A dedicated hotkey makes switching between modes fast and convenient.
With an extraordinary 0.02ms GtG response time, the OLED panel delivers near-instantaneous pixel transitions to help minimize motion blur and ghosting.
Combined with refresh rates reaching 720Hz, it provides exceptional motion clarity for competitive FPS, esports, racing, and other fast-paced games.
Experience exceptional HDR contrast with VESA DisplayHDR™ True Black 500. OLED technology produces deep blacks and detailed shadows, helping reveal subtle details in dark gaming environments.
A contrast ratio of approximately 1,500,000:1 provides outstanding separation between bright highlights and deep blacks.
The monitor covers up to 99.5% (Typ.) of the DCI-P3 color gamut, delivering rich and vibrant colors across games and multimedia content.
With Delta E ≤ 2 color accuracy, the display is also well suited to creators who require precise and consistent color reproduction.
UL verification reinforces the OLED panel’s ability to produce deep blacks and faithfully reproduce visual content, helping maintain intended colors and details across both bright and dark scenes.
DisplayPort 2.1 provides the high bandwidth required for next-generation high-refresh-rate gaming, enabling the monitor to take full advantage of its extreme performance capabilities with compatible hardware.
The monitor also features dual HDMI 2.1 ports, providing flexible connectivity for gaming PCs and modern consoles.
Built-in USB-C connectivity helps simplify your desktop setup with a versatile single-cable connection for compatible devices, making the monitor suitable for both high-performance gaming and modern workstation environments.
Support for NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro helps synchronize the display with compatible graphics hardware, reducing screen tearing and stuttering while maintaining smooth, low-latency gameplay at high refresh rates.
The matte screen surface helps reduce reflections and distracting glare, providing improved visibility and a more comfortable experience during extended gaming sessions.
