4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 3840 × 2160 (4K UHD) with a 16:9 aspect ratio is the dominant 4K standard, whereas the movie projection industry uses 4096 × 2160 (DCI 4K).
The 4K television market share increased as prices fell dramatically during 2014 and 2015.
Suggest naman kayo ng sites na may 4k movies + mabilis magload. Tinry ko yung Stremio + Torrentio kaso medyo mabagal magload sa Android TV kahit na 100mbps yung connection.
