To update the software, go to Settings > Support > Software Update > Update Now. If an update is available, it will download and install automatically. Ensure your TV is connected to the internet for this process.

To enable HDR, press the Home button, go to Settings > Picture > Expert Settings, and turn on HDR+ Mode. Ensure you are using an HDR-compatible source and HDMI cable.
Turn off the TV and unplug it. Use a microfiber cloth slightly dampened with water to gently wipe the screen. Avoid using chemical cleaners or spraying liquid directly on the screen.
Restart your router and TV. Ensure the TV is within range of the Wi-Fi signal. Check if other devices can connect to the network. If problems persist, try resetting the network settings on the TV and reconnecting.
Press the Home button on your remote to access the Smart Hub. From there, you can navigate through apps, settings, and other features available on your TV.
Refer to the user manual for wall-mounting instructions. Use a VESA-compatible wall mount, ensuring it supports the TV's weight and size. Follow the mount manufacturer's instructions and use appropriate anchors for your wall type.
