Both the LG 86UA7700AUA 86″ and the Samsung UN85U8000FF 85″ feature a 4K (UHD) resolution, with a resolution of 3840 x 2160 px, providing crisp and detailed images. The screen sizes are very close, with the LG measuring 86.4″ and the Samsung at 84.5″, making the difference in size negligible. Both displays use LED-backlit LCD technology, and offer 10-bit color depth, which enables a broad color spectrum and smooth gradients. The pixel densities are also similar, with the LG at 51 ppi and the Samsung slightly higher at 52 ppi, but this difference is unlikely to be noticeable in typical viewing conditions.
Both displays support HDR10 and HLG, enhancing the contrast and color accuracy for HDR content. The LG does not support HDR10+, while the Samsung does, offering an additional layer of HDR enhancement. Neither display supports Dolby Vision, which may limit the HDR experience for some users. Both models include anti-reflection coatings and ambient light sensors, which help optimize viewing in different lighting conditions. The maximum horizontal and vertical viewing angles are the same for both, at 178º, ensuring consistent image quality even when viewed from the side.
Regarding refresh rate, both displays are limited to 60Hz, which is standard for many large-screen TVs but may not be sufficient for fast-motion content like high-end gaming. Overall, the key differences between the two displays lie in the HDR10+ support and slightly higher pixel density on the Samsung, but otherwise, their specs are quite similar.
