The term "4K" refers to a video resolution measuring 3840 x 2160 pixels, which is four times the resolution of Full HD (1920 x 1080 pixels). The 4K resolution, also known as Ultra High Definition (UHD), offers exceptionally detailed and sharp image quality, ideal for large TV screens and monitors. The term "4K" comes from the horizontal resolution, which is approximately 4000 pixels. This technology is widely used in televisions, projectors, computer monitors, and even cameras for producing high-definition content.

In everyday life, 4K technology is used in many areas. For example, 4K TVs have become common in households, allowing viewers to enjoy movies, TV series, and sports with superior picture quality. Streaming services like Netflix, Amazon Prime Video, and Disney+ offer content in 4K, enabling subscribers to watch their favorite shows with extraordinary detail and color. Additionally, high-end cameras and smartphones can record videos in 4K, allowing content creators to produce high-quality videos.

In Switzerland, 4K technology is widely adopted thanks to the availability of compatible devices and the quality of network infrastructure.
