Thunderbolt™ 3
The Samsung LC34J791WTWXXL 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.

86.4 cm (34″) Ultra-Wide Screen
The 86.4 cm (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 Color
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 colors for clearer, more vibrant images.

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

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.
