4K és un estàndard emergent per a resolució al cinema i a gràfics d'ordinador. El nom deriva de la resolució horitzontal, que es aproximadament de 4.000 píxels. Aquesta designació es diferent a les utilitzades a la indústria de la televisió digital, les quals son representades per recompte de píxels verticals; per exemple 480p, 576p, 720p i 1080p. 4k representa la resolució horitzontal perquè hi ha nombroses relacions d'aspecte usades en films. Així, mentre la resolució horitzontal es manté constant, la vertical depen de la relació d'aspecte amb la que el director decideixi treballar.
