Curved Screen
21:9 Ultrawide Screen
Quantum Dot

Connect to infinite possibilities

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.

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.

Quantum Dot colour

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

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 movie and game scenes.

AMD FreeSync

AMD FreeSync synchronises 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.

Stylish design

With its curved screen bezeless 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.

Stylish design

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.
