  • The LG OLED55B9 is the entry-level 4K OLED TV in the company's line-up, and will be released later in the year. The B9 uses the same panel as the 2018 models but adds a new filter; however unlike the C9, E9, and W9 the B9 uses the Alpha 7 Gen 2 processor.

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

    The 55B9 includes HDMI 2.1 connections, allowing 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 the B9 a great choice for gamers. In fact about the only feature the current LG line-up doesn't support is HDR10+.

    The Alpha 7 Gen 2 processor includes OLED Motion Pro, and the upgraded black frame insertion now operates at 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 55B9 will be available in the summer.
