LG OLED55C66LB OLED evo C6 55" TV vs LG OLED evo C4 65-Inch TV

The C6 is the newer set: a 2026 OLED evo panel with the Alpha 11 Gen 3 processor, webOS 26, 40W 2.2 audio and a 165Hz VRR ceiling. The C4 is a 65-inch 2024 model with the older Alpha 9 Gen 7 chip, up to 144Hz and a strong 4.6-out-of-5 owner score across 572 ratings. Buy the C6 for the better processor, newer platform and smaller footprint; buy the C4 if the extra 10 inches matter more than a generation of processing. Both are 120Hz OLEDs with four HDMI 2.1 ports, Dolby Vision and Dolby Atmos, so the gap is refinement and size, not core picture technology.

• Choose the LG C6 if you sit close, have a smaller wall or want the newest processor, webOS 26 and the higher 165Hz VRR ceiling.
• Choose the LG C4 if you want the bigger 65-inch picture and a proven set with a long record of owner ratings.
