The iMac (Flat Panel) computer has a built-in color flat panel display. The display is backlit by a cold cathode fluorescent lamp (CCFL). The display uses TFT (thin-film transistor) technology for high contrast and fast response.
The display is 15 inches in size, measured diagonally. The display contains 1024 by 768 pixels (XGA) and can show up to millions of colors.
The graphics IC includes a scaling function that expands smaller-sized images to fill the screen. By means of the scaling function, the computer can show full-screen images at 1024 by 768, 800 by 600, or 640 by 480 pixels.
The graphics subsystem uses an NVIDIA GeForce2 MX and 32 MB of DDR RAM. It supports 3D acceleration and display depths up to 24 bits per pixel. When more graphics storage is needed, the graphics IC can also use part of main memory. For more information, see "Video Display Subsystem".
