LG C6 OLED

4.6

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.

Ranked #8 in Best OLED TVs

Samsung S90H OLED

4.1

5 sources1 derived$1,097.99as of Sep 4

The Samsung S90H OLED offers flagship OLED performance at a more accessible price point, making it a strong recommendation for those seeking premium picture quality without Dolby Vision support. It features a brighter WOLED panel, 165Hz refresh rate borrowed from the S95F, and Samsung's NQ4 AI Gen3 Processor for smooth navigation and upscaling. While praised for its sleek design and easy setup, reviewers noted the high price and somewhat cheap-feeling pedestal stand cover as drawbacks. This TV is ideal for gamers and movie enthusiasts who want top-tier OLED performance but may not suit budget-conscious buyers or those seeking the absolute latest in display technology.

Strengths

— Brighter, more refined WOLED panel with improved brightness
— 165Hz refresh rate for smooth gaming and motion
— Easy setup with tool-free dual feet and intuitive SmartThings app

Watch-outs

— High price point at $1,699 for the 55-inch model
— Anti-glare matte finish may not appeal to all users

How they stack up

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.

Samsung S90H OLED

The Samsung S90H OLED provides a more affordable flagship experience with 165Hz refresh rate and WOLED brightness, outperforming the S90F in motion handling, but it lacks the anti-glare coating of the S95F Series and the HDR accuracy of the LG G5 OLED. Compared to the Sony Bravia 8 II Series, it doesn't feature QD-OLED technology for native 120Hz support.
