  • Dell announced the UltraSharp 40 Curved WUHD Monitor at CES 2021.
  • It's the world's first 40-inch ultrawide with a 5K2K resolution, according to Dell.
  • The Dell UltraSharp 40 starts shipping on January 28 for $2,100.

Dell announced a 40-inch ultrawide curved monitor as part of CES 2021, the Dell UltraSharp 40 Curved WUHD Monitor. According to Dell, it's the world's first 40-inch ultrawide curved WUHD (5K2K) monitor. The UltraSharp 40 won the CES 2021 Innovation Award and will be available on January 28 with a starting price of $2,100.

The monitor has a built-in Thunderbolt 3 port and can power devices with up to 90W of pass-through charging. It also has two HDMI 2.0 ports, a DisplayPort 1.4 port, three 10 Gbps USB-A ports, one USB-B upstream port, an Ethernet port, and a headphone jack. On the bottom of the monitor, there are an additional USB-C port and 10 Gbps USB-A port.

The UltraSharp 40 features a 10-bit display that covers 90 percent of the DCI-P3 color space and 100 percent of the sRGB color space. It has a response time of 5ms and a 60Hz refresh rate.

The UltraSharp 40 has a 2500R curvature, which is more immersive than a flat monitor but isn't as extreme as some other models. For comparison, the Samsung Odyssey G7 and G9 gaming monitors have a curvature of 1000R.

As highlighted by MacRumors, the monitor has a resolution of 5120 x 2160, but it does not have the pixel density of a traditional 5K monitor. The Dell UltraSharp 40 Curved WUHD Monitor is known as a 5K2K monitor and has a pixel density of close to 140 PPI, which is about the same as a 32-inch 4K monitor.

Dell also announced several other monitors ahead of CES 2021. Those monitors feature a dedicated Microsoft Teams button and are built with video conferencing in mind.
