Features

Thunderbolt 3 and DaisyChain Connectivity

This business monitor is equipped with two Thunderbolt 3 (TBT3) ports, providing a single cable connection for transmitting digital display, data (USB) and power. Connect your PC or mobile device with the USB-C port for an instant workstation. Plug peripherals in the monitor and work while charging your mobile device at up to 100W. Transfer data at up to 40Gbps and connect up to two monitors or six total devices, daisy chained, through a single compact port.ยน

Ultra-Curved Screen and Seamless Design

Samsung's 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.

Brilliant Color with QLED

This monitor supports up to 125% of the sRGB color space, 95% DCI and 1.07 billion colors thanks to Quantum Dot (QLED) technology. So you get exceptionally bright, crisp and natural reds and greens, plus smooth and seamless color transitions. Plus, every monitor is factory calibrated for color consistency.

Split-Screen (PBP) and Picture-in-Picture (PIP)

Connect up to two separate sources to the display and view them simultaneously with split-screen (PBP) and picture-in-picture (PIP) technology. Perform work, like coding, in one window and see the results in a separate window. With the included Samsung software, you can make window management easy and maximize your efficiency.

Fully Adjustable Stand and VESA Compatibility

The monitor swivels, tilts and is height-adjustable, to deliver comfort and ergonomics at work. And with VESA mount compatibility, installation on a wall or separate mounting arm is easy.

Easy on the Eyes

Eye Saver Mode and Flicker Free technology help to reduce eye strain for a more comfortable work experience, even during long work hours. When Eye Saver Mode is active, blue light levels are lowered. And flicker-free technology eliminates flickering at all levels of brightness.
