The LG B3 is LG's entry-level OLED, sold in 55, 65 and 77 inches. It uses a self-lit OLED panel with 4K resolution and a 120 Hz refresh rate, so contrast is per-pixel and motion is smooth for games and sports. It has four HDMI 2.1 ports with 4K/120 support, VRR and G-Sync/FreeSync compatibility, plus webOS with Google Assistant, Alexa and Siri. It sits below the C3: the B3 uses an older, dimmer panel and a slower processor, so it peaks lower in HDR highlights and upscales less sharply, but it keeps the core OLED strengths at a lower tier. Reviewers rate it highly for picture quality and gaming features and note it is dimmer than the C-series in bright rooms.
