What is 4K Resolution and 4K TV?Resolution is a term that describes the density at which these minuscule dots, known as pixels, are arranged on the display. Resolution is usually expressed in terms of pixel count, where more pixels result in a finer and higher-resolution image. Thus, 4K resolution is generally considered to produce high-quality images and videos with its high pixel count.
4K is a type of television screen resolution, typically referring to a pixel count of 3,840 pixels horizontally and 2,160 pixels vertically (denoted as "3840x2160"). 4K TVs are televisions that can support this specific resolution. -

What is the difference between 4K and 1080p (FHD)?4K TVs have four times the pixels of Full HD (1920 x 1080) TVs. This higher pixel density results in sharper and more vibrant picture quality, especially noticeable on larger screens. For instance, if you compare a 65" Full HD TV to a 65" 4K UHD TV, you'll see a clear difference in screen resolution.
• 4K UHD (Ultra HD) - 3840 x 2160 pixels

What is 4K Upscaling?When you watch lower-quality FHD content on a 4K TV, upscaling is the technology that increases its resolution, converts, and optimizes it to fit the display panel of a 4K TV. In other words, it doesn't just stretch the image — it upgrades it for the 4K display. Upscaling automatically analyzes resolution to reduce noise, improve details and provide optimum contrast and color so that you can view this content in 4K-like quality.
