Our take on the LG B3 Series 4K UHD OLED Smart TV 55-inch

The LG B3 is LG's entry-level OLED, a 4K panel with 120 Hz refresh, four HDMI ports and support for Dolby Vision and Dolby Atmos. It uses the same self-lit OLED panel technology as LG's pricier C-series, so it delivers perfect blacks, wide viewing angles and near-instant response, but it runs a dimmer panel and an older processor than the C3. It suits movie watchers and console gamers who want true OLED contrast without stepping up to the brighter C-series. Reviewers rate its picture and gaming features highly and call it one of the best-value OLEDs, while noting it struggles in bright rooms compared with brighter rivals.

Questions and answers

Is the B3 worth it over the C3?
The C3 is brighter and has a better processor, which shows in upscaling and HDR highlights. If you watch mostly in a dim room and want to spend less, the B3 gets you the same OLED contrast for less.
Is the B3 good for PS5 and Xbox Series X?
Yes. It has 120 Hz refresh, low input lag and two HDMI 2.1 ports, so it supports 4K at 120 fps and variable refresh rate on current consoles.
How bright is the B3?
It is dimmer than the C3 and much dimmer than bright LCD sets. It looks best in a controlled-light room and can wash out near a sunny window.
Does the B3 support Dolby Vision and Dolby Atmos?
Yes, it supports both Dolby Vision HDR and Dolby Atmos passthrough, so it pairs well with a soundbar or AV receiver.
What sizes does the B3 come in?
LG sells the B3 in 55, 65 and 77 inches. The panel and features are the same across sizes.
Can the B3 get burn-in?
OLED panels can develop permanent marks from static content over long periods. Vary content and use the screen's pixel-refresh and logo-dimming features to lower the risk.
