Description
Deeper blacks and richer detail with VA panel
The VA panel offers exceptional contrast and deep blacks, revealing every nuance between light and dark.

Whether watching movies, editing content, or gaming, benefit from consistent picture quality and wide viewing angles that bring every detail to life.
Easy multi-device control with KVM
Easily switch between multiple computers using one monitor, keyboard, and mouse, making multitasking smooth and efficient.
Built-in audio without extra clutter
Enjoy clear, pleasant sound for calls, videos, and music while keeping your desk free of extra speakers, thanks to the integrated audio.

Dual Mode empowers your workflow by offering crystal-clear 4K resolution for precise data work, or a responsive 120Hz Full HD setting for smooth motion during live feeds and dynamic content.
