The Samsung 77-inch OLED S85F is a flagship 4K smart TV using OLED panel technology for true per-pixel black levels and wide viewing angles, driven by Samsung's NQ4 AI Gen2 processor for real-time AI-based upscaling of lower-resolution content to near-4K quality. It's Pantone Validated for colour accuracy and includes Samsung's Adaptive Sound Pro, which adjusts audio output based on room acoustics and on-screen content. It runs Samsung's Tizen smart TV OS for streaming apps, and connects via three HDMI ports and two USB ports. At 77 inches with true OLED contrast, this sits at the premium end for home cinema and high-end living-room setups.
