There will soon be a ton of new monitors competing for your attention because CES is almost here, among other things. With the UltraSharp 40 Curved Thunderbolt Hub Monitor, Dell hopes to make a big impression. This device, which Dell claims to be the “first 40-inch 5K monitor certified for five-star eye comfort,” was unveiled only a few days before CES 2024 gets underway.

TUV Rheinland has set a new industry benchmark for five-star eye comfort. Emphasizing displays that aid in lowering symptoms of eye tiredness is the goal. With regard to the most recent UltraSharp monitors, Dell claims to have taken three steps to obtain this certification. To get smoother graphics, it first doubled the refresh rate to 120Hz. Because of the ambient light sensor built into it, the monitors can automatically change the color temperature and brightness of the screen to suit the surrounding lighting. According to research cited by Dell, doing so may help lower the frequency of symptoms of eye fatigue by as much as 17%.

Finally, Dell claims to have improved the ComfortView Plus technology by lowering the percentage of blue light exposure from 50% to less than 35% with the aid of an enhanced LED backlight. Additionally, this can lessen the symptoms of eye fatigue.

The performance of the display shouldn’t be affected by any of those. 1.07 billion colors and a 99 percent DCI-P3 / Display P3 color space are claimed by Dell for the UltraSharp 40 Curved Thunderbolt Hub. It has a 2,000:1 contrast ratio, IPS Black Panel technology, and is certified by VESA DisplayHDR 600.

Regarding connectivity, Thunderbolt 4 is supported, providing up to 140W of power delivery. There are HDMI 2.1 and DisplayPort 2.1 connections, and speeds of up to 2.5 Gbps are possible over an Ethernet connection. Pop-out front-facing USB-A and USB-C ports, according to Dell, should make connecting and charging your devices simple.

Should the 40-inch model prove to be too large for your requirements, you may want to take into account Dell’s 34-inch model instead. In addition, the UltraSharp 34 Curved Thunderbolt Hub Monitor boasts Thunderbolt 4 connectivity, IPS Black technology, and a five-star eye comfort certification from TUV Rheinland. Nevertheless, with a WQHD resolution of 2,560 x 1,440, it is not a 5K monitor.

Global availability for both monitors is scheduled to begin on February 27. In the US, the UltraSharp 40 Curved Thunderbolt Hub Monitor is priced at $2,400; in Canada, it is $3,290 CAD. The price of the 34-inch model is $1,020 in the US and $1,400 CAD outside of the US.
