LG OLED B4 Series 4K Smart TV vs LG OLED42C6PUA 42" OLED TV

Buy the B4 in 55 inches if you want the bigger screen and the brighter OLED evo panel; the C6 is the better pick only if a 42-inch set fits your room and you want the higher 165Hz refresh rate. The B4 runs LG's α8 processor with four HDMI 2.1 ports, G-Sync, FreeSync Premium and a 0.1ms response, so it suits console and PC gaming as well as movies. The C6 is a smaller C-series panel with Dolby Vision and Atmos, but its listed Wi-Fi 5 and 42-inch size limit it as a main living-room TV. Owners of both lines praise the per-pixel contrast and wide viewing angles; the common complaints are OLED brightness in bright rooms and the risk of burn-in with static content.

• Choose the LG B4 if you want a 55-inch or larger OLED with four HDMI 2.1 ports, G-Sync and FreeSync Premium for gaming and a bright OLED evo panel for movies.
• Choose the LG C6 if your room only fits a 42-inch TV and you want a C-series OLED with Dolby Vision, Dolby Atmos and a 165Hz refresh rate.
