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

Samsung S90H OLED
Ranked #8 in Best OLED TVs
Samsung S90H OLED
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 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.

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.
