LG C6 vs Samsung S90H: which of these 2026 OLED TVs comes out on top?

The LG C6 and Samsung S90H are two top-of-the-line OLED TVs from the 2026 season, both boasting impressive features. In terms of brightness, the S90H edges out the C6 with a peak HDR brightness of 1,689 nits compared to the C6's 1,427 nits. However, the S90H's brighter screen does not necessarily translate to better real-world viewing.

During a comparison of Lawrence of Arabia, the C6 showed higher luminance and punchier white sands and blue skies in bright room viewing mode. The C6's glossy screen may also contribute to its superior performance in this area, as the S90H features a matte screen which might result in glare-free viewing.

When it comes to colors, both TVs deliver excellent color accuracy, but they often trade off whose colors are more punchy. The LG C6 performed better in movies with vibrant and vivid color palettes, such as The Super Mario Galaxy Movie, where its multi-colored characters appeared richer and deeper. On the other hand, the Samsung S90H excels in rendering the cartoon style colors of animated movies like Speed Racer, with more eye-catching hues and vibrant richness.

Overall, the LG C6 offers a more engaging color profile, while the Samsung S90H provides more vibrant and natural-looking colors in animated movies.
