In 2019, LG introduced several models in the NanoCell 8 Series, all featuring 4K resolution, NanoCell technology, and AI-enhanced capabilities. While they share many core features, they differ in backlighting technology, HDR support, processing power, and audio performance.
LG SM8670
The LG SM8670 is the premium model in the series, available in a 75-inch size. It features Nano Color and Nano Accuracy for superior color reproduction. The TV has Edge LED backlighting with Local Dimming, providing better contrast.
It is powered by the α7 Gen 2 Intelligent Processor, which enhances picture quality and overall performance. The Ultra Luminance Pro technology improves brightness, while HDR Dynamic Tone Mapping Pro enhances HDR content. The 40W sound system includes a 20W subwoofer, delivering a more immersive audio experience.
LG SM8610
The LG SM8610 is available in 49″, 55″, 65″, and 75″ sizes. It also features Edge LED backlighting with Local Dimming but lacks Ultra Luminance Pro, resulting in slightly lower brightness than the SM8670. The TV is powered by the α7 Gen 2 Intelligent Processor and supports Dolby Vision, HDR10, and HLG.
LG SM8600
The LG SM8600 is very similar to the SM8610, with the same Nano Color technology, Edge LED backlight with Local Dimming, and α7 Gen 2 Intelligent Processor. However, it includes Ultra Luminance Pro, improving brightness and contrast performance. It also supports HDR Dynamic Tone Mapping Pro for enhanced HDR visuals.
LG SM8500
The LG SM8500 stands out with Slim Direct Backlighting and Full Array Local Dimming (FALD), offering superior contrast compared to models using Edge LED. It features the α7 Gen 2 Intelligent Processor and Ultra Luminance Pro for enhanced brightness. The 40W audio system includes a 20W subwoofer, making it one of the best options for audio performance.
LG SM8200
The LG SM8200 is the entry-level model in the series, featuring NanoCell technology but using a Quad-Core Processor instead of the α7 Gen 2. It lacks Ultra Luminance Pro, Dolby Vision, and a subwoofer, making it a more basic option. The audio output is 20W without additional enhancements.
