How to use

Connect the monitor to your PC or console using DisplayPort or an HDMI 2.1 cable to enable high refresh rates and full bandwidth features. Adjust the monitor height and tilt for ergonomic viewing. Use the on-screen display (OSD) menu to select preferred picture modes, refresh rate, and any adaptive sync or VRR settings. Enable OLED Care 2.0 and other panel-protection features in the OSD to reduce the risk of image retention.

Recommendations

For longevity and consistent image quality, vary static content on-screen, avoid leaving high-contrast static images for extended periods, and enable the built-in OLED Care features. When using consoles, use HDMI 2.1 cables rated for 48 Gbps to ensure full compatibility with 120 Hz and VRR modes.
