Midrange NanoCell

Hop to

The LG 55SM9000 is a new mid-range NanoCell 4K OLED TV that uses an IPS LCD panel with a full array LED backlight and local dimming. As with most of LG's LCD TVs, the SM9000 uses the Alpha 7 Gen 2 processor.

It does however include ThinQ AI smart functions, and High Dynamic Range support (HDR10, Hybrid Log-Gamma, and Dolby Vision with dynamic metadata).

The SM9000 uses HDMI 2.1 connections, which allows the TV to support High Frame Rates (HFR) such as 4K at 120fps.

It also supports Enhanced Audio Return Channel (eARC), allowing the TV to send lossless object-based audio such as Dolby Atmos and DTS:X back via HDMI ARC.

LG has also added support for Variable Refresh Rate (VRR) and Automatic Low Latency Mode (ALLM), which makes this LCD TV a great choice for gamers.

The Alpha 7 Gen 2 processor includes Motion Pro, with upgraded black frame insertion that uses a 100/120Hz for a shorter black frame cycle. This should eliminate flicker and maintain brightness, while LG has also added a separate decontouring control.

The ThinQ AI functions add an audio feature called ‘AI Sound’, which monitors the images on screen and adjusts and enhances the audio based on this. It will also be able to upconvert stereo to 5.1, as well as support Dolby Atmos.

Finally there's a new version (4.5) of webOS with voice assistance that has been expanded to include Amazon Alexa as well as Google Assistant. LG is also adding support for Apple's AirPlay 2 and HomeKit features.

LG hasn't announced any prices yet, but the 55SM9000 will be available in the spring.
