Ranked #3 in Best OLED TVs
LG C5 Series
8 sources1 derived$2,300as of Sep 4

The LG C5 OLED offers exceptional picture quality with deep contrast and accurate colors, making it ideal for movie watching and gaming. It features a sleek, thin design with the Alpha 9 AI processor and supports HDR formats including Dolby Vision. While it provides excellent performance, the remote control has become more difficult to use and the AI assistant lacks compelling features. The C5 is best suited for those seeking high-end OLED performance, though buyers may want to consider the more affordable C4 model for better value.

Strengths
  • — Excellent overall image quality with deep contrast and accurate color reproduction
  • — Great for gaming with support for HDR formats and up to 144 hertz motion rates
  • — Very thin profile at 0.25-inch with a textured black marble back design

  • — AI Assistant feature is not compelling
  • — Price is higher than previous generation C4 model

LG C6 OLED
7 sources$1,499.99as of Sep 4

The LG C6 OLED offers improved brightness and processing power with its Alpha 11 AI Gen 3 chip, delivering vibrant HDR performance even with curtains open. While it outperforms many competing mid-range OLEDs and RGB mini LED models, the 2026 model lineup now splits by panel type, with smaller sizes using the OLED EX three-stack panel. New webOS issues and purchase terms have emerged as notable drawbacks for buyers.

Strengths
  • — 40% brighter SDR and HDR performance compared to previous C5 model with similar panel
  • — Alpha 11 AI Gen 3 processor delivers 6nm efficiency, cooler operation, and 12-bit color processing
  • — Outperforms many RGB mini LED models and rival mid-range OLEDs in picture quality
Watch-outs
  • — Split model lineup with different panels based on size
  • — The performance gap doesn't justify the higher price compared to last year's model.

How they stack up

LG C5 Series

The LG C5 Series offers a very thin profile and AI-powered processing, outperforming the S90H OLED in design and upscaling, but it's less bright than the LG G5 OLED and lacks the superior anti-glare coating of the Samsung S95F Series. Unlike the Sony Bravia 8 II Series, it doesn't feature QD-OLED technology for native 120Hz support.

LG C6 OLED

The LG C6 OLED offers improved brightness and AI processing over the C5 Series, but it's less bright than the LG G5 OLED and lacks the superior anti-glare coating of the Samsung S95F Series. While it's more affordable than the S90H OLED, it doesn't feature the 165Hz refresh rate that makes the S90H better for gaming.
