Experience vivid visuals on a 27" QHD (2560x1440) IPS display that preserves color accuracy and picture quality even at wide viewing angles. The monitor supports HDR10 for enhanced contrast and up to 99% sRGB color gamut coverage to reproduce richer, more accurate colors for games, movies and creative work while maintaining a slim, virtually borderless three-sided design and an ultra-slim stand to optimize desktop space.

Advantages

The 100Hz refresh rate and 5ms (GTG) response time deliver smoother motion and reduced motion blur for gaming and fast-paced content. USB Type-C connectivity provides one-cable convenience and up to 15W power delivery to charge compatible laptops or connect peripherals. Reader Mode lowers blue light emission to reduce eye fatigue during extended use. Dynamic Action Sync minimizes input lag for near real-time responsiveness, and Black Stabilizer brightens dark scenes for better visibility in shadowed areas. The Switch app enables flexible multitasking with split-screen layouts and quick access to streaming and webOS features.
