The LG C4 is part of LG’s OLED evo lineup, known for excellent image quality, deep blacks, low input lag, and great picture processing. The Samsung S90D is Samsung’s OLED (or OLED QD depending on region) series for 2024, offering brighter picture enhancements, Samsung’s AI upscaling, motion improvements, and strong gaming features. Both are premium OLED TVs with many overlapping strengths; the question is which trade-offs are more favorable depending on your priorities.
Let’s make long story short: If you prioritize overall picture quality—with deep blacks, excellent color accuracy, and lower cost/less flashy extras—the LG C4 earns that crown. But if you want cutting-edge brightness, AI enhancements, and extra motion / sound features, Samsung S90D offers more bells and whistles.
Why Do I Recommend the LG C4?
- Superior OLED panel heritage — LG’s OLED evo panels have a strong track record: excellent uniformity, contrast, and color reproduction. They tend to require less aggressive image processing to look good.
- Better out-of-the-box picture calibration — Less need to tweak settings to get natural, pleasing color, which is valuable if you care about movies, streaming, cinematography.
- Lower risk of burn-in & more refined image retention — LG has refined its panel tech with the evo generation, helping with longevity for bright static elements.
- More affordable price for similar OLED performance — Often LG C4 is less expensive (or less premium-priced) than Samsung S90D, while offering similar core OLED strengths.
