What advantages does the digital graphics interface have over traditional display interfaces?
The digital graphics signal sent by the Power Mac to an Apple flat-panel display provides distortion-free images that are sharper than those on a CRT display or a flat-panel display with an analog interface. Here s why: A CRT display requires an analog interface because it creates light and color from an electron beam. To create an analog signal for the CRT display from the digital data in graphics memory, the computer s graphics controller must perform a digital-to-analog conversion, which can lead to image degradation. Because all the Apple flat-panel displays are digital devices, they do not require this conversion to analog form. A flat-panel display using an analog interface must go through yet another conversion from the analog to digital signal, which leads to even more possible distortion. Apple displays receive a distortion-free digital signal directly from the graphics controller. Not only does this mean that all the pixels are razor sharp from screen edge to screen edge, it
