LG 4K Ultra HD Smart TV - 55 inch - UA73 Series - Black

4K Ultra HD (UHD) resolution refers to a display that has 3840 pixels horizontally and 2160 pixels vertically, totaling approximately 8.3 million pixels. This is four times the resolution of standard Full HD (1080p), resulting in a much sharper, more detailed, and immersive picture.

Go to the TV's 'Settings' menu, navigate to 'Network', and then select 'Wi-Fi Connection'. Your TV will scan for available networks. Select your home Wi-Fi network from the list, enter your password using the on-screen keyboard, and confirm. Once connected, you'll have access to all smart features and apps.

Yes, this LG 55-inch TV is VESA compliant, meaning it can be mounted to a wall using a compatible wall-mount bracket. You will need to purchase a VESA-compatible mount separately. Always refer to the TV's user manual for specific VESA dimensions and weight limits.

LG Smart TVs typically come with pre-installed popular streaming apps like Netflix, Disney+, YouTube, Amazon Prime Video, and more. You can also download additional apps from the LG Content Store directly on your TV, depending on regional availability and service subscriptions.

To clean the screen, first turn off the TV and allow it to cool. Use a clean, soft, dry microfiber cloth to gently wipe away dust and fingerprints. For stubborn marks, lightly dampen the microfiber cloth with distilled water or a specific TV screen cleaning solution. Never spray liquid directly onto the screen.
