Choosing between the LG C3 vs Samsung S90C OLED TVs in 2025 is like deciding between two champions of display innovation. Both models represent the pinnacle of OLED technology, yet they take distinctly different approaches to performance, picture processing, and ecosystem integration.
In this detailed LG C3 vs Samsung S90C comparison, we’ll explore where each TV truly excels—helping you make an informed choice based on your priorities for gaming, home theater, and smart home connectivity.
Display Technology: LG C3 vs Samsung S90C
The LG C3 features LG Display’s traditional White OLED (WOLED) panel, enhanced by the evo layer for improved brightness and efficiency. In contrast, the Samsung S90C utilizes Quantum Dot OLED (QD-OLED) technology, which combines OLED contrast with Quantum Dot color enhancement. This gives it a distinct edge in a few areas:
Higher peak brightness, making highlights pop in HDR scenes.
Wider color gamut, delivering richer and more accurate tones.
Better off-angle viewing, maintaining color consistency from different perspectives.
However, the LG C3 excels in areas where longevity and format support matter most:
Superior burn-in prevention, thanks to LG’s advanced pixel care and compensation algorithms.
Full Dolby Vision compatibility, offering better tone mapping and dynamic HDR support than the S90C.
In summary, when comparing LG C3 vs Samsung S90C, Samsung’s QD-OLED panel offers a slight edge in brightness and color, while LG’s WOLED evo design ensures better durability and broader format support for movie enthusiasts.
HDR Performance: LG C3 vs Samsung S90C
When it comes to HDR performance, the Samsung S90C edges out the LG C3 in overall brightness, making it the better choice for bright rooms or daytime viewing. Its Quantum Dot OLED panel delivers punchier highlights and maintains clarity even in well-lit environments.
However, the LG C3 performs more consistently in darker rooms, offering deeper blacks and better tone mapping control. Its support for Dolby Vision IQ further enhances HDR accuracy by dynamically adjusting brightness and contrast based on ambient lighting — a feature missing from Samsung’s lineup.
HDR Support Breakdown
LG C3: Dolby Vision, HDR10, HLG
Samsung S90C: HDR10+, HLG
In short, when comparing LG C3 vs Samsung S90C, Samsung’s higher brightness gives it an advantage for daytime use, but LG’s Dolby Vision IQ and balanced tone mapping make it the superior choice for cinematic, low-light viewing.
Smart TV Platforms: webOS 23 vs Tizen OS
When comparing the LG C3 vs Samsung S90C, both excel in smart functionality, but their operating systems cater to different user preferences and ecosystems.
LG C3 – webOS 23
The LG C3 runs on webOS 23, offering a streamlined and customizable interface designed for ease of use. It features:
Simpler navigation with a cleaner layout and faster app access.
Customizable user profiles, allowing personalized recommendations for each household member.
Superior smart home integration through LG ThinQ, Alexa, Google Assistant, and Apple HomeKit—making it one of the most versatile OLED TVs for connected homes.
Samsung S90C – Tizen OS
The Samsung S90C, powered by Tizen OS, emphasizes connectivity within the Samsung SmartThings ecosystem. It includes:
Strong compatibility with SmartThings for controlling connected devices directly from the TV.
Built-in support for Bixby, Alexa, and Google Assistant, giving users flexibility in voice control options.
A slightly busier interface but enhanced multitasking features for Samsung ecosystem users.
In summary, the LG C3’s webOS 23 shines for its simplicity and cross-platform smart home compatibility, while the Samsung S90C’s Tizen OS is better suited for users already invested in Samsung’s SmartThings environment.
Gaming Performance: LG C3 vs Samsung S90C
Both the LG C3 and Samsung S90C are gaming powerhouses, offering exceptional responsiveness and next-gen console support. Each delivers a smooth and immersive experience with:
4K 120Hz gameplay via HDMI 2.1 ports.
VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and dedicated Game Mode for lag-free performance.
AMD FreeSync Premium support to minimize tearing and stutter.
However, the LG C3 goes a step further with NVIDIA G-SYNC compatibility, making it a top choice for PC gamers using RTX graphics cards. Additionally, its Game Optimizer dashboard provides an intuitive overlay for real-time adjustments like black stabilizer, refresh rate, and latency monitoring.
In short, while both TVs deliver outstanding gaming performance, the LG C3 holds a slight edge in the LG C3 vs Samsung S90C comparison—thanks to its broader compatibility and more advanced gaming tools for both console and PC players.
Smart Ecosystem Integration: LG C3 vs Samsung S90C

Its Tizen OS works best for users who already use Samsung’s smart home platform, delivering consistent control through Bixby, Alexa, or Google Assistant.
