Table 7-4: Matrox G400 VESA Modes
Memory Interface
The Matrox G400 supports a total of 32 megabytes of SGRAM/SDRAM memory
comprised of one or two banks of 8, 16, or 32 Mbytes each.
In Power Graphics Mode, the resolution depends on the amount of available memory.
Table 7-5 shows the memory configuration for each standard VESA resolution in pixel
depth.
