Studio Display (15-inch, LCD/ADC, 2000)

The Apple 15-inch Studio Display (LCD/ADC) featured an active-matrix LCD display and integrated two-port USB hub. It used a clear-plastic housing similar to the Apple Cinema Display. Its optimum resolution was 1024×768 and also supported 640×480 and 800×600.

This model used an Apple Display Connector (ADC). The design matched the aesthetic of the Power Mac G4 Cube models and the Mac towers of the time. A year after release, a larger 17-inch model became available using the same case design.
