Detailed Contrast
HDR-compatible monitors display brighter whites and blacker blacks compared to conventional displays. HDR renders dark and bright areas of an image with many more details, which were indiscernible under the old standards.
Unified Interface for Easy Set-up
OnScreen control gives quick, easy access to a host of important monitor settings.
Higher Work Efficiency
With its elegant, stunning profile, this monitor turns heads even when powered off. Its virtually borderless design and gorgeous slim ArcLine stand add to its chic image.
