The Apple Studio Display is a series of non-widescreen LCD and CRT displays manufactured and sold by Apple Computer, Inc. and introduced in 1998. After the 1999 introduction of the widescreen Apple Cinema Display, the Apple Studio Display line ran concurrently until it was discontinued in 2004. With the exception of the last model, the 5:4 17" Apple Studio Display, all Apple Studio Displays had an aspect ratio of 4:3.
Apple Studio Displays offered DB-15, VGA, DVI, and ADC as their display input. Some inputs Apple Studio Displays used were USB, Composite video, S-Video, ADB, RCA audio connectors, and headphone jacks.
Apple reused the "Studio Display" name nearly 18 years later for a different display model, launched in March 2022.
