• Refresh Rate: 120 Hz
• Response Time: 0.1 ms
• Aspect Ratio: 16:9
• Viewing Angle: 178 degrees
• HDR Support: Dolby Vision IQ, Cinema HDR, and HDR 10

The inclusion of Dolby Vision IQ is a critical architectural feature, as it allows the TV to adjust picture settings based on the ambient lighting conditions of the room, ensuring that the AI brightness optimization maintains visual integrity regardless of the environment.

The inclusion of User Profiles allows different members of a household to have personalized content recommendations and settings.

Cinematic and Gaming Performance

For movie lovers, the Filmmaker Mode is a standout feature, allowing the display to show content exactly as the director intended by minimizing unnecessary post-processing. This is complemented by the Dolby Atmos audio support, which provides a multi-dimensional soundstage. The AI Sound Pro feature further enhances this by providing a Virtual Surround 5.1.2 up-mix, creating a more immersive auditory environment from the built-in 20-watt, 2.0 Ch speaker system.

Gamers will find the Game Optimizer mode essential. The combination of a 120 Hz refresh rate and an incredibly fast 0.1 ms response time ensures that motion blur is virtually non-existent, providing a competitive edge in fast-paced titles. The 4 HDMI ports allow for the simultaneous connection of a set-top box, Blu-ray player, and multiple gaming consoles without the need for constant cable swapping.

Smart Integration and Control

The usability of the device is enhanced by its deep integration with the modern smart home ecosystem. With Built-in Alexa and Google Assistant, users can control the TV and other connected devices via voice commands. Furthermore, the support for Apple Airplay 2 & Homekit makes it an ideal choice for iPhone and Mac users who wish to cast content or control their home environment directly from their mobile devices. The remote control utilizes Bluetooth technology, ensuring a reliable connection without the need for direct line-of-sight required by traditional infrared remotes.

Design, Build Quality & Efficiency

The LG 55B2PSA features a sleek, modern aesthetic in a Black finish, designed to blend into contemporary interior decors. The physical dimensions of the unit are 4.69 x 122.8 x 70.8 cm, with a total weight of 18.9 kg (noted as 18 kg 900 g in specific metrics), making it a substantial yet manageable piece of hardware for wall mount installation or tabletop placement.

The build quality is consistent with LG's premium OLED lineup, prioritizing a slim profile that maximizes the screen-to-body ratio. In terms of power consumption, the device operates on a standard 240V AC power source with a rated wattage of 335 watts.
