Work with focus thanks to immersive productivity on the world's first curved, ultra-wide WUHD 5K2K 40" monitor. With 35% more screen space than a 32" 4K, 16:9 display, you can view all your tasks at once.
The curved 2500R screen provides a wider field of view, minimizes reflections, and offers near-uniform visual focus for comfortable all-around viewing. This extra screen real estate lets you see even the smallest details thanks to a 5120 x 2160 resolution and 140 ppi pixel density.
Expect consistent color and image quality across a wide viewing angle thanks to IPS technology. Enjoy lifelike colors with an incredible 1.07 billion color depth and wide color coverage of various industry standards, including 100% sRGB, 100% Rec. 709, and 98% DCI-P3. DCI-P3, with nearly 25% more coverage than sRGB, enables a wider color spectrum and is quickly becoming the color standard for creating and displaying content.
Two integrated 9W speakers provide a high-quality audio experience that immerses you deeper into your work. Connectivity for more productivity: with Thunderbolt 3 and RJ45, this monitor acts as a productivity hub with stable Ethernet connectivity and power, all in a cable-free configuration.
Thunderbolt 3 offers speeds of up to 40 Gbit/s and provides a compact connection that does it all—the fastest and most versatile connection to any docking station, display, or data peripheral.
With comprehensive connectivity options, including Thunderbolt 3, DP1.4, HDMI, USB-C, and ultra-fast USB at 10 Gbit/s, you can connect a wide range of devices. In addition, the convenient USB-C and ultra-fast USB ports on the front let you quickly connect peripherals, such as storage devices and cell phones, and take advantage of the up to 15W charging capability via USB-C.
