Product details
The CJ791 has two Thunderbolt 3 interfaces to connect to Macs and PCs. Thunderbolt 3 transfers video and data at speeds of up to 40GB per second - eight times faster than USB 3.0 - while charging devices (up to 85W) with just one cable.
The 34" widescreen display with a 21:9 aspect ratio gives you a generous display area so you can multitask comfortably and efficiently. You no longer need two screens while still saving precious desk space.
Quantum Dot technology supports an impressive sRGB color space, delivering not only more hues than conventional monitors, but also brighter, sharper, and more natural colors - especially in reds and greens. Plus, each monitor is factory calibrated to reproduce accurate and lifelike colors.
