LG C5 77-inch OLED evo 4K Smart TV vs LG OLED55C66LB OLED evo C6 55" TV

The C5 is the one to buy if you want a big, bright OLED for a main room: 77 inches, a 144Hz panel, four HDMI 2.1 ports and Wi-Fi 6E. The C6 is the better fit for a smaller room or a second TV: 55 inches, the newer Alpha 11 Gen3 processor, webOS 26 and a 2.2-channel 40W speaker system. Reviewers and owners rate both lines highly for contrast and gaming; the C6 has the newer chip and platform, while the C5 wins on size and refresh rate.

• Choose the LG C5 if you sit far from the screen, want a 77-inch image for films and sport, and need 144Hz and four HDMI 2.1 ports for consoles and a PC.
• Choose the LG C6 if your room is small or you want the newest processor and webOS 26, and 55 inches is enough for your seating distance.
