Key Features and Settings
- 180Hz Native Refresh Rate: For smoother motion in fast-paced content. Ensure your graphics card and connection cable support this refresh rate. Adjust in your computer's display settings.
- 1ms GTG Response Time: Minimizes motion blur and ghosting. This setting can often be adjusted in the OSD's "Gaming" section (e.g., Overdrive setting).
- HDR600 Brightness: Provides enhanced contrast and color for HDR content. Enable HDR in your operating system's display settings.
- AMD FreeSync: Synchronizes the monitor's refresh rate with your AMD graphics card's frame rate to eliminate screen tearing and stuttering. Enable FreeSync in the monitor's OSD and your AMD Radeon Software.
- QD-Mini LED & QLED: These technologies enhance color accuracy, brightness, and contrast. These are core display technologies and do not require specific user activation beyond enabling HDR for optimal performance.
- TÜV Low Blue Light Certification: Reduces harmful blue light emissions to minimize eye strain during prolonged use. This mode can typically be activated or adjusted in the OSD menu.
- Crosshair Aim Guide: An on-screen crosshair overlay for gaming. Activate this feature through the OSD menu.
