Connect to Infinite Possibilities
Thunderbolt™ 3
The CJ79 features two Thunderbolt 3 ports to connect compatible Macs and PCs. Thunderbolt 3 transmits video and data at speeds of up to 40Gbps — 8 times faster than USB 3.0 — and simultaneously charges 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. 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.
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.
3000:1 Contrast Ratio
Samsung’s VA panel technology provides a 3000:1 contrast ratio that delivers deeper blacks, brilliant whites, and richer colors for clearer, more vibrant images.
Fast 100 Hz Refresh Rate
The fast 100 Hz 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.
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.
