LG G5 Series OLED evo 4K TV (55") vs LG C6 Series OLED 4K Smart TV

Both are LG OLEDs with perfect blacks and wide viewing angles, so the real choice is size and speed versus brightness and processing. The G5 is the gaming pick: a 55-inch panel with a 165Hz refresh rate, four HDMI ports, Wi-Fi 6E and a strong anti-glare coating. The C6 is the big-room pick: the 77-inch version gives a far larger picture, a brighter evo panel with the Alpha 11 Gen3 processor, and Dolby Vision and Dolby Atmos. Owners of both praise OLED contrast; the G5 suits a bright, reflective room at close range, while the C6 suits a dedicated movie room where size matters most.

• Choose the LG G5 if you sit close, play fast games, and want the highest refresh rate and the most HDMI inputs in a 55-inch OLED.
• Choose the LG C6 if you want a much larger 77-inch picture with a brighter evo panel and top-tier processing for movies and sports.
