s Color Management software. In addition, the UltraSharp 40 monitor is VESA DisplayHDR 600 certified with IPS Black technology and a 2,000:1 contrast ratio.
Connectivity
As the name suggests, the Dell UltraSharp 40 Curved Thunderbolt Hub monitor supports Thunderbolt 4. This means you can connect the monitor via a single Thunderbolt cable with up to 140W power delivery. The UltraSharp 40 monitor also supports HDMI 2.1 FRL (Fixed Rate Link) and DisplayPort 1.4 for smooth image transmission, minimizing any loss in visual quality. In addition, the monitor includes high-speed wired Ethernet connectivity at 2.5 Gbps via an RJ45 port. There are front-facing quick access ports so you can easily connect your external devices.
Sustainability

The Dell UltraSharp 40 Curved Thunderbolt Hub monitor has a platinum silver finish which gives it a clean look. The monitor is also made from 85% post-consumer recycled (PCR) plastic and 100% recycled aluminum. In addition, the UltraSharp 40 monitor meets the latest environmental standards including EnergyStar and TCO Certified Edge, and is EPEAT Gold registered.
UltraSharp 34
If you prefer a smaller display, Dell is also launching the U3425WE Ultrasharp 34 Curved Thunderbolt Hub monitor. This has a 34-inch screen with a WQHD resolution of 3440 by1440 pixels. However, it still has many of the features of the larger U4025QW including TUV Rheinland five-star eye comfort certification and IPS Black technology. The Ultrasharp 34 monitor also offers Thunderbolt 4 connectivity with up to 90W power delivery.
What we think
Dell’s new UltraSharp curved monitors deliver the high levels of color accuracy that you need for video editing. In addition, Dell deserves recognition for the steps they have taken to use recycled materials in the UltraSharp monitors. The monitors are premium products with prices to match. However, you will spend a lot of hours staring at your screen as you edit. As such, it’s also good to know that your eyes are better protected from fatigue while you work.
