Part 1. Why Do We Need 4K Upscaling

A 4K AI upscaling TV is a television that takes low-quality content to 4K resolution. It uses AI to upscale video, allowing content to appear sharper and more detailed on 4K displays. Since true 4K content isn't always available, this upscaling process helps improve videos of lower quality. It works by using algorithms and processors to analyze the incoming image. Then, it will intelligently add pixels by estimating what higher-resolution details would look like. But here's the deal: It doesn't actually create a true 4K but simulates a similar level of detail.

Why do we need 4K upscaling? We need 4K upscaling because, without it, SD or HD content would appear blurry on a 4K screen due to the resolution mismatch. Upscaling ensures all content looks clean and immersive on UHD displays. It delivers a better viewing experience and maximizes the full potential of a 4K TV.
