LG OLED B46 55" 4K Smart TV vs LG B6 OLED 48-Inch 4K Smart TV

Both are LG OLED sets with 120 Hz panels, four HDMI ports and the same self-lit picture strengths: perfect blacks, wide viewing angles and no backlight bloom. The B46 is sold in 55, 65, 77 and 83 inches, so it is the one to pick if you want a big screen; the B6 is a 48-inch 2026 model with the α8 AI processor, Dolby Vision, Filmmaker Mode and a built-in DVB-T2/C/S2 tuner. Owners of LG B-series sets praise the contrast and gaming response and accept modest peak brightness and some risk of burn-in with static content.

• Choose the B46 if you want a large OLED screen, up to 83 inches, and a flat 4K 120 Hz panel with four HDMI ports.
• Choose the B6 if you need a compact 48-inch OLED for a bedroom, apartment or desk setup and want the newer α8 processor, Dolby Vision and a built-in Freeview HD tuner.
