LG C6 vs Samsung S90H: A Detailed Comparison to Find Your Next OLED TV

Choosing Between the LG C6 and Samsung S90H

In the highly competitive market for mid-range OLED televisions, the LG C6 and Samsung S90H stand out as two of the most popular choices for 2026. After extensive side-by-side testing, it is clear that while both offer the signature benefits of OLED technology—such as perfect blacks and wide viewing angles—the differences in design and specific feature sets make each ideal for different types of viewers.

Performance and Picture Quality

Both models deliver stellar performance, characterized by pixel-level dimming and exceptional color accuracy. Our tests revealed that while the Samsung S90H is slightly brighter in HDR scenarios, the LG C6 maintains a slight edge in overall consistency for SDR content. Notably, the C6 includes support for Dolby Vision, a feature absent in Samsung's lineup. For users who prioritize watching movies in the format intended by creators, the C6’s inclusion of Dolby Vision provides a distinct advantage.

Design and Screen Finishes

The most visible difference between these two TVs is their approach to screen finish. The Samsung S90H features an innovative 'Glare Free' matte finish that is incredibly effective at scattering light in bright rooms. However, this comes at a cost; in well-lit environments, the darker tones on the S90H can take on a slight purplish-gray tint. Conversely, the LG C6 retains a traditional glossy finish. While it doesn't handle direct light reflections as effectively, it maintains a deeper, more 'inky' black level, which is a hallmark of the premium OLED experience.

Gaming and Smart Features

Gamers will find plenty to love with both sets. Each TV comes equipped with four HDMI 2.1 ports, allowing for 4K gaming at up to 165Hz when connected to a high-end PC. Both also support Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). The smart platforms—LG's webOS 26 and Samsung's Tizen OS—both offer smooth navigation, though users may find themselves split on which interface they prefer for daily streaming.

The Final Verdict

Ultimately, the LG C6 is our top recommendation for the average consumer due to its balanced performance and the inclusion of Dolby Vision. However, if your living room is prone to harsh glare and direct sunlight, the Samsung S90H's matte-style display may be the superior choice for your specific environment.
