How to use

Connect the monitor to your PC or console using DisplayPort 1.4 for maximum refresh performance on PC or HDMI for console connections. Use the on-screen display (OSD) menu to select the desired picture mode, enable adaptive sync (FreeSync/G-SYNC Compatible) and configure HDR when supported by the source. If using multiple systems, set up the KVM feature and connect keyboard and mouse to the monitor's USB hub to switch control between inputs. Adjust tilt, swivel, pivot and height to achieve an ergonomic viewing position.

Recommendations

For competitive gaming, use DisplayPort with a capable GPU and set the monitor to 300 Hz (or OC 320 Hz if your GPU supports it) and 1 ms response mode. Enable adaptive sync to reduce screen tearing. For console use, connect via HDMI and verify the console output settings to benefit from 4K/120Hz when applicable. Ensure the monitor firmware and GPU drivers are up to date for optimal compatibility and performance.
