At a Glance
Samsung's CJ791 Series ultra-wide curved monitor delivers an exceptional picture in a sophisticated design. Cutting-edge Quantum Dot (QLED) combined with WQHD resolution deliver vibrant color and fine detail, while the virtually bezel-less frame offers a clean look. And Thunderbolt 3 connectivity adds to that by enabling the transmission of digital display, data (USB) and power through a single cable connection for a clutter-free workspace.

Ultra-Curved Screen and Seamless Design
Samsungs super curved VA panel is designed for comfort, productivity and style. With a 1500mm radius, the distance from screen to eye is a more uniform distance, resulting in less eye fatigue when working long hours. Wide viewing angles help to ensure the picture is not degraded from off angles. Plus, it sits in a sleek and seamless 3-sided virtually bezel-less frame, so you see more picture and less plastic.

Ultra-Wide 21:9 Aspect Ratio and WQHD Resolution
An ultra-wide 21:9 aspect ratio provides more room to work for enhanced productivity. WQHD resolution delivers twice the pixels and detail of Full HD resolution. Combined with a 3:000:1 contrast ratio, you get a vibrant, sharp picture so you never miss a detail.
