Apple Studio Display M7649
Max resolution of 1280 x 1024 pixels, 16.7 million colors, self-powered usb hub and connects via apple display connector (ADC).
The Apple Studio Display M7649 was first introduced in May 2001 to replace the Apple 17" Studio Display (CRT). It features an active-matrix LCD display, 16.7 million maximum display color, 350:1 contrast ratio, integrated two-port USB hub, and a viewing angle of 170 degrees. This model used the Apple Display Connector (ADC) which carries a video signal, USB data, and power within the same cable. This model was later discontinued in June 2004.
In 2007, customers of the Apple display filed a class action lawsuit against Apple, claiming that the inverter board of the Apple 17-inch LCD Studio Display was faulty. It caused a gradient dimming on the top or bottom half of the screen and a power light to constantly blink on and off in a short-short-long pattern to signal a problem. Apple denies all allegations, but agreed to settle to not risk supporting the cost of a lawsuit. Apple agreed to provide a cash refund to Class Members who paid for the type of repair covered by the settlement and who send in a valid claim form.
This monitor can be identified by looking at the back of the display and locating the model number in the bottom left.
