"Amazon 4k" likely refers to Amazon's support for streaming and displaying 4K Ultra High Definition (UHD) content. 4K resolution has approximately four times the number of pixels as standard 1080p resolution, resulting in a more detailed and clear picture.

Amazon offers 4K UHD content for streaming through its Prime Video service, including a range of movies, TV shows, and Amazon Originals. To watch Amazon Prime Video in 4K, you need a compatible 4K TV or monitor, as well as a reliable internet connection that can handle the high bandwidth required for streaming 4K content.

Additionally, Amazon also sells a range of 4K UHD compatible devices, such as the Fire TV Stick 4K and Fire TV Cube, which can stream 4K content to a compatible TV or monitor. These devices also have Alexa voice control capabilities, allowing you to search for and play 4K content using your voice.
