About this product
Thunderbolt™ 3 World’s First Thunderbolt 3 Curved Monitor 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. 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 experience when viewing videos and playing games.
