It's a Radeon Mobility 7500 with 32 MB of DDR SDRAM. Supported resolutions are 640x480, 800x600, and 1024x768; all are using mirroring. Refresh rates are probably more dependent on the monitor you are using than on the iBook itself. The iBook doesn't support video spanning. It doesn't support older Apple monitors (eg Multiple Scan 17 or 20, etc.). That's about all there is in terms of specs.
