Mac Pro: Display set to 640x480 resolution with Windows


In certain situations when you use Windows software under Boot Camp on a Mac Pro, the display may remain at 640x480 resolution (4-bit mode).  Selecting other resolutions may have no effect.


To use resolutions other than 640x480, you need at least two gigabytes (GB) of RAM installed in your Mac Pro.
