Debuting at CES 2021 and receiving an Innovation Award there, the Dell UltraSharp 40 (U4021Q) claimed the spot of the world’s first 40-inch ultrawide curved monitor with a 5120×2160 resolution, also known as 5K2K or WUHD.
With a 21:9 aspect ratio, the UltraSharp 40 is designed for users who want lots of screen real estate within a single display, but without compromising on resolution. A built-in Thunderbolt 3 port allows the UltraSharp 40 to be connected to a compatible Mac with a single cable; the monitor can power a MacBook Pro with up to 90W of passthrough charging.
Additional IO includes two HDMI 2.0 ports, a DisplayPort 1.4 port, three 10Gbps USB-A ports, one USB Type-B upstream port, an Ethernet port, and a 3.5mm headphone/audio jack on the back of the monitor, plus one 15W USB-C port and another 10Gbps USB-A port on the bottom of the monitor for quick access. The UltraSharp 40 is 10-bit and covers 100% of the sRGB and 98% of the DCI-P3 color spaces, producing 1.07 billion colors. Other specs include a fast 5ms response time, a 60Hz refresh rate, 2500R curvature, built-in KVM functionality, and integrated 9W speakers. A picture-in-picture mode allows the UltraSharp 40 to mimic two displays side by side, and “ComfortView Plus” feature reduces blue light.
