Unboxing: Carefully remove the TV from its packaging. It's recommended to have two people for this.
Stand Attachment/Wall Mount: Attach the included stand according to the instructions, or if wall mounting, secure a compatible VESA mount (VESA 300 x 300 mm) to the TV and wall. Ensure proper ventilation space around the TV.
Connections: Connect your power cable, then plug in any HDMI devices (e.g., Blu-ray player, game console), antenna, or sound system. The A90K typically features multiple HDMI 2.1 ports for future-proof connectivity.
First Power On: Follow the on-screen guide to set up Google TV, connect to your Wi-Fi network, log into your Google account, and perform initial channel scans.
HDMI Devices: Compatible with a wide range of HDMI devices, including game consoles, soundbars, and media players.
Google TV Ecosystem: Works seamlessly with Google services, including Google Assistant for voice control, Chromecast built-in for casting content from mobile devices, and a vast array of Android apps.
Audio Systems: Supports ARC/eARC via HDMI for easy connection to compatible soundbars and AV receivers.
Screen Cleaning: Use a soft, dry microfiber cloth to gently wipe the screen. For stubborn marks, lightly dampen the cloth with water (do NOT spray water directly on the screen). Avoid harsh chemicals or abrasive cleaners, as they can damage the OLED panel.
Ventilation: Ensure the TV's vents are not blocked to prevent overheating. Maintain adequate space around the TV.
Image Retention Prevention: While OLED technology has advanced, to prevent potential temporary image retention, avoid displaying static images, logos, or user interfaces for extremely long periods. Utilize the TV's screen saver and pixel shifting features (usually enabled by default).
