C34J791 34" Curved Ultra-Wide Monitor with Thunderbolt 3 and Quantum Dot Technology

A gracefully curved, virtually bezel-less ultra-wide monitor featuring Quantum Dot technology for an exceptional picture and Thunderbolt 3 connectivity for multi-purpose connectivity.

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.

With a 1500R curvature, the C34J791 34" 21:9 Curved LCD Monitor from Samsung offers a viewing experience that envelops the viewer in their multimedia content. Flicker-free technology, AMD FreeSync support, Game Mode, and Eye Saver Mode all help to provide a healthy and enjoyable time whether you're writing up a report, playing games, or simply kicking back and watching a movie.

This Samsung monitor features a 3440 x 1440 resolution, a 3,000:1 contrast ratio, a 300 cd/m2 brightness rating, a 100 Hz refresh rate, a 4 ms response time, and support for up to 16.7 million colors all designed to provide a crisp, clear picture with reduced ghosting and blur. Additionally, the C34J791 display offers 178° horizontal and vertical viewing angles along with the ability to tilt the display or mount it to the wall for more comfortable viewing.

Thunderbolt 3 and DaisyChain Connectivity

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.


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.

Fast 100hz Refresh Rate

The fast 100Hz screen refresh rate provides smoother, silkier mouse sensitivity for enhanced productivity in any application. It also reduces screen stutter in fast-moving action scenes for a flawless gaming experience.


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.

3000:1 Static Contrast Ratio

Samsung's advanced VA panel technology minimizes light leakage across the entire screen and corners and delivers a 3000:1 contrast ratio for deep blacks and brilliant whites in even the darkest and brightest scenes.


Smooth Gameplay with AMD FreeSync

By dynamically synching the screen refresh rate with the image frame rate, AMD FreeSync minimizes stutter.
