Thunderbolt™ 3

The CJ79 series features two Thunderbolt™ 3 ports to connect compatible Macs and PCs. Thunderbolt™ 3 transmits video and data at speeds of up to 40Gbps, that's 8 times faster than USB 3.0 — and can even simultaneously charge devices (up to 85W), all over a single cable.

Curved for comfort

The curved screen is engineered to follow the natural curve of your eyes for a more immersive and comfortable viewing experience.

34” 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.


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.

Quantum Dot Colour

Supporting up to 125% sRGB colour space, Quantum Dot technology delivers not only more hues than conventional monitors but also colours 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.

3000:1 Contrast ratio

Samsung’s VA panel technology provides a 3000:1 contrast ratio that delivers deeper blacks, brilliant whites, and richer colours for clearer, more vibrant images.

AMD FreeSync

AMD FreeSync synchronizes the refresh rates of your graphics card and the CJ79 to minimise image tearing and stutter. The smoother transition between image frames provides seamless gameplay and video playback for uninterrupted viewing.

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.

Stylish Design

With its curved screen bezel-less on three sides for enhanced viewing and its rear panel — finished in glossy white and curving horizontally and vertically — neatly concealing cables, the CJ79’s slim and striking profile is the perfect complement to any Thunderbolt™ 3 Mac or PC.

Multiple inputs

Two Thunderbolt™ 3 ports as well as, DP, HDMI and USB inputs, the CJ79 provide multiple connection options for PCs, consoles, and external devices. And the built-in 7-watt stereo speakers offer an enhanced entertainment experiences when viewing videos and playing games.
