LG 83" C6 Series 4K OLED TV vs LG C5 Series OLED evo 4K Smart TV

Both are 83-inch LG OLED evo sets with four HDMI 2.1 ports, Dolby Vision, Dolby Atmos and 120Hz panels, so the picture and gaming basics are close. The C6 is the newer 2026 model: a brighter OLED evo panel, the Alpha 11 Gen3 processor, VRR up to 165Hz and webOS 26. The C5 is the 2025 model with the Alpha 9 Gen8 chip and webOS 25. Owners and reviewers rate the C-series highly for contrast and gaming; the C6 is the step up if you want the brightest panel and the fastest VRR, while the C5 covers the same ground for less.

• Choose the LG C6 if you want the brightest 83-inch OLED LG makes, 165Hz VRR for PC gaming and the newest webOS 26 features.
• Choose the LG C5 if you want the same 83-inch OLED evo picture, four HDMI 2.1 ports and Dolby Vision for less than the newest model.
