Our Verdict
LG C4 OLED
LG QNED85T
The LG C4 OLED is much better than the LG QNED85T. The C4 displays significantly deeper blacks and more vibrant colors, so it delivers a more pleasing image. The C4 fights more glare in a well-lit room due to its better reflection handling, and it gets brighter in HDR, so highlights stand out more in HDR content. The C4 also has a much faster response time and supports 144Hz, making it better overall for gaming.
