CES 2021: Dell launches 40-inch 5K2K ultra-wide monitor with Thunderbolt 3 connectivity for Mac



Dell launched a series of new monitors this week, one of which is particularly suitable for Mac users: UltraSharp 40 Curved WUHD Monitor.

UltraSharp 40 or “U4021QW” is the winner of the CES 2021 Innovation Award. It is the world’s first 40-inch ultra-wide curved display with a resolution of 5120×2160, also known as 5K2K or WUHD. This is not a true 5K resolution, but can reach about 140 PPI, which is equivalent to a 32-inch 4K display, but the visible space has increased by 33%.

UltraSharp 40 has an aspect ratio of 21:9, which is very suitable for users who want to fit a large amount of screen space in a single display without affecting the resolution. In addition to the ultra-wide 34-inch 5K2K display launched by LG since 2018, UltraSharp 40 is one of the only ultra-wide displays with Retina quality, most of which have a lower QHD resolution of 2560×1440.

The built-in Thunderbolt 3 port can connect the UltraSharp 40 to a compatible Mac with a single cable, and the display can power the MacBook Pro with up to 90W pass-through charging. Other connectivity includes two HDMI 2.0 ports, a DisplayPort 1.4 port, three 10Gbps USB-A ports, a USB type B upstream port, an Ethernet port and a 3.5mm headphone/audio jack on the back of the monitor, and a 15W USB -C port and another 10Gbps USB-A port at the bottom of the display for quick access.

Dell said that UltraSharp 40 is a 10-bit display that can cover 100% of sRGB and 98% of DCI-P3 color space, and can produce 1.07 billion colors. However, for high-end displays, the peak brightness is relatively low at 300 nits. Other specifications include a fast response time of 5ms, a refresh rate of 60Hz, a curvature of 2500R, a built-in KVM function and an integrated 9W speaker. Dell did not indicate whether there is HDR support, so it should not be expected.

UltraSharp 40 is suitable for content creators, creative professionals, data analysts and coders. In the picture-in-picture mode, UltraSharp 40 can simulate two displays side by side, and the so-called “ComfortView Plus” function can reduce blue light.

Dell said the UltraSharp 40 will be available on January 28, with a starting price of $2,099.99 in the United States.
