3. Adjusting Display Settings
- Refresh Rate: The monitor supports an ultrafast 170Hz (overclocked) refresh rate. This can be adjusted in your graphics card settings or through the monitor's OSD.
- Response Time: ASUS FastIPS technology enables a 1ms response time (GTG) for sharp gaming visuals. This setting is crucial for reducing ghosting and motion blur.
- G-SYNC Compatible: This monitor is Certified as G-SYNC Compatible, providing a tear-free gaming experience by enabling Variable Refresh Rate (VRR). Ensure G-SYNC is enabled in your NVIDIA control panel.
- Extreme Low Motion Blur Sync (ELMB SYNC): ELMB SYNC technology works with G-SYNC Compatible to eliminate ghosting and tearing, delivering sharp visuals at high frame rates. Activate this feature through the OSD.
- HDR™ 400: High Dynamic Range (HDR) technology with DCI-P3 95% color gamut and DisplayHDR 400 certification delivers enhanced contrast and color performance. Enable HDR in your operating system display settings for compatible content.
- Eye Care: The monitor incorporates Eye Care features to reduce eye strain during prolonged use. Adjust Blue Light Filter settings via the OSD to minimize harmful blue light emissions.
