55-inch OLED TV with 165Hz refresh

This 55-inch OLED TV delivers 4K resolution at a 165Hz refresh rate and is powered by the NQ4 AI Gen3 Processor with 128 neural networks. It targets viewers who want self-illuminating pixels, wide viewing angles, and AI-enhanced picture quality for streaming, sports, and gaming in a graphite-black design.

Check HDMI ports and network before buying

Verify that your source devices can output 4K at high frame rates over HDMI and that you have a Wi-Fi 6E router or wired Ethernet for the smart platform. The set includes four HDMI inputs and built-in wireless, so confirm your cables and home network support the bandwidth you plan to use.

Screen cleaner and protection plan included

A 6.8oz ammonia-free screen cleaning spray and a two-year Amber protection plan ship with the TV. The cleaner removes dust, dirt, and fingerprints without damaging the OLED panel, while the plan extends coverage beyond the standard manufacturer warranty for added peace of mind.
