Setup, Compatibility & Care
Ensure your desk is stable and has sufficient depth to accommodate the large 39-inch curved chassis. For the best performance, always use a high-bandwidth DisplayPort or HDMI cable capable of handling the 3440×1440 resolution at 240Hz. To maintain the OLED panel, avoid displaying static images for extended periods to prevent burn-in; use the built-in screen saver and power-saving features. Regularly update your monitor firmware via the webOS interface to ensure the latest AI optimizations and security patches are applied. When cleaning, use only a soft, dry microfiber cloth and avoid harsh chemical cleaners which can strip the protective anti-glare coating.
