4K is a screen resolution with about 3840 by 2160 pixels, which is four times sharper than Full HD (1080p).
The extra pixels make details clearer, so you can sit closer to the TV without seeing a blurry image.
Streaming platforms like Netflix and YouTube already provide 4K movies, but you need a strong internet connection—at least 15 Mbps in Kenya—for smooth playback.
Compared to older 1080p TVs, 4K models reveal finer textures in clothes, landscapes, and facial expressions, making the viewing experience more lifelike.
