The Curve Champion
The leader in curved monitors. Samsung has led the curved monitor market since being the first to introduce the innovative displays to the world in 2015. With industry-leading technology in a full line-up, Samsung’s curved monitors are consistently number one in market share and consumer choice.
Feel the Thunder
Transmit data at speeds of up to 49Gbps — up to 8 times faster than USB 3.0 — with two Thunderbolt™ 3 ports. DP, HDMI, and USB inputs bring varied connectivity for PCs, consoles, and external devices. The built-in 7-watt stereo speakers enhance movie-watching and gameplay.
Curved for comfort
The curved screen is engineered to follow the natural curve of your eyes for a more immersive and comfortable viewing experience. Studies by Harvard Medical School and Seoul National University Hospital found the screen reduced eyestrain in users compared to flat screens and less curved monitors.
Ultra-wide screen
The 34’’ ultra-wide curved display with its 21:9 aspect ratio provides all the workspace you need to multi-task efficiently and in comfort. Forget about inconvenient dual monitor set ups and experience truly seamless multitasking on a single screen.
QLED
Supporting up to 125% sRGB color space, Quantum Dot technology delivers not only more hues than conventional monitors but also colors that are brighter, crisper, and more natural — especially reds and greens. And every monitor is factory calibrated to ensure the most accurate and life-like images
PBP and PIP
Picture-by-Picture (PBP) lets you display to two sources onscreen at their native resolution. And for optimal multi-tasking, with Picture-in-Picture (PIP) you can resize the second source to up to 25% of the screen and position it anywhere.
Fine control
AMD freeSync and 100hz screen refresh rate maximize productivity when working with photo and video files, ensure smoother display and playback, and provide fine cursor control for accuracy. With the CJ79, you can handle even the most demanding tasks with ease.
