To date, TÜV Rheinland only has certified monitors (either standalone or mobile) for eye care based on harmful blue light emissions. But the organization has developed a new standard that, among other things, rates each monitor according to the degree of protection it achieves, and the Dell UltraSharp 40 Curved Thunderbolt Hub is the first to receive five stars.
But it took a lot of work from Dell, which increased the refresh rate to 120Hz and integrated ambient lighting and color temperature sensors, ComfortView Plus technology and advanced LED backlighting. The result is smoother images and colors that automatically adjust to ambient conditions, resulting in 17% less eye strain and 35% less exposure to harmful blue light (compared to 50% in previous Dell models).
The above may give the impression that Dell was only interested in eye care, but its screen succeeds in the technical field as well. It offers 99% DCI-P3 and Display P3 color space coverage, has IPS Black Panel technology for 2000:1 contrast and is VESA DisplayHDR 600 certified. It supports Thunderbolt 4 for 140W charging and Ethernet for connections up to 2.5 Gbps and is equipped with two From HDMI 2.1, DisplayPort 2.1, USB Type-A and Type-C ports (even on the front for easier connections).
We note here that on the occasion of the CES exhibition, Dell announced a smaller version of the 34-inch UltraSharp Curved Thunderbolt Hub – which is also curved, with the main difference between the two being in the resolution (the smaller one offers WQHD with a resolution of 2560 x 1440 pixels). The UltraSharp 34 and UltraSharp 40 will be available in February with prices starting at $1,020 and $2,400, respectively, for the US market.
