    Give your visuals power

    More screen to captivate you: Stay on task with immersive productivity on the world’s first 40-inch curved ultrawide WUHD 5K2K monitor.i 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.

    Consistent, vibrant colors: Expect consistent color and picture quality across a wide viewing angle, with IPS technology.

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.
