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. 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. 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. 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.
