Start by choosing your installation option and ensuring you have a solid, level surface for stand mounting or a compatible wall mount for wall installation. Follow these steps for a clean, secure setup and optimized viewing:

Step 1: Unbox and inspect – Remove the TV from its packaging, locate all included accessories (stand or mounting hardware, power cable, remote, and batteries), and verify that you have the necessary tools for installation. Handle the screen with care and keep the protective film in place until you’re ready to power up to minimize risk of scratches.

Step 2: Choose your mounting method – If you’re using a pedestal stand, attach it according to the included instructions, ensuring it is firmly secured. If mounting on a wall, select a compatible VESA wall mount and confirm weight and dimension tolerances align with the TV’s specifications. Proper mounting not only provides a secure setup but also helps optimize viewing angles and reduce glare.

Step 3: Connect power and devices – Place the TV in its intended position, connect the power cable, and route cables neatly for a clean appearance. Attach HDMI cables to your gaming console, Blu-ray player, or receiver, and connect any external speakers or soundbars you plan to use via the appropriate ports. If you’re using a streaming device or a console, connect it to the TV’s HDMI ports for best results.

Step 4: Configure network connectivity – Turn on the TV and follow the on-screen prompts to connect to your home network. You can choose a wired Ethernet connection for stable streaming or a Wi‑Fi network for flexibility. A Samsung account is recommended to access apps, cloud features, and personalized settings.

Step 5: Calibrate picture and sound – Select your preferred picture mode (Cinema for cinematic viewing, Standard for everyday content, or a custom setting that suits your room lighting). Enable HDR settings for compatible content to maximize contrast and color accuracy. Adjust sound settings to your room acoustics and connect to a Dolby Atmos-enabled system if desired for the fullest audio experience.

Step 6: Update software and personalize – Check for the latest firmware updates to ensure you have the newest features and performance improvements. Sign in to your preferred streaming services, download apps, and customize the home screen with your most-used content for quick access.

Step 7: Optimize for gaming and streaming – If you’re a gamer, explore any game-mode or VRR settings available in the display options to minimize input lag and ensure smooth motion.
