Our take on the LG 55" B5 Series 4K Ultra HDR Smart OLED AI WebOS TV w/ Dolby Atmos

The LG B5 is LG's entry-level OLED, a 55-inch 4K smart TV with self-lit pixels, Dolby Atmos and the webOS platform with AI features. It delivers the deep blacks and wide viewing angles OLED is known for, at a step below LG's brighter C-series. It suits movie and streaming fans in a normal-lit room who want OLED contrast without paying for the step-up models. Reviewers rate its picture and gaming features highly but note it is dimmer than the C-series and less suited to very bright rooms.

Questions and answers

How does the B5 compare with LG's C-series?
The B5 uses a similar OLED panel but has lower peak brightness and a less advanced processor. The C-series is the better pick for bright rooms; the B5 covers dark-room movie and gaming use well.
Is it good for gaming?
Yes. It has HDMI 2.1 ports with variable refresh rate and high frame rate support, plus low input lag in game mode. It is a solid match for current consoles.
Is OLED burn-in a concern?
OLED can retain static images over long periods. Vary content, avoid leaving news tickers or game HUDs on for hours, and use the TV's screen-care features.
Does it support Dolby Vision and Dolby Atmos?
Yes, both are supported. Atmos works best with a soundbar or AV receiver, since the built-in speakers are limited.
What is in the box?
The TV, its stand, a remote and the power cable. A wall mount and HDMI cables are not included.
Is it bright enough for a sunny room?
It is best in a room where you can control the light. In a very bright room, reflections and lower brightness make it less ideal than a brighter LED or the C-series.
