DVI je výstup určený na prenos analógového a digitálneho signálu, navrhnutý je pritom na prenos nekomprimovaného videa. Stretneme sa s ním hlavne v prípade PC a monitorov, ale môžeme na neho naraziť aj pri projektoroch. Delí sa na DVI-A (iba analógový), DVI-D (len digitálny) a nakoniec DVI-I (analógový aj digitálny). Ďalej rozlišujeme DVI single link s prenosom rozlíšenia až 1 920 × 1 200 pixelov 60 Hz alebo dual link, ktorý je schopný preniesť maximálne rozlíšenie až 2 560 × 1 600 pixelov pri 60 Hz (alebo 1 920 × 1 080 pri 144 Hz).
DVI-A slúži na prenos analógového signálu, dnes sa už takmer nepoužíva.
Pomocou redukcie D-SUB je možné prepojiť so starším rozhraním VGA.
DVI-D prenáša signál len digitálny, ide o štandardný konektor, ktorý nájdeme v prípade väčšiny monitorov.
DVI-I zvládne prenášať ako analógový, tak digitálny signál. Môžeme ho tak pomocou redukcie pripojiť do VGA aj do HDMI.
iDVI konektory sú kompatibilné iba jednosmerne. DVI-D teda zapojíte do DVI-I, nie ale obrátene.
Budúcnosť DVI
DVI zatiaľ zostáva populárnym štandardom. Už teraz je však možné naraziť na obmedzenia, ktorými sú napríklad chýbajúca podpora 4K alebo vyššia obnovovacia frekvencia pri rozlíšení 1440p. HDMI aj DisplayPort ponúknu vyššie rozlíšenie alebo napríklad podporu pomeru strán 21 : 9, prenos zvuku aj Ethernetu. Zatiaľ však aj najnovšie grafické karty disponujú DVI portom, takže tu s nami tento konektor ešte nejakú dobu zostane.
