LG OLED C5 Series 4K TV vs LG C6 Series OLED 4K Smart TV

Both are 55-inch LG OLEDs with four HDMI 2.1 ports, Dolby Vision and perfect blacks, so the picture fundamentals are close. The C6 is the newer step up: a brighter evo panel with the Alpha 11 Gen3 processor, a 165Hz refresh rate and webOS 26. The C5 is the prior generation, still 144Hz with Dolby Vision and HDR10+, and it is the smarter pick if you want proven last-gen OLED performance. Reviewers consistently praise LG's OLED contrast and viewing angles on both, while noting OLED's brightness ceiling and burn-in risk in bright, static-heavy rooms.

• Choose the LG C5 if you want a well-established 144Hz OLED with HDR10+ support and the same four HDMI 2.1 inputs.
• Choose the LG C6 if you want the brighter evo panel, the newer Alpha 11 Gen3 processor and a 165Hz refresh rate.
