It appears that I have suffered the curse of Nvidia again, this time on my brand new work unibody Macbook Pro 13in. Under Windows Vista and 7 the Nvidia Geforce 9400M graphics card can only send a 640×480 resolution signal to projectors through the official Apple Mini DisplayPort to VGA adaptor.
It appears that I am not the only one, there is a large thread that is continuing on the Apple Discussions forum. There are a bunch of other people reporting the same issue, but Nvidia doesn’t have a solution yet. In fact, they have flat out said there are a huge list of unsupported (and will NEVER be supported) features. The following are from page 16 of the 190.62 Nvidia drivers release notes:
The following are features and functionality that were available in driver releases
supporting Windows XP, but are not–and will not be–available in driver releases for
Windows 7:
• High resolution scaling desktop (HRSD)
• MultiView Display Mode (for NVIDIA Quadro NVS graphics cards)
• NVKeystone
• Unified back buffer (UBB) controls
• OpenGL Video Overlays – This is an operating system limitation.
• Overclocking – GPU overclocking is no longer supported in the default GPU driver control panel. This feature is available in the NVIDIA System Tools software, which you can download from NVIDIA.com.
• GPU Temperature Monitoring – Temperature monitoring is no longer supported in the default GPU driver control panel. This feature is available in the NVIDIA System Tools software, which you can download from NVIDIA.com.
• AGP Settings Adjustment

• DVD/MPEG Extensions (such as was provided with Windows Media Center Edition)
