Redefine productivity on this revolutionary 40” curved WUHD 5K2K monitor that delivers exceptional color and clarity.

More screen to captivate you: Stay on task with immersive productivity on the world’s first 40-inch curved ultrawide WUHD 5K2K monitor. With 35% more onscreen space than a 32-inch 4K 16:9 screen, you have room to view all of your work at once.

A view that draws you in: The 2500R curved screen creates a wider field of view, minimizes reflection and offers near uniform visual focus, for a comfortable, panoramic, wrap-around view.

Unmatched clarity: Across that additional screen space, you’ll see fine, intricate details with ultra high 5120 x 2160 resolution and a 140 ppi pixel density.

Consistent, vibrant colors: Expect consistent color and picture quality across a wide viewing angle, with IPS technology. See true-to-life color with an incredible color depth of 1.07 billion colors and wide color coverage across industry standards, including 100% sRGB, 100% Rec. 709 and 98% DCI-P3. DCI-P3 (which offers nearly 25% more coverage than sRGB), enables a wider range of colors and is quickly becoming the color standard for creating and viewing content.

All-encompassing sound: Integrated dual 9W speakers deliver quality sound for an auditory experience that pulls you in even further.
