• No Display: Check all cable connections (power, HDMI/DisplayPort/USB-C) and ensure the monitor is powered on. Verify the correct input source is selected in the OSD menu.
• Flickering/Distorted Image: Check cable connections. Ensure your graphics card drivers are up to date. Adjust resolution and refresh rate settings.
• Monitor Wobble: Ensure the stand is securely assembled and placed on a stable surface.
