To use smart features (including streaming services) on this TV, you'll need to create or sign into a Samsung Account. Without signing in, you'll only have access to standard channels and external devices, like consoles or blu ray players. This 50-inch Samsung TV has everything you need to give every blockbuster a boost. The 4K MiniLED display uses tiny pixels to light up the screen with bright and vibrant shades, while Neo Quantum HDR uses AI to adjust images and bring out as much colour as possible. But movies have to sound good too, right? That's why Dolby Atmos® delivers fantastic 3D audio to fill the room with epic soundtracks. The clever tech doesn't stop there. This model also has a cool combo of an NQ4 AI Gen2 Processor and 4K AI Upscaling, so those golden oldies get ramped up to 4K. Now the classics will look better than ever.
