How to use

Adjust display settings such as resolution (1920 x 1080), refresh rate (set to 144 Hz in your graphics driver or OS), brightness and colour settings through the monitor on-screen menu and your device's display control panel. For optimal motion performance, enable the higher refresh rate in system settings and select the fastest response mode if available.
Usage recommendations
For accurate colour work, allow a brief warm-up period after powering on and calibrate the display with a hardware calibrator if precise colour matching is required. Set the refresh rate to 144 Hz in your operating system and graphics driver for the smoothest motion; ensure your GPU and cables support the selected refresh rate and resolution.
