Samsung OLED S90D Series (2024) vs LG OLED evo C4 Series (2024)
For premium OLEDs, the Samsung OLED S90D Series (2024) is a powerhouse, boasting peak brightness of 1,200 nits, making it ideal for bright rooms. However, if you're a gamer, the LG OLED evo C4 Series (2024) offers an impressive 0.1ms response time, making it a top-tier choice for fast-paced gaming. In real-world use, the Samsung excels in color brightness with its QD-OLED technology, especially in larger sizes, but it lacks Dolby Vision support. On the flip side, the LG has four full-bandwidth HDMI 2.1 ports, which is rare, allowing for better connectivity with next-gen consoles. This makes the choice more nuanced than it first appears. Key spec: Brightness: 1,200 nits (Samsung) vs 1,000 nits (LG) - Samsung is brighter.
Why compare these? Both the Samsung OLED S90D Series (2024) and LG OLED evo C4 Series (2024) are high-end tvs competing in the same market segment. This makes them direct rivals for buyers looking for high-end features and performance in 2026. Understanding their differences helps you choose the right one for your specific needs.
